SPR - 2.3

by Precious Plastic Nantes

The Sheetpress presses plastic into recycled sheets. This machine can make multiple sheets per day, recycling up to 50kg of plastic per sheet.

This model of the Sheet Press System (2.3) solves 3 main problems: Safety, transportability and standard sheets dimensions. How? By following the CE safety requirements (European standards), designing it to be easily disassembled to be flat packed and having bigger heating beds to make 1.2 x 1.2 m sheets.

In this how-to you'll find the download files and the requirements to build and run this machine yourself :) —

    Step 1 - Download package

    First off, click onthe Download link above to go to all the files for this machine!

    In this folder you will find:
    - 3D CAD (.step and .f3d)
    - Lasercut files (.dxf)
    - Blueprints (.pdf)
    - Schematics
    - BOM
    .. and more :)

    You can see a preview of all the files (in case you are just curious 👀) and you'll also be able to download them for manufacturing 🔧

    Step 2 - Build

    There are a few required skills and machinery you'll need to have if you’re building this machine yourself, or for the machine builder if you are asking someone else to build it for you:

    - General metalworking (cutting, drilling)
    - Welding
    - Turning (machining on a lathe)
    - Milling (machining on a mill)
    - Laser cutting
    - General electrical work (wiring safety switch, temperature controllers…)
    - Motor electrical work (wiring motor, contactor, overload protection…)
    - Programming (PID, VFD…)
    - Advanced assembly work (require specific tools, measurement instruments and tolerances knowledge to align and assemble)
    - Pneumatic
    - Hydraulic
    - Painting

    ⚙️ Machinery / specific tools needed:
    - Grinder, chop saw, MIG/MAG or TIG, drill press
    - Lathe and milling machine (can be manual)
    - Laser cutting (this can easily be subcontracted around the world)
    - Torque wrench and bearing mounting tool

    Step 3 - Run, Maintain, Create and Sell :)

    To run and maintain this machine properly and safely, make sure to have a look at its MANUAL:
