[@3dpchiron709]

Good info - to improve profit margins, or reduce cost you could try: No stringing (sanding) + faster print -> use larger nozzle (eg 0.8mm) and print in vase mode with thicker layers. If you want a double walled part, make the model two nozzles thick, then remove a 0.03mm vertical slice (so it's like a chain link). Tune the flow, jerk & accel settings to get a strong yet minimal seam up the side. Thicker vase parts with internal structures are also possible depending how you make cuts. Harder to describe, but think of it like scoring the surface with a knife: you do 0.03mm cuts (smallest gap i've found is still recognised by Cura) in to one surface that stop 2 nozzle widths from the opposite skin, a bit like this ├│. You can imagine the slicer printing the outline, with every gap a double wall. Visual differences (gloss/matte) -> suggests slight temp difference between the hotends as Petg shine increases with extruder temps. Could measure and tune print temp for each of them. Old stock PLA parts -> perhaps a semi-insulated bag inside the package to save wasting them. Power/layer issues -> maybe on some machines the stepper drivers vRef is set a bit higher, causing them to run hotter. Cheaper Filament -> usually the manufacturer lowers costs by not drying (properly). Could use the warm printer cabinets to dry new spools. With a larger nozzle size, slight variation in filament thickness isn't noticeable.

[@MartinsonManufacturing]

Man, tons of great information here, thanks for taking the time to share all that. Sounds like you have a ton of 3d printing experience. You got me really curious about vase mode now, i'm going to have to try that out soon.

[@yourlocaltoad5102]

@@MartinsonManufacturing You could also buy a food dehydrator and use that to properly dry filament. These dehydrators can be bought very cheaply and they can cook out all the moisture in one night.

[@santopino2546]

I used to have false power loss issues on a cheap CNC milling machine, I resolved the problem by powering the drill with a separate power unit and leaving the electronics on the original power unit. The stepper motors generate quite a lot of EMF disturbance that could be an issue for the microcontroller and the communication with the PC, try shielding and grounding.

[@erronousactions]

To deal with your powerloss issues I'd look into running all machines on a UPS, because it filters all the incoming power from sudden spikes or drops, since it's constantly fed through the battery in them, so that way you're protected from 'dirty' spikes, which can cause these powerlosses.

[@goss4444]

In the I.T. world we call it "Brown Power", LOL. Servers are sensitive to 'dirty' power spikes and drops, so it is always important to run them from a UPS specifically for the constant power they output.

[@bradleyhovan9390]

Good change with dropping PLA. I believe the magic formula here was your designs-these exhausts are super simple for a slicer, which lowers your risk at all stages! Good job

[@SaltGrains_Fready]

HINT: Number the printers with the date they show up and go into service plus any letters or product id's.. That keeps it all in order by when they went into use as well as age etc.

[@MartinsonManufacturing]

Definitely a great tip here!

[@WarrickTaylor]

And keep a service log somewhere, that way you will know if a specific machine has a recurring issue rather than something common to all the machines on occasion. Definitely serial number the printers.

[@SaltGrains_Fready]

Each machine should have a log notebook with a date and the file name of what ran that day entered as it is run. Log Temp of Bed, nozzle and FR on the end of the line, which slicer, settings and any adjustments for that particular extrusion, as well as noting the filament that is in use with the day it's put on the instrument when that changes. After awhile it's a great log to refer back through to see situations that happened, and also for a repeat print job of something specific from awhile back and how it performed and produced.

[@KLP99]

Please consider keeping your printers with the same numbers they have but in each group change them to A, B, and C and do 1A, 1B, & 1C, etc. That way you'll be able to keep them separate. Just a thought. I'm not sure it's a good idea, but my printers are colored in other words I printed fan shrouds in blue, red, orange, and green. So my printers are called blue, red, orange, and green in Octoprint themes for each printer. That way I know which one I'm attached to when I'm sending a job.

[@3dvince]

Don't switch to ABS!!! The whole ABS is stronger than PETG thing is a big old myth that as been busted by Stephan from the KZbin channel CNC Kitchen. ABS requires much higher print temperatures wich is going to cause many problems on your stock Enders (trust me I ran 5 enders on ABS for a while and it was a nightmare). What Stephan showed is that not only PETG is similar to ABS (strenght and temp resistance) PETG ended up having stronger layer adhesion than ABS. ABS was one of the first filament to be resistant and that's why it's got this reputation but it's just a myth now.

[@MartinsonManufacturing]

Cool man, thanks for sharing that! PETG is so much easier to print with anyways so that makes my life easier.

[@dwintster]

Thanks for the video, I have a background in Industrial Design and got into 3d printing almost 20 years ago but have gone on a different path since. Looking for my first personal 3D printer to get started. I used to love the SLA at work but FDM like the Ender 3 that you have might be a better place to start. Printing so much it might be worth it for you to look into doing small production runs with soft tooling. Take a few printed parts build a silicone mold and cast your parts out of a highly density urethane. Do some research and see if it works with your parts. Thanks again for the great vid.

[@spencerlange125]

Yes, PETG is amazing. It is my go-to material. I only use PLA for prototyping and working out designs.

[@PressRToWin]

That being said, for higher temp applications PETG doesn't cut it.. my prusa mk4 started to soften and lose belt tension when I had it in an enclosure and it hit 50c inside

[@dorjanhajdari2670]

1. It could be spikes in peak demand dropping voltage for a split second just enough to trigger the warning. 2. The probability of getting an error increases with frequency and quantity. The more you use the printer(s) and the more you have, the more likely you are to experience an issue.

[@oneheadlight8000]

PETG is plenty.. We print gun parts and they hold up just fine. We also use ASA but you need to be more concerned about VOC's with that material. ABS is pretty much obsolete unless you need a bunch of pretty colors. ASA prints more easier, has the same or better mechanical properties, and has a nice matte finish. We use 3DXTech for most of our filaments. Edit: We also print with ASA on scotch brand blue tape. 85C bed.

Loved your video! So I started out with one 3D printer from Aldi, an i3 duplicator rebadged. After a few years or printing random things I needed, a mouse plague came along here in Australia and I was printing auto reset traps 24/7. I went from one to 4 printers to keep up with demand.

[@dang4937]

Thanks for putting this together, it is inspiring. I'm curious about your reasons for 3d printing this part vs injection molding once you got to some scale

[@Weirdomanification]

Some possible reasons: Initial expense was still to high to justify, especially when there's a high risk the sales drop off. Injection mold shop could take his design and directly compete. Injection mold shop could raise unit price once he was invested. Injection mold shop could end up having terrible quality control. Injection mold shop could go bankrupt. Molds could be seen as assets and be locked in legal proceedings. Labeling the part as 3d printed helped when marketing to other makers.

The video was helpful, thanks for sharing

[@johnrobinson3642]

Great video, that was really interesting, thanks for sharing. I have a couple of suggestions that you might like to try. First of all, when printing ABS, try out a PEI bed. It will stick perfectly, and release easily when it cools down. I print a lot of ABS, and I put down my first layers at 75mm/s on PEI, no adhesive required. Also, consider trying klipper firmware on a test printer, it has far superior kinematics. That translates to much faster printing without loss of quality, as a rule you can expect to double your print speed just from installing klipper alone. My standard print speed using klipper on my Ender 3 V2 is 150mm/s. You need to use a raspberry pi which adds expense, however you will be able to substantially increase productivity of each machine, so you won't need to spend more money on extra printers, or space and cabinets to house them. I don't run a print farm yet, but I hope to soon (printing car parts in ABS or ASA), but those are things I do on my personal printer (which pretty much runs 24/7) and so will definitely implement on other printers. Having said all that, I don't know how much printing faster will add to wear and tear on the printer, and whether the benefits outweigh the cost/downtime that comes with that, but I aim to find out :) Thanks again for sharing.

[@MartinsonManufacturing]

Thanks for your contribution, lots of good advice. I've actually been having an issue with my ABS prints fusing to the bed lately so i'll definitely give that a try. Is there a particular PEI bed that you would recommend? This is the first time i've heard about klipper firmware so i'll have to look into that more. Saving print time would be a huge help!

[@johnrobinson3642]

@@MartinsonManufacturing I'm in Australia, so I tend to buy most of my stuff from China as shipping from the US is expensive. I use the Energetic PEI plates, but you will have a much wider range available assuming you are in North America. Do a search on YT and you will find heaps of info. Klipper is a game changer. Seriously, once you have tried it, you won't look back. On your first installation, you will have it all up and running within a couple of hours. And if you mess it up or just don't like it, you can revert back to Marlin in less than 5 mins. Aside from the better kinematics, klipper as a number of other significant features: a) Everything can be configured in the config file, no need to recompile firmware as with Marlin, b) Pressure Advance allows you to easily tune the filament flow through corners, so you can eliminate bulges. Marlin has a similar feature called Linear Advance, but it is not compatible with the Creality mainboards, and c) Resonance Compensation allows you to tune out ghosting/ringing. I would suggest looking at the TeachingTech YT channel, he has recently convert several printers to klipper and he walks you through all the config process. Also, feel free to contact me if I can help, I'm happy to walk you through it. Good Luck! :)

[@comradejordan5738]

You could be experiencing differences in part shade for a couple of reasons. Usually this is due to inconsistencies in reading and different PID tuning settings for each of the printer. Silicone socks could have various different amount of use and wear. I'd suggest if you try to get the most consistent printing temperature and consistency, to make sure all nozzles are from a consistent manufacturers, and the heater cartridges and thermistors are all inserted with thermal paste (boron nitride thermal paste from slice engineering works great). Don't forget to PID tune each of the prints with their part cooling fan on at the speed the filament of use will print at, and try to PID tune each of them with the door closed and the other printers running to simulate a real environment.

[@comradejordan5738]

This should reduce almost all of the shade variation you are experiencing, the only variables that should be left are the filament humidity and consistency.

Bumped into this video since I just bought my first 3D printer (Ender 3 V2) and have been binge watching 3D printer videos. Although I am not into a 3D printing farm your video was a very nice video to watch. It is always nice to see how someone's business starts with a concept and flourished into a nice at scale operation. Wishing you good luck for your continued growth in 2023. Since you have these many printers running continuously, a couple question if I may - what changes have you made to your stock printers to ensure quality and reliability. Like I keep hearing about replacing stock bowden tube with better quality Capricorn tube, all metal hot-ends, metal extruders etc. Also it will be nice if you can put together a video showcasing some routine maintenance. Thanks and good luck.

[@naasking]

Thanks, you have a great process it seems. Some good ideas if I ever wanted to sell something I designed. I think other people have mentioned the electronics overheating as likely causing your issue. Running electronics at higher temperatures also reduces their life expectancy, so there's added cost beyond just failed prints. Maybe move the electronics to a separate cooler area from the heated chamber to extend their lifetime and improve their reliability. There are also fire hazards with 3D printers, both from the electronics and the heated printing area. Less likely these days but still possible. Maybe replace or at least line your wooden enclosures with cement board on all sides. Cheapest option I've found for building a fire resistant enclosure. Separating the electronics means they should ideally get their own enclosure(s). Also maybe add a fire detecting automatic fire extinguisher. I've seen them on Amazon.

[@MartinsonManufacturing]

Great thoughts shared here, thank you for commenting. I'm planning on moving the electronics outside the enclosure in the coming months.

[@elHippieSupremo]

I had a similar problem with my new ender 3 (first 3d printer!). A certain model I was trying to print would keep failing at the same level about 12 hours in(layer shift, then the print just stopped on the next attempt). Apparently the motherboard overheats on these things. Fixed by adding an exhaust fan to the side of the motherboard enclosure. Also opened up the enclosure, moved the ribbon cable to the side, since it obstructed the airflow from the fan to the ARM processor. Finally spliced in the board fan to the heating block fan, because the mobo fan would actually only run when the parts cooling fan was running before. Have been running it up to 4 days at a time without any problems. This is what gave me the idea: hackaday.com/?p=461364 .

Dude, That is great. I would have an overtemp and smoke detection with Raspberrry Pi / Arduino and a relay. I am not sure about these days but many of those boards shipped with thermal runaway protection disabled by default. Thermal runaway will save ou if a thrmistor cable breaks or the thermister falls out but you really also need something to guard against shorted hotend and heatbed mosfets failing short circuit - the micro would be unable to shut them ff as they would be 'fused' on. Only way to deal with that really is either a raspberry pi with temperature failsafe and smartplug or relay plugins of a custom job using something like an arduino. Great to see it took off.

If an issue you may need to punch 2 holes in the cabinets per printer, for a cool air intake and exhaust, in a contained system as to not alter your hotend & bed temps. The power supplies are probably of not high quality, I had one fail in just 6 months of moderate use. Cheers

Have you considered moving your production to injection molding based on the high demand? It could simplify a lot of your production process, like more reliability, production time, employee's costs, complexity in maintenance etc. Also, have you considered "heat" to your electronic as to your random power loss problem? Maybe you can extend the cabling and put the electronics outside of your cabinet. In any case, really impressive, you turned your hobby into a retable business.

[@MartinsonManufacturing]

Awesome thoughts, thank you for your contribution. Injection molding is something I've thought a lot about. I recently got a quote from a company in Illinois but it was far outside my price range because my part requires slides. I think I'd have to get it done overseas for it to be viable but I'm not crazy about that either.

@@MartinsonManufacturing Outsourcing to China could be viable, but quality control and specially communication can be really challenging, if you going that route hire a Chinese person locally who can speak fluent English and not other way around. I worked as a network technician for many years, and most hardware failures are result of inappropriate heat dissipation. You'd be amazed how a couple of failed fans can do to a server. Rule of thumb is all electronics required some sort of heat dissipation, if it is passively cooled it only means that the heat is dump to the environment. Here is another optimization you can do. Most psu that comes with the printer are in the realm of 70 80% efficiency. You can buy really cheap server grade 1.1K watt PSU for around 50 bucks and mod the 12v output with a breaker board. That can easily powered 2 to 3 printers and the efficiency are around 90% to 95% depending on the "gold" or "platinum" standards. That way if you scaling up your 3d farm, you could save some real cash in power. ;)

@@MartinsonManufacturing Your power issue is coming from the 3D printer power supplies. The majority of them have over temperature protection on the main board. Once the intrenal temperature reaches the preset limit the OTP shuts down the power. This is occuring because you put everything into a cabinet and it's getting too hot. Moving the power supplies outside of the cabinet will solve your problem.

I love my ender 3... as your comment about odd things going on with your "ghost in machine" I had my ender 3 for 2 years now.. but for the past couple months my printer seems to like adding it's own personal touch. It print stuff that's not part of the model.. it's random.. yesterday was the most interesting print were the printer added it's own creativity. What it printed was the shape of the model but everything else was not part of that model. What was most interesting to me was the very first couple layers the bottom or floor of the print. It completely looked like a piece of plastic you see on your purchases household items, there were no lines what so ever... it was a very strong, yet thin print that had a semi glossy shine which the white filament used was flat white. It's definitely the type of results I would love to get from my prints.. but my ender 3's not willing to tell me it's secret..

[@MartinsonManufacturing]

Your printer “adds it’s own personal touch” Lol! I can relate. Yeah man, the inconsistency stuff drives me nuts.

[@jcracoustics]

Hey! Great video! Hoping you see this as it’s an old video now but I couldn’t help but wonder since you are printing lots of the same part (and clearly shifting volume) why you don’t go the route of having it tooled and injection moulded on the well established parts. The part cost would be less after you get over that initial say $1500 tooling cost and you wouldn’t have defects or sanding to deal with. Then you can use your farms to run new product lines before committing the next successful one to tooling. You could also then go the Amazon FBA route on those parts so your dealings would be manufacturer straight to Amazon warehouse and nothing for you to deal with and easier to scale. Either way great video and super happy for your success!

[@MartinsonManufacturing]

Thanks for the comment man. Injection molding would be a great way to go. Do you know anywhere where I can get tooling done for $1,500? The cheapest I found in North America is $34,000.

[@jcracoustics]

@@MartinsonManufacturing Wowzers that's a high quote! Most my experience is with China. I get a lot of trays/cases/etc. tooled for the hydroponics industry. Our work has a China office though to make communication easier. Recently used DongGuanShi YiSheng Packaging Prouduct Co.,Ltd and a mold cost for a 300 x 600 x 15mm thick reusable tray was $1800 with unit cost $0.4350. I can only imagine your prices are due to them being from North America or potentially the shape being a tube means the mold needs to be 3 parts and therefore more complex. Might be worth chatting with a plastics design firm on the phone. Quality has always been good from China too.

[@MartinsonManufacturing]

Man, that’s a great price. Thank you for sharing your contact. My current design would require a sliding three part mold so that’s probably why it’s so much. I’d like to look into this more. Thanks for getting back to me with the additional info!

[@khulekanintini425]

I am really inspired by this video and would like to start a 3D printer farm.What do you think is the best product to start off with?

[@rayturp6742]

Increase your retraction speed and or distance to reduce your stringing. Also, look at reducing your temp because they are in a cabinet. You may be melting it too much.

[@chadkoyan3096]

You should try running a UPS if your still having power loss issues.

[@MartinsonManufacturing]

Definitely a good idea. I think the solution is either a UPS or trying to keep the electronics cool. Someone else mentioned that the heat may be causing the issues so I think its one of these two things. Thanks for the idea!

[@waynefilkins8394]

I would have just gotten those ups battery backup things. I have 2 of them and I run my pc and mining rig through 1 and 2 printers through the other. Got 2 printers out in the garage that don't run through one yet but never have that problem so yea that is really an odd problem to have. Has to be something to do with your fuse box or something.

[@Michal.mikhael]

Nice! I wouldn't imagine such 3d printer class would be good for this "proffesional"/commercial usage.

[@jstro-hobbytech]

Good for you man. It's good to see nice guys , that are also talented get ahead. I hope you become a millionaire my friend.

[@MartinsonManufacturing]

Thanks man :)

[@rayturp6742]

If you change to ABS you will need to move your power supplies outside of your cabinets. They will overheat if you dont.

[@MartinsonManufacturing]

Thanks for the feedback!

[@tomhutchins1046]

AND the transformers will run on 220 just flip the switch an wire them up. It will cut the power bill in half. Will also heat up faster be safer and be much more stable.

[@sergetheijspartner2005]

I was hoping for more things like Business plan, pricing, overhead, what goes to taxes, what is your profit margin etc...Don't worry I am not IRS I am not even American so the tax laws are different here in Belgium, but maybe do a video on that?

[@MartinsonManufacturing]

Thanks for the recommendation, i'll be sure to address those topics in a future video.

[@MassiveBallics]

I myself and trying to get a farm started as a small LLC. Something I'd love to see is how to start if you have a video for that part.

[@MartinsonManufacturing]

Sure, I could do that. What in particular would you like to see? How to setup the business? How to find a product to print or how to find client? How to market? There’s so many aspects to it and each one could be it’s own video.

[@MassiveBallics]

@@MartinsonManufacturing How to setup the business? How to find a product to print or how to find client? How to market? I fear that Im more into the tech side of 3d printing and not much on the design and business side of things. I have 4 printers and I am learning to work with the differnt types of filaments from pla, pla+,petg, asa, abs is next. That cabinet you have looks great and is sparking ideas for storage place in my garage. that will help with the heating and cooling part.

[@MassiveBallics]

@@MartinsonManufacturing My current setup will be manages by using klipper as it seem I can add about 3-6 printer per raspberry pi. and because I have a lot of spare PC's I might use one of those as my print server... I know I need to find a good printer that is cheap but not too cheap that is a bad printer and enders seems to be that printer. as far as the idea. I am starting to look at some classes on fusion 360 and how to use it. but right now Im just printing or test printing items for fun. I have a coreXY and Delta printers.

[@MartinsonManufacturing]

Awesome dude, it sounds like you’re in a good place and off to a good start. It’s sounds a lot like where I was 4 years ago. I’ll definitely make a video on this soon, but for now my advise would be, just START. It’s okay to not know what the heck you’re doing. That’s what being an entrepreneur is all about. But, I assume you’re good at solving problems so you’ll eventually figure it out. Don’t feel like you need to have everything figured out now, you’re a smart guy and will figure it out when you get there. Just start moving in that direction in whatever small and imperfect way you know how. I look forward to sharing more details on my journey in a future video. Maybe by the end of February.

[@MassiveBallics]

@@MartinsonManufacturing thank you again for your help and I look forward to learning from you.

[@tisaksen30]

Only reason to use abs is for temperatures up to 100°C. your ender 3's will need a different hotend to print abs. The stock one will break if you print abs, i promise. I have been building and using 3d printers since 2012, trust me i've been through all the problems you can imagine with 3d printing.

[@marianososa4309]

How do you print PETG on an Ender 3??? Do you use an all metal barrel??? Excellent job!! Congratulations!!

[@roblucas6097]

Very nice setup you have for your printers. Do you have instructions on how to move the extruder to the top rail like you did? I would like to do the same with mine.

[@IMRROcom]

Selling on Amazon? What is the Cut/Percentage Amazon takes? How do you set up a Amazon Store?

[@dwpelland]

Thanks for sharing. This is vauable info.

[@swindmiller]

Enjoyed the video. Happen to have an STL you would not mind sharing for the fan mod. I run 5 Ender-3's and have the issue with the strings sucking up in the fan. Over time, causes a decent issue :)

[@MartinsonManufacturing]

Sure, no problem. Shoot me an email and i'll email you back with the stl file: [e-mail]

[@GAMarine137]

Thanks for the tour

[@OG96932]

when you leave your printers untended , you risk burning down the premises, what safety measures do you use, when using multiple printers

[@ajhartmanaero]

Very interesting on your amazon comments. I've heard good and bad about FBA stuff.

[@tsangs3363]

Good for ur business

[@axleotle_budies]

Awesome. Thank you for sharing. How do you research market need?

[@byronwalker3606]

Any chance you could share the link for the white cabinet?

[@mattwroe4776]

In the uk plumbing parts are made to British standard specs so I could print but people using them may not be insured when using them, home owners void their insurance ect, this sunk my business idea

[@captmcloven2137]

You have a really nice setup. I have noticed I to am looking to get into the 3D printing business. A lot of people have asked me for specialty parts. Is it best to just find parts that you can print in bulk? How do you have all the printers linked? I use Octoprint with raspberry Pi 4 running wireless on mine with Cura as the slicer. Your printing ABS parts with stock Ender is down right amazing. I look forward to seeing more of your content and hearing back from you. Great job on your business and content.

[@captmcloven2137]

I subbed and hit the notification button cause you just did not spit out information. You did a walk through and that is what content is all about.

[@MartinsonManufacturing]

Thanks for reaching out man. As far as one-off specialty parts or bulk prints, I think the best is to just start doing various jobs for people until you find a niche that you can really focus on. I started out offering 3D printing services. Several customers were asking me about laser engraving so I eventually bought one. Two months after buying the laser engraver I 3D printed a part for it to solve an issue that was bugging me and then it eventually became a fulltime job selling those parts. I absolutely love printing in bulk because you can really start to streamline your process. That being said, I'm starting an offshoot company to offer services because there's a huge need for it. I don't have my printers linked. Good ol fashioned micro sd cards :) Thanks for your support!

[@Nicks3D-dimension]

Great video and awesome print farm

[@rawreffincake]

at 5:00 minutes you show a cooling fan duct upgrade that you made, do you have a link to the upgrade?

[@you-dont-know-me]

Are you not worried about potential hazard such as fire?

[@MartinsonManufacturing]

Great question. Yes and no. But being that I run it like this all the time, no not really.

[@bensimonpouf]

Yeap, EMI/EMC mains filter would help I am sure !

[@MartinsonManufacturing]

Thanks for the tip!

[@travismiles5863]

Thanks bud appreciate ya!

[@wilmercb]

Congrats!! wishing you the best to come!!!! ✨🙏🏼 ...have you tried the Prusa printers? Thanks

[@MartinsonManufacturing]

Thank you! Not yet, but I'm really thinking of buying one soon.

[@danielsabou1695]

For your type of products, a higher end dual printer should save you so much time, maybe even money. Stringing/power losses are problems for the cheap printers, a higher-end well calibrated printer shouldn't give you these problems. Plus you have the ability to print 2 in the same time. Molding is indeed the fast/easier maybe even cheaper option but with so many supplies shortages lately and transport problems, keeping production inhouse at least of the time being is the thing to do imo. How does your Amazon margin compares to your Etsy shop ? I would imagine Amazon takes a bigger % of the profit ? Do you have to invest in PPC or can you rank organically ?

[@MartinsonManufacturing]

Good thoughts shared here man. I've thought a lot about starting to upgrade to more expensive, more reliable printers. It may be something I need to bite the bullet on and just do it. Amazon takes 15% and Etsy takes 8%. However, my sales tripled when I moved from Etsy to Amazon. I've been fortunate enough to never have to pay for marketing. My customers are Glowforge owners and my KZbin channel is mostly Glowforge content so that's how they hear about my products. I listed a few other products on Amazon and started to rank organically after about a month and a half. All that being said, I just moved off Amazon to my own website hosted by Shopify, so we'll see how that goes.

[@Waku117]

@Martinson Manufacturing I'd recommend a stacker s4. My favorite printer prints 4 objects at once, highly precise, no fiddling or anything. I also have one for sale if interested

[@MartinsonManufacturing]

@@Waku117 Oh wow, I didn't even know those existed, thanks for sharing. My only question would be, if the extruders are say, spaced 2" apart and your part is 3" in diameter you wouldn't be able to utilize all four nozzles. Would that be correct?

[@Waku117]

@Martinson Manufacturing all 4 nozzles running at once, it'd be 345mm x 96mm × 650mm. But remember, you don't have to run all 4. You can print with just one nozzle or 2 or even 3. It's also the best multi color printer I've used.
