DESC – Dehydrating Evacuated Storage Cabinet (Currently in Beta, expected release date for customer units is July 2014)


What does a DESC do?

DESC is a long term filament storage and dehydrating system that provides the optimal conditions to maintain repeatable material operation between prints.

Why do I need a DESC?

Humidity is the archnemisis of plastic filaments. Most plastics used in 3D printing are hydroscopic, meaning they have a tendency to absorb water over time. This can lead to decreasing print performance over time as a particular spool collects moisture from the air. Defects such as holes and bubbles may begin to appear on the surface of prints. As the issue persists, the structural integrity of parts may begin to suffer and may even lead to hot end jams and potential printer damage.

Why is a DESC better than other storage solutions?

Our DESC unit actively dehydrates its contents by evacuating the chamber and allowing the moisture to evaporate at low temperatures. Other airtight storage containers may be successful at keeping humidity out, but they do nothing to remove the moisture that has already built up on the filament. The common solution to removing existing moisture is to lightly heat treat the plastic in an oven, but this is time consuming and can easily lead to deformed filament.

DESC was designed from the ground up to increase operator productivity by making it extremely easy to use. DESC doubles as a printer docking platform and includes vibration dampening feet to reduce the required recalibration frequency. Since the printer is intended to sit directly on top of the DESC unit, changing materials is simple. The contents can be viewed externally through a double paned glass window for easy material selection. Since individual spools do not require special packaging they can be quickly fed into the extruder once selected. Chamber depressurization is automatically switched on after the door is closed to reduce the potential for operator error.
