[@tristandumoulin4011]

I've been watching DIY / automation / manufacturing / crafting videos for the better part of a decade and must admit you have the best quality output I have ever seen.

[@PatrickHoodDaniel]

When I see you put out a video, I get so excited!

[@RTAFabrication]

Thank you man! I appreciate the continued support and hope you enjoyed the video!

[@davijayakumar9181]

This is the best video I've seen for showcasing the product development process.

[@DF999]

I need more videos. Your work across the cinematography parts to the actual content is so insanely good I’ve binged your whole channel in a day. This stuff is making me really want to dive deeper into this world beyond just 3D printing.

[@goober-ll1wx]

Your attention to detail makes my OCD very happy 🙏

[@ibcharles]

the amount of work you do is so worth it for when you open it, that 1st part reveal was beautiful. excellent videos and work.

[@_IanOfEarth]

This series is already a treasure trove, going to be a true masterclass once it ships.

[@jorbedo]

Brother, this is the best video in terms of quality and the amount of information about prototypes/short production. Excellent, thanks for sharing!

[@zxcaaq]

Mashallah this is true artistry, love all your videos. Keep making more!! and I love your calmness.

[@lifeholdstrategic]

As many have stated, thank you for the time that you put into these videos. @ericstrebel does similar small batch production and prototyping and it’s cool to see you both working through the process.

[@khashayarr]

Absolute joy to watch your process! Learning a lot! Also, thank you so much for not adding background music. It's how instructional material should be! Looking forward to watching more of your work

[@RTAFabrication]

Thank you! I’m glad you’re enjoying the videos and they’re helpful to you! Yes I agree, videos like these where information is being conveyed really doesn’t need any music. Thank you again for watching!

[@ИгорьМилюкевич]

Мне нравится стиль твоих видео, как ты работаешь над каждым кадром и подсъемами! Отличная работа с освещением! Педантичный подход к проектам. За это я и люблю твои видео и радуюсь, когда выходит новое видео!

[@TheHanutaXD]

Everything you do looks so clean and cinematic. But please wear a mask when sanding polymers, especially when using carbon fiber mixin :)

[@FlameLenses]

Your thoughts and approach are outstanding, my friend. I have been working in this field for 9 years, and creating an ideal product requires time, effort, and patience. You are amazing.

[@markusgri]

Wow, not only the style of making this videos like cinematic looking, also the logic behind the processes and how something is done is just amazing. I am always hyped to see your new videos! Normaly i am not the guy who comments. But in that case i want to push your videos, support you and want to say thanks for this high quality making videos. Best regards from germany!

[@charlesgreig]

I’ve said it before and I’ll say it again, your videos are art mate. I’ve really enjoyed the process, and whilst I’m intrigued to see how this pans out, I’m already imagining what’s coming next? You could make almost anything with your skills! (Also, I hope people/companies who make machines are watching your content and thinking ‘we should send this guy one of our 5axis cnc’s’ or whatever, would be worth it for them!)

[@karolrosiek5674]

Very well described step-by-step method and well edited material. I look forward to more videos like this :)

[@z3ejay]

Thank you for making these videos. They provide valuable insight into production at scale.

[@GaryMcKinnonUFO]

Nice process, i only make coasters and coaster holders at the moment and 3d print a positive master mould, then coat that in epoxy resin to give it a smooth and shiny surface, then pour silicone rubber into that to make the negative mould, then use resin to make the final part.

[@alexon2010]

Dude, your videos are amazing, they make my head spin, understanding the relationship between these models... but fantastic work.

[@h4z4rd42]

As a movie prop maker all I can say your dedication and skills are outstanding. Also, the quality of your video is extraordinary. I wish I could have you in my crew. Oh, and you got a new subscriber. Keep on the good work!

As always - so inspiring and make me want to learn more about casting and sla printing. Thanks for sharing your journey.

[@ivanvarovin176]

I've made a lot of molds in my life, also quite complicated ones, but I have never used an approach like this and never even thought that it could be done like this. Thank you for that awesome idea. I'm definitely going to try it someday and I'm going to advise some of my fellow ex-colleagues to try it out also.

[@RyanPourcillie]

Really enjoy watching the thought you put into every video and every project. Professional across all mediums you work in. I'm hoping to follow your lead in creating my own molds for some multi-part products I've been 3D printing until now. Seeing your detailed process has already given me a whole picture of things I would have missed or made mistakes on before even starting.

[@DominusFeles]

This is pure relaxation for my brain.

[@picassoimpaler3243]

Stoked to get my hands on one of these if i can afford it lol. I do very similar stuff in one offs for custom vehicle interiors. Using these work flows is a pretty niche world, so its cool to see other peoples design and production processes.

[@turbeau405]

Nice upgrade to the work flow.

[@75keg75]

On Robert Tolone channel he has a few tips n trick with silicone that maybe of interest. Mould preservation etc. using positive pressure in some cases to pop bubbles. The other channel that may be worthwhile is “out of darts”. The workshop tours the guy has done have some scaling tips. There are 3 or 4 so far, the first couple he mentioned a couple of books that talk about efficiency of work flow. As a result he came up with magnetic jig that held the magnets that were inserted in the nerf guns. He quickly gets a magnet, holds near jig, it attached to jig magnet (glued) then the pulls the arbour press handle to inset four magnets at a time. It took seconds instead of minutes. He has other things about order of operations and setup of workspace to maximize time saving. Less walking is more production sort of stuff. A high tea style rack that you load and you drop into the vacuum chamber would be handy - saves you having to reach down into the chamber with wet resin. That could spill. Time efficiency is critical. Anything you can do to speed up workflow is more profit…

[@C-M-E]

A quote I wish I had come up with: 'Necessity is the mother of all invention", with perhaps my own footnote, "THEN you refine your options." This is a textbook example of prototypes versus production though. Waiting until you get into injection molding. 👍

[@cruzmou]

Your work is outstanding dude, love how you approach every single part of the process of it. CCCCongrats!! Keep it up!

[@JS-vk7ek]

Hearing you talking about casting a tube within the casting sounds interesting. But I wanted to highlight that this is an issue if it goes anywhere near the pressure tank (in case you had not thought about it, which I am sure you have). Love this video. I am "trying" to create a cast product, and it takes all my time to concentrate on this, let alone your detailed video setups. I have no idea how you manage all these workflows at once. Well done to you; the video and the productions look amazing. First time here, but subscribing and diving into the archive.

[@BasicFolders]

The amount of time you make us hold our breath each time waiting for your next video is just cruel. 😂❤

[@HaasGrotesk]

As always it's so enjoyable watching you work. A master at your craft. And as always I learn something new everytime. Also the cinematography is way too good for a KZbin channel! You should make movies!

[@monsterclosetcom]

I call this positive halves with the dividing wall(s) “inverse molds.” Used this several times and always amazed when the poured halves fit so precisely together.

[@tertiuskammeyer343]

I am pleasantly surprised it worked that well (likely due the compliance in the silicone when clamped and contained in ridged braces) From previous experience, it’s never as tight and clean as doing two castings with one master.

Could you dive deeper into the resin printing side of things. Seeing how easy your prints come off it looks like your settings are dialed in really well.

[@MattDamonAMA]

This video helped me fall asleep.

[@RTAFabrication]

Fantastic!

[@MrMartinbauer]

Great work and passion! What about the problem of platium-silicon does not cure/inhibit problem with resin-printed forms? You did't seal your forms ... so maybe your resin material does not have that issue? Whoch material are you using? Or is it just like magic ...

[@RTAFabrication]

Hey, thanks for watching! A fair few people have asked about this, so I’ve posted my reply to them below as it’s relevant to the question you have. “It’s funny, I’ve had a fair few comments about this, and ironically I had a whole section in this video mentioning it which I removed which I’m now regretting! I only removed it due to the length of the video. This is something I get asked about a lot. Weirdly this is never an issue I’ve ever faced. I’ll always either use the Mann Ease Release 200 spray on mould release or I’d paint the master. Both create a barrier between the print itself and the silicone. On the multi cavity mould with the 4 masters built in, I didn’t actually spray mould release on it as a test to definitively see if I’d get any cure inhibition. As you saw, I had no cure inhibitions which surprised me! I went on to say that I’m not sure if it’s down to the SLA resins I use, or the silicone, or the cure settings, or time after curing the part and moulding. I’ve had many people say they use the same SLA resins and have had issues, so my best guess would be that it’s the platinum silicone. The resins in the video were from HeyGears, the PAWR10 is the beige/ creamy colour and the PAU10 is the grey resin. I have an Elegoo Saturn 2 8K which I usually use AnyCubic ABS like with 10% Siraya Tech Tenacious mixed in. I’ve never had any cure inhibitions with any of those resins. The silicone I used in this video is a sample of a silicone I’ll be releasing soon. I also said in the clip that I cut that I might do some thorough testing to try and get cure inhibitions so I’m able to figure out which variable is enabling me to do this to try help others out. I hope that’s helpful in some way and thanks for watching!”

Amazing work! did you just use regular platinum silicone on the resin prints without having any cure inhibition?

Yes, the extra time you put in at the front end always pays off. I've memorized all of my important numbers. You wouldn't believe how convenient it is to just rattle off your bank account number, rather than go digging for your checkbook.

[@RTAFabrication]

Thank you man! Really appreciate that! It’s been so nice not having to do mould prep with clay and barrier’s to make a new mould. Really happy with that system. As I said in the video, the extra work upfront will reduce any friction in creating multiple moulds. Wish you the best too man and thank you for watching!

Must be a damn good feeling when so many orders are coming in that you need to optimize production workflow. Can you say what type of urethane resin you're using for the cast parts? I've never had any luck casting urethane without a pressure pot.

How do you make a mold of something with a thin wall thickness, has a specific shape. Does clay play a role?

[@adamchambers7502]

Hey, whats the advantage of making the silicon inserts for inside your mould shells for moulding the finished pu parts? Surely thats a carryover from the days of making a replica of a physical part to mould from? in this case, you are a skilled CAD operator, you can design the parts to get you perfect mould negative cad parts, and you have a hi def resin printer, so you can print your moulds...why not just mould directly the Polyeurethane into a printed resin mould? Ill level with you, I'm fishing for information. I'm a mechanical engineer moonlighting as a product design engineer in my current role at work....i don't have the greatest amount of experience moulding TPU (although i ve printed hundreds of go pro mounts in it on my side hustle at home), and ive taken it upon myself to redesign a safety lanyard for something that i intend to make out of polyurethane 6-90A (not sure yet) Theres no way i have time to go to the absolute fine detail you are doing, and i didnt buy any silicone, just a bunch of different PU grades from smooth-on. I am simply prototyping to ascertain the best grade of PU to use, and size /strength test my critical features, but i am simply planning to print the mould negatives on our resin printer in 2 halves and pour directly into it (well actually i purchased a massive syringe to do it, so i am definitely intrigued with your simple pour method).

[@markirwin3624]

Let's say I have an FDM printer. Would I be able to make it work with this? If so, then how so?

[@RTAFabrication]

Yeah absolutely. I’ve printed some FDM matrix mould shells. I haven’t done this exact setup with the masters built in, but I have done it with clay in the example I mentioned towards the beginning. I’d suggest watching the video I did on moulding the oak plaques. I use FDM printed shells in that video showing the exact process. The one thing I like to do with the FDM prints is coat the interior of the shells with a brush on epoxy, like the XCR resin from Easy Composites. This just gives the shell a smooth surface for the silicone to take an impression of rather than it picking up all the layer lines from the print. This is just an extra step I like to take to ensure that the silicone seats back into the shell well.
