Pyrex® (Borosilicate) Filamet™ is available as 1.75mm and 2.85mm filament and as pellets.

Specs: This filament comes in 0.5kg and 1kg spools and 1kg bags of pellets. It contains 69.0% - 71.0% glass and has a density of 1.5g/cc. Parts produced with this product will not sinter optically clear.

High Compatibility: This Filamet™ enables any open-architecture Fused Filament Fabrication 3D printer to produce glass objects. Even works in 3D printing pens!

Easy to Print: All you need is an open architecture 3D printer, a 0.8mm hardened steel nozzle, and a model to print. Print like regular PLA. Place your spool so that the filament coming off is going straight into the extruder. The flow rate in your slicer may need to be adjusted up to 135%. Little to no warping occurs during printing.

Advanced Properties: Filamet™ is less hygroscopic than regular PLA. Filament dryers have adverse effects on Filamet™. Spools should not be dried.

Fully Sinterable Glass Filament: Once fired in a sintering furnace, the result is 100% glass. Sintered parts are opaque and not optically clear. Instructions for sintering this product.

Special Qualities: Resistance to thermal shock.

Used For: Partner Innovators have used this filament for jigging apparatus for shape memory alloy development.

Eliminate tooling and machining costs for short run manufacturing, prototyping, and one-off glass part needs.
