In this topic, we would like to gather all general questions and suggestions about everything to do with plastic sheets and sheet-presses as well as providing you with an index and links to all topics concerning specific aspects of sheets, sheet processing and sheet-press development. The structure is intended as shown in the picture.

Hey everyone! Six months in and we have our first working prototype of the sheet pressing system up and running! Below is a presentation which highlights the journey so far and a video of the process so you guys can give us some feedback!
Not exactly sure if it is the same as thermoforming or not, but vacuum forming is very easy to do (assuming we can produce thin enough sheets of plastic), so that may be good to pursue.
Lovin the sheetpress you made!
This got me wondering if there is a list available to reproduce the SheetPress ?
For instance These;
Good ideas, although I’m a bit sceptical towards both.
fot thermo forming I think you need a very consistant output and thus very pure input material without any pollutions.
for simmering I worry about warpage and thickness deviations.
but for both, only 1 way to find out! 😁
I you try so, let me know, otherwise, maybe @v-varella would like to try
Another Idea of mine was to take the thicker sheets produced by the sheet press, and let them “simmer” on a large griddle to alow them to heat treat (for more strength + transparency) and for the sheet to be thinner.
This could be a really valuable part of the Precious plastic toolkit. It opens lots of doors.
Is there a development timeline somewhere for this / V4 in general? Or an informal estimate on when this might be available and the cost to make it.
@markbertbach I just came across your thesis work in the other thread https://davehakkens.nl/community/forums/topic/plastic-plate-press-semi-diy-semi-professional/ . Maybe you should add it to your index, perhaps as background information. It really is a valuable resource and should be visible.
Thanks for the great work
@martink, a short look at the oven drawings; i’d say 2 skilled metal workers can do it in 10 – 20 days, assuming CNC or at least guided hand plasma cutter or metal brake machine, in top of the normal tools, 20-30 sqm space; less than that, eg: alone & not all tools : 1-2 months. transport in EU easily in thousands (2*2*2m). if you would build this your self, possibly 2000 – 4000 Euro. that’s just the oven and the estimate is a for 1:1 copy. there are quite some shortcuts you can do but I guess most the parts have to be there or at least done like that. Evtl. this goes much cheaper in bulk from a laser service …
Well done guys! I can’t wait to start making sheets, going to be nice to see what comes with v4!
