Plastics
Acrylic
Acrylic is generally considered safe for laser cutting. Cast acrylic is generally a nicer material to work with compared to extruded, but it has poorer dimensional/thickness tolerance.
Wherever possible we purchase recycled acrylic. Please place any unusable offcuts into the acrylic recycling bin.
Engraving Laminate
This material is made from two layers - one thin coloured layer bonded to a thicker layer of a different colour. By carefully engraving away the top surface you can make very hard wearing signs and labels.
PETG, Polycarbonate
PETG and Polycarbonate are generally safe to cut with a laser cutter, but aren't great to work with. Polycarbonate in particular discolours around the edges and cut edges can melt back together again.
We don't typically keep these materials in stock.
Wood
Laser-safe MDF
Normal MDF may contain glues which release harmful combustion byproducts. All the MDF the Maker Space purchases is "laser grade" and made with glues compatible with laser cutting.
Laser-safe Plywood
Normal plywood may contain glues which release harmful combustion byproducts. All the plywood the Maker Space purchases is "laser grade" and made with glues compatible with laser cutting.
