Sheetpress v4 -Fiction Factory version
We have build the sheetpress system with some upgrades which we believe are worth sharing! In short:
- Shared our labour hours for realistic price estimation
- Making all sheets & parts suitable for lasercutting and sheet metal bending
- Updated the bom-list
- Made changes to the circuit diagram
See files below for more information

Step 1 - See document: Updates V4-FF
- The updates we did
- We explain the problems we encountered during building
- Also we shared the hours we put into the build with an estimation of the cost price if you will make the machine commercial
- We propose further future improvements which can be done
Displayed picture: The biggest hickup we encountered during building was that we underestimated how important it was to ream the holes of the aluminium blocks to the exact measurements.
After chatting on Discord with "truth-teller", we reamed the holes to 11.95mm, followed by heating the blocks to 250 degrees (making the hole temporarily bigger) and pressure fit the heating element in to the holes.
Step 2 - See CAD files
Step 3 - See electric & BOM diagram
Also we added a kWh meter which can set to zero when you start your day melting plates! This way you can track the electricity needed, and thereafter calculate this to a Co2 load for a plate of plastic.
We added signal lights on each group and old ceramic fuses. The signal lights gives visual feedback when a heatign group is active. The ceramic fuses protect the heating goups in case of a short circuit. We discovered ceramic is needed since they can get a bit hot.
Step 4 - Making plastic Precious again!
The first commercial client where we used our machine for is The Student Hotel in Delft. Thet wanted a sustainable circular design for their interior. From post-production HDPE plastic we made the black&white cladding of their bar. The client wanted us to incoporate their waste streams which where mainly (HDPE) bottle-caps from soda bottles. The caps are melted in to the plate's.
