The Mayku FormBox works best with thermoplastic sheets, in thicknesses ranging from 0.25mm - 1.5mm. These will be available to purchase through our online platform or at your local hobby store. Here are the ones we’ve found to work really well.

  • PETg (Commonly found in food-safe molds)
  • HIPS (Commonly found in disposable cups)
  • ABS (The stuff Lego is made from)
  • Polystyrene (Commonly found in product packaging)
  • Polyethylene (Commonly found in sheet and foamed sheet)
  • Acrylic PMMA (Commonly found in light-up signs)
  • Polycarbonate (Commonly found in drinks bottles)


Concrete has recently been a bit of a trend in homewares, and there’s a good reason for it. Being such a versatile material, it can be used for almost anything: from egg cups to bookends, to lampshades. If you're looking to create an undeniably smooth surface and you haven’t worked with concrete before, we suggest you give it a go! A beautiful material that adds texture to any product. Readily available from any local (or large) hobby store. Creates a brutalist aesthetic. Beautifully smooth surface and rich texture. Easy to work with, leaving to cure overnight.


Everything that can be made, can be made with chocolate. Chocolate lamps, chocolate soap, chocolate faces. Chocolate is a great material to work with, providing you don’t get too hungry and end up eating your beautiful creations… Great for presents! Available from your nearest shop. Cheap to buy. The Mayku FormBox molds work with all kinds of chocolate. Easily customisable with any extra flavors and decorations you have to hand.

And it doesn’t stop there!
