The E3D Tool Changer Is Finally Here! - Let's Review It

[@robswain5264]

I'm going to take a wild guess, and say that your background is in industrial "design", not engineering. If you've listened to any of the press about this machine, E3D has said, over and over, that their system WILL be overbuilt, because they want to push the limits of accuracy and repeatability. Your diatribe against engineers in this bit honestly made me lose a bit of respect for you. Especially since you imply that you know the engineers of E3D, your comments seem unreasonably harsh.

[@CutterSlade001]

This is not a 3D printer! Your criticism of over engineering is nuts. This is a manufacturer development platform that is overbuilt as to not misrepresent the toolchanger mechanism as a whole! Furthermore you should be thankful they even sell this to Joe Shmoe they could have easily restricted it to their development partners. To be able to buy a honestly overbuild machine like this is a real treat to every enthusiast. You can buy "bean counter" machines on every corner. This was, for good reason, not subjected to bean counting.

[@trailblazingfive]

In half a year someone from China will sell a functionally similar solution for a fraction of this machine's price and at that moment you'll realise that you got screwed. As they say - there's a sucker born everyday.

This guy, Design Prototype Test always sounds like the most full of himself, idiotic guy I could imagine. I clicked the video because I'm interested in the E3D tool changer, however, as soon as he started talking about industrial design etc, jesus christ, I'm out. What a douche.

[@SanjayMortimer]

No marketing input, no industrial designer on the project, no beancounters sacrificing performance for cost concerns. Built entirely by engineers, for engineers. Put it out there and see who wants it. Exactly what we intended. :D It's not a printer, it's a Dev kit. It's meant to be like this. Bulletproof. It's meant to be a technical tour de force, for evaluating a new technology so others can learn and develop it further. The cross bar was cheaper than the carbon part, it was also stiffer and more reliable due to matched thermal expansion. The additional lightweighting machining probably added less than $40 to the machine. Worth it. If you want a toolchanging printer you can take out the box and looks beautiful, with user centric design then wait for our development partners to bring one to market. If you want a Dev kit to play with something cool and new this is out there for the hardcore, the enthusiasts, the developers pushing our industry forward. I hope they enjoy it.

[@ViceChief]

​@@fredriklarsen5968 Yeah, I unsubscribed. You don't get Product Design or Industrial Design departments involved until you have done your early technology development and built your technology development platform (which is what this is). He acts like he's an expert in these spaces but it's not in evidence. His animus toward "engineers" is embarrassing.

[@AsbestosCrisis]

Thanks for posting this. Very excited to see how it progresses! As for the budget I'm pretty sure Sanjay said in his initial 'brief' that this was a printer built and designed with no budget restrictions in mind - just a project to get the most awesome printer they could manage.

[@DUIofPhysics]

[@Charlesstrahan]

"The number one problem I have with it is that CNC crossbar, [...] why on earth spend all that time and all that money [...] I want the carbon fiber that you were talking about [...]" That was covered on their blog earlier this month: "The stiffer the better, right? We’ve said goodbye to the carbon fibre bar and replaced it with fancy machined aluminum and oh boy have we’ve seen a drastic increase in stiffness; in fact it’s now twice as flexurally stiff and 3 times more torsionally stiff. In doing so we’ve only increased the total flying mass by a couple of percent and the machine can now carry the tools with far less pressure, win win! Additionally, it solves the issue with the differences in the coefficient of thermal expansion between carbon fibre and steel. The carbon fibre bar expanded at a very different rate to the Hiwin Rails and consequently we were seeing bending that caused issues with calibration and bed leveling; this has now been eliminated." See their post titled "ToolChanger: The update you've all been waiting for"

[@DesignPrototypeTest]

Thank you for the information Charles.

[@bobo-cc1xw]

I feel this review is a little unfair. E3D is a 3D printer accessory company - a hotend company their customers are big printer manufacturers including those in China. The worst thing they can do is a build a mass market 3d printer that annoys their customers (printer makers) and they are not setup to be 3d printer company see Bowden tube length or the “big box” printer they built before. This is a reference system. Why build it? To show that a tool changer system works and beats current designs. A tool changer happens to need 4 hotends rather than 1 for MMU which is good for E3D. Not that it does not have technical benefits but marketing wise it is very clear why this is good for E3D. They will say for a 2k system it is the best that you can get. I think they are right in this. At that point you are competing with a tricked out prusa or a Ultimaker 2 a craft bot etc. It has more nozzles, a toolchanger will be faster and has rails. Is a 2K printer worth 10x the price of an ender 3 maybe not depends on apps. Is 2k good vs an Ultimaker s5 at ~7k, maybe depends on the application. The rail is an afterthought, carbon fibre had expansion issues so they put in something that worked. Arguably a steel on aluminium rails had expansion issues. It is not refined but show me a product without an engineering kludge or two in there because something went wrong at the last minute. Evil me says the Bowden is a purposeful mistake to make it bad to stop average consumers playing with it. Planned obsolescence in the sense of purposefully tanking your own product so it is not too good. Nice to see a review and another view point.

[@Underp4ntz_Gaming_Channel]

@Neil Siebenthal Yeah he got a negative view on things (i do too) but come on... He is always complaining about Chinese printers that could do this or that better. but you only pay a damn $129 with free shipping worldwide for it... what's there to complain about. NOTHING! I also understand being critical on things improves products / features but every video i check... its only negative and a lot of hypocritical stuff too. Oh and how he names parts of a printer sounds like he doesn't know where he's talking about at all. Like M8 Hardware? wait what? hardware right? these are damn hex cap screws with simple t-nuts.

[@wickedcoyote271]

I thought when they had perfected the prototype that had said they didn’t really want to make a kit. They wanted to set a tool changing standard and let others make kits. It looks like they definitely didnt compromise in the components. As for cost, they have to fund R&D somehow before the knockoffs flood in.

[@biziluxgames8924]

Did i miss the review part of this video? Missleading no?

[@hobohacker258]

You lost me at mangling the threads. Worst advice I've come across this month. Just use a magnet or two to bring the T-nut up so the threads can catch *correctly*.

[@bmull81]

Hobo Hacker - So true!

[@paulf5351]

Happened to me on another machine. I took the tail off and started over. The magnet idea is brilliant.

[@ChristopherGoggans]

I feel like I remember Sanjay and some of the other E3D guys saying on one of their livestreams that they were overengineering and overbuilding the design both as a proof of concept, and also because they are wanting it to serve as a platform for many other tools. The first thing that comes to my mind is that the system may have been overbuilt with a high performance CNC spindle in mind. I think they also described wanting this to serve as a example of what can be achieved with their toolchanger system, both in precision and extreme accuracy. I also remember Sanjay saying they were having massive issues and delays getting the linear rail from Hiwin with the preload they wanted. None of this is meant to be an excuse for the cost, I just wanted to share some of the stuff that I remember them talking about, and hoping to provide more info for people considering their toolchanger. Edit: I'd bet that's one of their new Mordor heated beds they've designed. These new beds get and sustain over 100°C for printing PEEK PC and other even more exotic plastics. Apparently they had to get custom beds made and somehow use the aluminum anodizing process to bond the silicone heater pad to the bed. The crazy mounting method was needed the other adhesive methods they tried failed under consistent extreme heat. Anyway, more fun food for thought. It definitely sounds like their instructions could've used a few more revisions lol.

[@trailblazingfive]

No change for running a spindle on this machine; too small of cross sections - not enough 2nd moment of inertia - not rigid enough. It's overengineered but definitely not overbuild.

[@Deneteus]

Yeah the problem with the bonding process for silicone is that there aren't alot of high temp adhesives that can survive the abuse.

[@Tkamsker]

I did build that printer as a base for my projects and i am very happy about it. The X bar is simply CNC Porn and i like it. I am under the impression you didn't fully understand what you buy when you applied for the queue. It is an demonstrator for people who know what they are doing and not a finished product. so yes bowden and 3d printed parts screws etc have to be added. But it really rocks, i do now an cheaper version based on that for BLV based corexy printers. lets see which price point is possible

[@AntiVaganza]

"Could have cast the CNCed part instead to save money..." - really? For a low volume run, it makes a whole lot more sense to CNC this part. No mold cost (likely not cheap at all) and no outsourcing to have it cast. Oh, shit, I just heard the rambling Jony Ives comment. I, too, admire his skills (Ives') and the design icons he has given us, but speaking of 'overpriced' products - pick any iPhone... I agree the E3D printer is expensive, perhaps too much so, but man, your Ives analogy and insisting that because he happens to be British, then this British printer should be cheaper and prettier is just "funny"... (and I am literally typing this on a "magic bar" 15'' MPB with three broken butterfly keys)

[@ktraglin]

Maybe they said "put thread lock on the threads" in part, so that people don't have to "mangle the threads" to get the t-nut to rotate as desired? I imagine any of your former ship-mates (specifically those who were engineering technicians) would have been able to help you better understand assembly of more complicated mechanical things such as this. Then again, that old saying, RTFM seems appropriate, here.

[@nictamer]

Re: industrial design Sanjay said they were NOT in the business of selling printers. They want to be in the business of selling tool-changing parts. So, yeah, they didn't make this kit so that it would be a competitive 3D printer, they made it so that it's a reference design for their parts.

[@adriaangreyling7658]

The carbon fiber cross beam was dropped because the inserts pulled out from the Carbon fiber (expanding to a different rate than the mgn9 rail on top when heated) I saw a video of Rene Jurack having to replace them as well, most of the details are explained in the blog post...

[@adamchambers7502]

Yes but the cnc machining is definitely over done. It's more pocketed than an aerospace part. I m not sure mass is THAT much of an issue. Cnc machining like that costs alot of money. Barstock passed once or twice in the mating faces could have done? It is very sexy though. As a mechanical design engineer who has been chewed out for the exact same thing before, I'm calling over engineered on that part!

[@adriaangreyling7658]

@@adamchambers7502 the point of introducing the carbon fiber rail was to reduce the weight of the moving mass, to which the system was spec'ed, if they'd slapped on a rail that suddenly increases that by 70 to 90 percent it would have even further delayed the project. Again, this is a development and research platform, which Sanjay himself said "if money was no object, what kind of 3d printer could you build?" By extension this means that they didn't want to compromise on the quality of the motion system, because it would negatively affect the reproducability of multi tool prints. I get that it is over engineered, but its not a platform that is meant to compete with other 3d printers. Its meant to showcase a concept by reducing introduced error from a motion system.

[@KaelumYodi]

There’s an easier trick to those T-nuts, and they should have put that in the instructions. Instead of trying to do all of them at once, just do 1 pair (1 on each side) at a time, and don’t tighten them fully, as you slide the plexiglass down the rails. Tighten them just enough so that they don’t spin. That should be much easier. :) P.S. I’d add nylon washers to prevent the plexiglass from cracking over time too.

[@boggisthecat]

Kaelum It’s a bit odd that they didn’t include washers, or a protective strip.

[@KaelumYodi]

boggisthecat yes it is. I watched a couple videos, 1 where the creator talked about it in an interview, and a bunch of red flags went through my head. While it is a product, it is actually a POC being sold as a product., without a concretely defined customer. Also, I learned why that bar was changed from carbon fiber to a machined part. It would droop when the carriage was in the middle, causing bed leveling issues that were made worse when it actually picked up a tool. It would be impossible to level it when using different types of tools.

[@boggisthecat]

Kaelum I don’t know why that bar isn’t an I or at least T bar. It does not appear to have been well thought out. Even relatively cheap large printers such as the Artillery X1 have a hefty x carriage bar to prevent flexing.

[@Geodesix]

You don't need to mess up your threads to get the tnut, just use a small neodymium magnet to pull it up to the plexi

[@Mueller3D]

If the T-nuts don't turn right, then you need to loosen them more (like a whole turn or more) first before trying again. They can't turn when they're too close to the rail. If the bolt can't reach the bottomed-out T-nut, then the bolt is too short.

[@klschofield71]

About the only thing I can agree with you on is the Bowden tube situation. It would have been more sensible for E3d to just have the amount that you need as a quantity of 1 rather than having to put in a quantity of 70 (I just put in 100 to have some extra). Although, for the purpose of full disclosure, E3d did emphatically state that this printer is not for "Noobs" and if you're not able to comprehend what you're going to need, then you shouldn't be purchasing within this platform; a point that I think you neglected to mention was the fact that E3d has presented the option of being able to purchase individual segments of all the various component within the platform.

[@tomaszbiskup891]

Question: What is the purpose of the acrylic side panels holes? What goes onto them? Anyway for this price i would expect frame with metal instead acrylic walls. Maybe an enclosed system so you can have heated chamber. Awwgh the "bowden" tube... E3D selling this as separate parts, not as complete printer, So you ordering tube by length, and 10cm is usual amount multiplicity. You have many printers and none of spare parts in form of PTFE tube ? Every time i maintain my printers and need to decouple tube i need to cut small piece because couplings cut too deep, eventually tube is too short and need to replace. In whole USA there is none of PTFE tube supplier ? PTFE is usually used in pressure systems, or better buy Capricorn tubing. Or this machine must be build whole with E3D parts?

Wait, back when Tom and Sanjay did that video and they posted this on the site it was not meant for people who are casual users of 3D printers. They clearly posted on the site that it's a development platform so you can design your own tool changer add ons and test upgrades to help the community. It's not like everyone even knew it existed so some of the complaints you made make no sense. This wasn't a Kickstarter. It was meant for people to literally design and test using the new system. I also don't think those changer parts with the tool marks on them look that great.They could have cleaned them up finish wise. By the way those Clips are called Swiss Clips they are meant for picture frames. You would find them at a frame shop. They are cheaper to order in bulk from Europe/UK.

[@waldvogelreview7755]

You are being too critical of the engineering man. If you watch the way they announced this at MRRF, they specifically said that they were overengineering the frame to make the best platform for the tool changer, kinematics, etc. This isnt just a 3D printer. Its a platform to use and abuse for tool change\multi tool head cases while the integrity of the kinematics stay intact. If your cars suspension went out of whack while working on the engine.

You've gotten so spoiled by the likes of the CR-10, the Sidewinder, and the Little Monster, you've forgotten that just a few years ago, an i3 clone could cost $1500US, or a decent- size Delta printer could easily cost $3000US. And that was with 4988s, a trash Arduino board, and barely-stiffer-than-cardboard framing. Technology moves on. This motion system will push the desktop machining world forward, whether you think it's "overbuilt" or not.

[@lgwwin]

I will pay for that if someday I want a finished printer, not my own designed one. I was building my first 3d printer in past few months, using UM2 structure with rails. To achieve the best balance between cost and accuracy, I used extrusion and carbon fiber to build the frame. And other components are Oriental Motors(mint), Hiwin Rails (brand new), NSK ballscrew(used), duet2 wifi board. Even though I live in China and easy to access to all these parts with low price, all these can go more than a thousand USD easily. Remember, my setup has no single customized steel or aluminum part yet. And this is the beginning of nightmare of assembling. I re-assembled my printer in last week, spent more than 20 hours, with 3 right angle rulers, length rulers(0.5mm accuracy), gauge blocks, and not making it perfect. It's very very hard to have two extrusions paralleled or perpendicular to each other. The extrusion cutting face is not flat or not perpendicular to its surface. The lengths of extrusions are not the same though they are supposed to be the same. Even the extrusion has a longer length on one face than the other face (difference about 20/100mm). The fasten plate is not flat, the right angle fastener has two surfaces not perpendicular to each others. In past week, when I was at home before and after work, my wife would saw an idiot hammering on a few metals slightly, a few strikes every few mins. So when I saw this E3d tool changer, the customized top and bottom plates, the holder of heat bed and the adapter of screw nut. I know it worths the price.

I was hoping that you would get one of these to give us some solid feedback on it! Looking forward to a build log/assembly and test video. Do you have any plans on getting a Railcore?

[@Underp4ntz_Gaming_Channel]

Ludicrous? dude... go look at Ultimaker.... that's $10k for plastic and 8bit crap... This thing is what people wanted... The only thing is missing (with a quick glance) is the Ball-Screw. First of all the E3D team are engineers that listen to the community... they ask their community for feedback and they listen. Why not build a printer your self. I agree with some parts but it's a 3d printer not an object you put in your living room. I'm an industrial designer and engineer myself and yes it's messy to get projects for yourself but not if it sells like burgers. If you also followed their "news" they explained why the carbon fiber sucked balls. And that's why designers should not "design" a machine and make decisions of what materials must be used. But whatever man... do your thing critics are always good even if they don't make sense. critics improve products. inventors/engineers can do whatever they can. if you work with a team you are not an engineer... just a simple cad drawer. e3d is an inventing company.

Please review when assembled! Subbed exclusively for this reason

[@hans-dieterjung4026]

Thanks for this nice video. This clips, you can find them on the back side of Pictures/painting -frames holding the glass cover

[@neuxstone]

Hans-Dieter Jung do you have a link? I can’t find them.

[@darrinbrunner6429]

I hope we get the second half soon. Thank you.

[@DesignPrototypeTest]

I'm working on it. It's definitely coming.

[@dany_2945]

your criticism is invalid, this is an overkill frame by design, from engineers to engineers or tinkeres, no corners cut, is for someone with deep pockets, it can be used for 3d printing, laser engraving, cnc, stop bitching around about the price, i get that i can't afford this, most people can't afford to buy this, for that much money you can buy a car, you should be happy that some companies are focused on the very few pro consumer market

[@KarolKrasickiKK]

Can it be enclosed and work in 100c temperature or will the components melt ?

[@infuvts]

By saying its over-engineered, you made me want to own this thing :D Oh, now I have to wait for part 2.. come on man make the next video or I am gonna come and bring you the tube on foot.

[@DesignPrototypeTest]

I'm currently printing the test prints for the end of the video. The video will be released shortly.

[@infuvts]

​@@DesignPrototypeTest Nice!. So far your videos have been really helpful. I got Tevo little monster and after step by step following your conversion video, I managed to do it. Wouldn't even try if it wasn't for you, so thanks!. Then I got brave and installed the smart effector and zesty nimble, it was messy, my room full of bolts and tools, but now I am in love with the setup and I got a taste for building machines, even just for the sake of building em. And I decided to plan year ahead and go for a CoreXY tool changing printer. I searched KZbin and found your video. Ha, ha, nice, you are back with a big bang.

[@neuxstone]

I like your videos but...all the crying about the Bowden tube...Amazon will get a Capricorn to you next day which you should have anyway. I always keep spare around. Second, I wholeheartedly agree about the CNC and the price they pass on to the consumer who has no say. Product design engineer is what they needed. They’re basically selling a machine in the “prototype” stages to anyone willing to pay. I’m not star struck over E3D products so I wouldn’t purchase one but I liked your video sometime back about the guy who built his own as you showcased it.

[@neuxstone]

Agree

[@Thomas-qr3bg]

How big is the print build on this machine?

[@misiukowalski5653]

Yea a lot of complaining lol. I only watched like 5 minutes, but like for example the carbon fiber top argument that's about it being lighter and less rigid...that's the point why it's made from metal, to be more rigid with better cut tolerances. Idk, even my grandma complains less lol

[@timothyreyes5392]

Am I one of those guys no longer using T nuts??? xD used them 3 years ago never went back decided to 3d print adapters for the aluminum extrusion just placed regular nuts or square nuts

[@thinkright]

Drool. Very nice, can't wait to see it in action.

[@ConstantijnC]

I'm so jealous! And I understand your frustration but except for the price, that thing has more sex appeal than my girlfriend...

[@SebastienChedalBornu]

Openbuilds use better tnuts, you just have to put them inside first.

[@albion115]

Thanks got helping b is for build!!!! You just got another sub

[@SebastienChedalBornu]

Do you have the reference of the stepper motor installed in the change tool to lock it?

[@JimPBarber]

Ok, now this is just 3D Printing Porn!!!! I went some weeks back and filled up my cart and cringed at the final price.... Was ready to hit the button when my wife came in and put the hammer down! Jezsh.... You would have thought I was having an affair with her reaction.... Long and short is I will have to live vicariously.......

[@ElvIsAlive007]

when are you going to review the railcore 300xl printer mate !!!!

[@DesignPrototypeTest]

When railcore sends me one. I have all the printers I need, and review videos don't even earn me enough money to pay for the printer let alone pay me for my time. For example, this video has earned me $106.81. Railcore doesn't give printers to reviewers. That's a mistake. Then again, maybe they are selling as many printers as they want to, and they don't need the press.

[@RonSayss]

Nice

[@azdronedude]

Do you recommend buying this very expensive solution?

[@DesignPrototypeTest]

It's currently the only solution on the market. It works well. It's about 2x too expensive. If you need this functionality this is your only option. Then again, the Palette 2 might work for you.

[@tinusblaauw4092]

Nice video - what product is this exactly? I've gone onto e3d's site (unless I got the wrong one, which may also be!) but couldn't find this printer as a kit? :)

[@DesignPrototypeTest]

You can't buy it on the site. You have to purchase a place in line. When your number comes up, you get an email with instruction on how to order all the components (~$3,500 USD total). Here is the link for that: e3d-online.com/tool-changer-join-the-queue

[@schano1992]

Don't wanna sound rude but you tighten the t nuts a bit and slide the part into the frame I think ^^!?

[@DesignPrototypeTest]

You don't sound rude. Thank you for the input. The T-nuts can certainly be installed in this manner, but it is a PITA to do so. It would involve removing the top or bottom plates to access the ends of the T-slots. Also, the T-nuts are designed to rotate into place. Sliding them into place defeats the convenient design. E3D should have spec'd slightly longer bolts.

[@schano1992]

@@DesignPrototypeTest had kind of this problems on assembling an cheap kit personally I have made the best results by tighten the nuts completely and then lose them until the wings can move in the extrusion then tight them back down... Just use nails :D btw great video share your opinions in most cases keep going

[@msdesignru]

Pretty interesting kit to play with!

[@codeman0018]

Hypercube evo is great

[@jhijhi85]

the last version of Duet has an external antena

[@andrewjamez]

So your initial price included all the tool changers? And electronics?

[@mechabits197]

Designer buys another printer....you sure seems to like other peoples stuff more than your own, a magnet on your hex key might have got those nuts sorted, surprised you needed the instructions

[@RomanoPRODUCTION]

I leave a nice commentary for a proper video and a nice kid

[@certified-forklifter]

15:54 is it me or are these ics absolutely bad soldered? there are all shorted out?!

[@FireN2k9]

Good Question, in the video before they were soldered differently ^^

[@certified-forklifter]

@@FireN2k9 yeah strange. maybe they make it to have a better heat transportation to the pcb and the short circuit doesn't matter, maybe v2 or so

[@FireN2k9]

@@certified-forklifter If not, the magic smoke comes out :D

[@certified-forklifter]

@@FireN2k9 lol, excited for the new video: "i turned my 4k machine on and my house burnt down" =D good luck design prototype test

[@jhijhi85]

what stepper motors do you have on that printer?

[@jonathank1723]

Lit

[@LuckyX0182]

do they also sell electronics as kit or how did you now what electronics you will use?

[@DesignPrototypeTest]

To get this printer you pay £120 for a spot in the queue. Once your queue number comes up they send you an email to a one-time hidden web page that only you can access. It is here that you can order all these components. The website tells what to buy to complete your kit The wording they use is "recommended" but it means 'This is a required item for this build'. The website has all of the items I showed in the video.

[@chriss2295]

You have no appreciation for the engineering that went into this. Time is money. It’s so easy to be critical. Not so easy to create a working platform as this. If you don’t like it, design something better and put it out there in the opensource space.

[@ronnieglendinning]

hard to watch

[@vonsyp]

Hi thanks for sharing 😀 may i know what is the dimension of the bed ? Thank you

[@fbujold]

The R&D that this company makes justifies the price. Also don't forget that this is open source. Which implies that every dick and harry will copy and sell this for a fraction of the price without E3D getting any retribution. If you want to promote intellectual property and fairness and ethics, well... you know what to do. And BTW if you are not happy with the design, it being open source, branch it and make this world a better place. Quality has a price.

[@mleitner0]

Call me when its pre assembled and 1k max.

well i bet that frame is open sourced! and im willing to bet my life it could be built to exact specs for far far far far far far far far less! i mean wtf 1,700 euro's?? thats like 3,000 canadian! fml i wanted this machine but for that price and all you get is a god dam fucking frame!.....fuck that noise

kinda Meh tbh, for all that money perhaps you could build something better
