BigRep introduces storage cabinet for 3D printer filaments

Designed to protect filament from material degradation, BigRep’s new Shield dry cabinet stores up to 60 kg of filament in an environment that’s more than 99% humidity-free. The company claims the cabinet reduces material waste on FFF-style printers by 20% and can save up to 50% on nozzle- and extruder-repair costs.

Without proper storage in a humidity-controlled environment, 3D printing filaments—particularly engineering-grade materials such as PA 6/66, TPU, PVA, and PET—absorb airborne moisture. This increases printing errors, nozzle clogging, and machine downtime. The cabinet reportedly maintains a 0.1% humidity level by looping air through a controlled desiccant chamber without the use of heat; long-term exposure to heat can cause filaments to dry out.

The cabinet’s interior is 480 mm wide by 480 mm deep by 1,200 mm high and accommodates 12 4.5-kg spools.

BigRep collaborated on the Shield’s development with Amboss+Langbein, a company with nearly 40 years’ experience building drying systems for plastics.
