The Mayku FormBox is compatible with a range of materials and thicknesses. For a full list of materials and thicknesses, please visit the Mayku Materials page.

The FormBox works really well with thermo-plastics (plastics that go soft when warm). Here’s the technical terms for these:

• Acrylonitrile Butadiene Styrene ABS (the stuff Lego is made from)
• Polystyrene PS (Product packaging)
• Polycarbonate PC (Drinks bottles) *
• Polypropylene PP (Buckets, spades, chairs, everything!)
• Polyethylene (sheet and foamed sheet)
• PE (Insulating cases, bottles)
• Polyvinyl Chloride PVC (straws, plastic pipes)
• Acrylic PMMA (Light up signs)

*Note: PC absorbs moisture that bubbles up when heated and requires pre-baking. You can dry out PC in an oven at around 90-120 degrees C for 6-12 hours (the longer the better), testing is required on a case by case basis.

How do I know when my sheet is ready?

The FormBox heating controls are set for the Mayku sheets and recommended temperature settings are on the material box as a guide.

However, there are no hard and fast rules as to how long this should take, so experiment with different times and temperatures to find what works best for your tool shape and environment as the ambient temperature can play a part when heating the material. Look for when the material just starts to bow and bring both trays down over your tool.

Wait 15 seconds after you've formed your object to allow it to cool down, then remove from the bed.
