Printed Fused Silica & Optical Glass

Glass resisted additive manufacturing longer than almost any material. Now printed fused silica delivers transparent lattices, freeform optics, and microfluidic channels that no mold could ever release.

Microfluidic Devices

Sealed internal channels in transparent glass — chemically inert, autoclavable, and impossible to injection-mold.

Architectural Cast Glass
Architecture

Architectural Cast Glass

Textured facade and partition panels cast from printed molds, giving every panel its own light signature.

Custom Labware

Print the Green Body
Step 01

Print the Green Body

Silica nanoparticles suspended in a photopolymer are cured layer by layer, producing a soft, opaque 'green' part that holds the final geometry.

Debind & Sinter
Step 02

Debind & Sinter

The polymer binder is burned out and the part is sintered near 1,300°C, where it shrinks uniformly and fuses into solid, fully dense silica.

Polish to Optical Grade
Step 03

Polish to Optical Grade

Surfaces are ground and polished until roughness drops below a nanometre — the step that separates a translucent blank from a working lens.

Not all glass prints the same way. Silica dominates optics, borosilicate rules the lab bench, and soda-lime remains the workhorse of architecture. Each brings its own shrinkage, sintering window, and finishing burden.
