I've also made some silicone molds directly on the 3D printer. Some of the things I do, put through holes on the mold blocks, so I can use all-thread, nuts, and washers to clamp down the mold halves, fourths etc. Next, I have a bunch of super sculpey clay, and I find the pink clay rolled into a thin bead, line it across the inside seams of the molds, clamp down, then come in with a finger, paper towel, clay sculpting tool, whatever to scrap out the excess clay. Obviously some sand paper, solvents, and finishes all will improve quality depending on what standards you are looking for, but not always required.
Your like an old version of me. I’m a Machinist from the Chicago area, I use inventor at home and solid works at my day job. I’m here investigating possibly making a custom o ring.
I've been working on silicone gasket moulds all week and now I feel like Eric can read minds... XD Great vid by the way, really useful for my project. Thanks!
Eric, first of all, I'm very impressed by your Fusion skills. I do have to say that it seemed like your 3d printer was letting you down a little. I'm currently using a Prusa MK3 and the magnetic heated flexing bed has been great for prints like the one you did. Nowadays, I print PLA, ABS and lots of PETG and I just don't have the artifacts or need to apply any solvents/glue stick for bed adhesion. I'm certainly not a 3D printing expert but moving on from the borosilicate print bed has been great. You have a process that works well for you but it might be worth a test drive to see if it helps your workflow.
Some of the older videos did not translate well when uploaded to RUclips, music is a bit much on some of them, I wish that this was an editable thing, unfortunately it is not at this time
Since the gasket is thicker on one side that the other, I assume the orientation is important. Did you consider adding something to the mold to help orient it, like a tab or notch? If you had to make another one, would you add something to the exterior of the mold to make it easier to unscrew them?
I printed some silicone part molds earlier this year and was genuinely surprised it worked as well as it did. Apparently there can be some barriers to curing silicone around 3d printed parts but i haven't had issues yet.
how critical is the vacuum chamber? and is that a DIYable project? looks like a well-sealed bucket and a pump? And how critical is the heat-curing or is that *only* to make it faster? great videos, thanks!

Thanks for the feedback
thx for the info, just a quick comment, the music is a little intense...I had to turn it down or off in between...

Great Video Eric, Thanks for sharing. the level of detail is impressive.
Info 10/10
Music 20/10
Great info and Great music ,Cheers.
Quick question... Why no register the gasket as to always place it properly on the gasket holder?
Awesome Channel! #FULLSUPPORT Also love the choice in music!

Yes
I love your videos, thanks
Hello
can someone advise me what are the characteristics of the vacuum pump used to get the bubles out?
I printed some silicone part molds earlier this year and was genuinely surprised it worked as well as it did. Apparently there can be some barriers to curing silicone around 3d printed parts but i haven't had issues yet.
i think thats mainly sla resins and then you should use tin cure silicones instead of platinum cure (platinum will have serious inhibition issiues)
Anyone knows what song is playing at 04:58? Nice vibe for modeling.
What type of silicone are you using? Edit: btw, this video is gold. Subscribed
Silicone inc 1040
if you are about to make many of these you better redesign the bottom part to make it easier to open by hand
You made the Germs logo!
Hey man, it's been years! Tell us where the part goes! 😊😊
Shower drain if I remember correctly
how critical is the vacuum chamber? and is that a DIYable project? looks like a well-sealed bucket and a pump? And how critical is the heat-curing or is that *only* to make it faster? great videos, thanks!
Neither are critical they just give you better results
maybe 3d print grip tabs to grab and make it easy to open?
Very neat - I am sad that I have no need for any silicone parts, it looks very satisfying to make those :-)
Hey Eric how do I print something for my kayak
Great video. Interesting to see Fusion 360 design process. Mahalo for sharing! : )
You bet!
That shit doesn't help dude...
