Casting Wax with 3D Printed Molds

In this video I'm doing some experiments to see how you can use 3d printing to make molds to cast wax into different shapes.

i like your approach and humility, mixed with intelligence and precision

[@knartfocker_]

That dyed look turned out great.

[@ramwoodburns2225]

You can never have enough skate wax. Also a great option to reuse old candles in the house. At some point I'll have to order 2 of them skate wax one for skateboarding and the other for my wood shop. Us hand tool guys always wax our hand planes and panel saws. Really dig your diy videos they make me realise how badly I need a 3d printer in my life.

[@GoodRoads]

I've gotten pretty far away from the hand tool work over the past few years but I'd love to get back into it. All my gear needs a tune up

[@birkansevinch3095]

Great job! Thanks for.

[@WaffleStaffel]

Wow, the vernacular transports me back to the 90's.

[@PhoenixPerryisawesome]

You can coat your mould with petroleum jelly I think it remove it easier - saw this when I was looking at something related but it has been years.

[@CodyKhaoz]

this is super dope!!!

[@edstar83]

It's rad dude. kzbin.info/www/bejne/hKXYfqKGac-Dlc0

[@deopersad2915]

Awesome 👍🏻👍🏽

[@ahmedh2766]

Thank you very much for sharing such a great video. This is an experiment I have wanted to carry out for some time but you beat me to it xD. I wanted to ask you some questions as you have experience with casting including metals. The casted wax parts made, are they suitable for investment casting/lost wax casting to convert to lets aluminium. Is there any chance you can make thin wall parts to really test limits, or a complex 2 part mold, should you require designs please let me know. Looking forward.to your reply.

[@GoodRoads]

I did some super rudimentary lost-PLA casting this Christmas, but I didn't even burn out the plastic and the results were only okay: kzbin.info/www/bejne/m3XOcodriamHjZI I haven't done any lost wax or PLA casting outside of that but I do want to try my hand at it in the future

[@jimmypham2487]

That’s cool

[@enzofederspiel6570]

Love it

[@SK-me9by]

Which TPU filament did you use?

[@jenniec.6951]

What material are the molds made of? PLA? And you try in FEX?

[@023douwebakker]

He uses TPU for the flexible ones

[@Andelu7]

I've been playing around with molds as well. I was hoping to do some clear resin jewelry but the resin really picks up those layer lines. Even printed at 0.16mm. Have you tried clear resin yet?

[@GoodRoads]

The only resins I've poured into 3d printed molds were the urethane rubbers I used to make skateboard wheels. Without pigment they're sort of a clear amber color and I was able to get the surfaces pretty nice but I had to do a ton of post-processing on the mold first

[@danw.7935]

You'll probably need an sla or something to get higher resolutions that don't have layer lines (at least not too discernable). I'm printing wax injection molds with an sla printer. I have a mars 3. Incredible resolution, but so far the molds are pretty rigid so I'm doing 2 or 3 part molds and then run against the issue of parting lines.. Alternatively, prio to printing the molds directly I was casting the molds from 3d printed parts into a 2 part clear silicone solution. Those molds are pretty good and no layer lines, I'm just trying to reduce steps.

[@danw.7935]

Also, they do make flexible resin for sla printers, so that's probably my next step. Anyway, you're probably running up to the limit of what an fdm can do in this space

I've always wondered about reusing scraped wax from my snowboard. It always seems like a waste to throw it away.

[@GoodRoads]

Oh that's a really good idea!

[@InformatrIIcks]

When done properly there's very little wax that need to be scrapped of ... You'll need to have a jar of "old snowboard wax" laying around for anything significant 😂

[@GoodRoads]

I'll put that jar right next to my "failed prints to figure out how to recycle" box and my "scrap wood that you could probably still use for something" bin

[@InformatrIIcks]

@@GoodRoads i'll save you a jar and the hassle : recycling failed 3d prints just isn't worth it. So use the jar for the wax. Source : some friends of mine work at airbus (one of the 2 big airplane manufacturer), and their R&D dept produce a shit ton of print per year, they looked into recycling them. So they had their plasturgists trying to figure out something, bit the problem is that plastic degrades each time it's melted. So you're taking pellets, that you melt into filament, that you melt into a print, that you melt again in filament to melt into a final print ... Way too much plastic degradation. They concluded that they would need additives + a significant part of new material to create new filament that behave properly. Some people on youtube had some success with trying to recycle filaments ... It feels like too much work if your endgame is to print practical stuff. If 3d printing is a hobby, then maybe it could work. But for Airbus, me, and quite probably you as well, 3d printing is a mean to an end, which is the printed part. In those circumstances I don't think diy recycled filaments are worth it. Final point : I bought some industrial recycled filaments (had a discount for 9€/kg). I can only reliably print it through a 0.8mm nozzle, otherwise i get clogs in ~2h, that are pretty normal with the recycling process ...

[@ideogramnl]

If snowboard wax is the same as ski-wax, you might want to research this idea a bit more. Ski-wax might contain PFAS. I don't think you want to burn those indoors and inhale them. I'm no expert on this, so please, do your own research.

[@stillpointx2623]

What type of hinge did you use at? kzbin.info/www/bejne/lZDEaXiMit2aaZY

[@Marcresus]

Why don’t you use silicone mold, is there a difference ?

[@laraelnourr]

What about ABS or PETG?

[@SK-me9by]

A Flexible filament is best unless you make a two part mold. Make sure what ever filament you choose can handle the heated wax without warping.

[@AckzaTV]

But also, tjhey have wax filaments for 3d printers lol u can just print the wax. of course this looks cheaper lol but still if u wanna do super good acurate shit cheap too u can just get cheap $100 resin printer and get wax resin and make actual pro grade jewlery, of course u know that but ya i wonder, where can we get lots of cheap wax for practicing this? i was thinking about all the wax i get whenever i freakin buy certain brands of HEESE wheels!!! i KNEW I wouldl ned it one day :D its red tho,m think thatl be an issue?

[@OverlordRylin]

You probably poured your wax way to hot. I noticed you're not using a thermometer and that is a big no no woth wax. Also never ever put wax in a freezer because it can make it brittle.

[@GoodRoads]

Thanks for the tips!

[@ideogramnl]

That's easy to prevent, isn't it? Candle wax melts below the boiling point of water. So, melt the candle wax 'bain-marie' (double boiler, heated bath) and the wax will be much cooler, so it won't wrack the PLA.
