Hi, great job. I do similar stuff for rc cars, my advice is less sagging of the material and more pulling / stretching of the material by the vacuum. Mostly sagging is only 1/3 of the model height.
Heat the mold first! You should make a cavity on the bottom .(guessing) but cut out a 3"x 5" hole in the center of the wood that is attached to your mold. Then drill your fine tune holes to that cavity . That will give you extra pulling power plus heating the mold first helps a bunch because when you drop the sagging plastic on a cold mold it cools it to fast trapping unwanted air. Hope this helps you!
Christian Lewis Many will use painted wood molds that are sanded and painted with a few matte layers to get a very smooth finish. Non ferrous molds work the best but will set you back a considerable cost.
ahojte , také jsem něco zkoušel a zatim sem se nepřiblížil ani trochu k jednom z vašich testů , takze vysledky mam 00nic , mohly by ste mě poradit co můžu dělat blbě , popřípadě kde by sme to probraly ? fb ? mail ? děkuji vám moc
Where can you buy those acrylic sheets (PMMA)? , or plexiglass in the market? that are thermoformable. Is there a link or website to buy online? Thank you very much for the help, best regards
What are the dimensions of this unit? What is the material you are using at 1:56 to form the heater box? I am guessing it is some sort of ceramic. Did you find that there were any leaks when you use wood in the vacuum box?
Not in my experience. It does form little bubbles though. PETG is also easier to work with than polycarbonate (Lexan) due to the lower moulding temperature of around 125C vs 190C.
Stick around!
The ending design and Test results are MUCH MUCH BETTER!
I Like it!!

Hello.
Thank you for the advice. We'll keep trying.
very good idea. Thank you.
Thank you for sharing ! Merci monsieur. I may thy some days . J'' essayerais bien un jour mais pas sûr et pas évidant .
I love your setup, I’m taking ideas that people have and just seeing trial and error. Any notes you’d change after using it for a while?
Ótimo grande projeto!...
Is 10 mil ( .25mm ) polyester film okay for forming and will a 3D print of PLA work for the form?
Nice n clean build
Really cool work , Let me paint the van XD
Do you make your patterns out of plaster? Do they leave a perfectly smooth surface on clear plastic? Thanks

Hello,may i ask the vacuum pressure is?

Where’s the little holes you have to have in the mold? They go in inconspicuous spots and it gives you a deeper pull
Does clear PETG turn white when over heated?
Not in my experience. It does form little bubbles though. PETG is also easier to work with than polycarbonate (Lexan) due to the lower moulding temperature of around 125C vs 190C.
Great information
