As part of our research into suitable materials to use for building our 3D Printers such as the Huxley Seedling we discovered a number of advantages and disadvantages between using Acrylic Perspex, Plywood and MDF. Quite simply …
Benefits of using Acrylic Perspex over Plywood and MDF
- Acrylic perspex gave improved accuracy due to warping of Plywood. Even high quality laser Plywood and MDF had slight warping (>0.5mm)
- It looks far better than wood.
Disadvantages of using Acrylic Perspex over Plywood and MDF
- Cost of Acrylic Perspex is usually more than twice the price of Plywood and 3 times the price of MDF.
- Cost of laser cutting is also more for Acrylic Perspex as it takes longer to laser cut than MDF and Plywood.
In our tests we used 3, 4 & 6mm MDF, and 3, 6 & 10 mm Acrylic
We discovered that 6 mm Acrylic Perspex or 4 or 6 mm MDF was the most robust and best suited to our design and assembly using Fixit blocks for the 3D Printer frame, whereas 10 mm Acrylic Perspex was well suited for making 3D Printer print beds.
As a result we offer two variations of 3D Printer kits using mainly 6mm & 10mm Acrylic Perspex or 4 or 6mm MDF.
