Dry Desiccant While Printing

----------------------------------------------------- AD -----------------------------------------------------

Are you also huge fans of the Gridfinity system, but struggle to create the perfect layout for your drawers, boxes, or storage spaces?

That is exactly the problem GRUND.DEV (aka Makerworld: Xc1Camtain) and I wanted to solve… and we developed (drumroll please 🥁🥁🥁)

DRY INSIDE SAVE OUTSIDE

This model provides a functional solution for utilizing waste heat inside the P2S enclosure to regenerate desiccant during normal printing operations. The design is based on the principle that thermal energy already present in the build chamber can be reused to reduce additional energy consumption for drying processes.

The system consists of four components: 

• a mounting interface for the printer air intake
•  a desiccant container
•  a removable lid
•  and a safety retention strap. 

The mounting interface replaces the original air inlet cover and allows integration without permanent modification. A dedicated cavity is included to store the original cover, ensuring full reversibility of the modification.

The desiccant container is positioned in the airflow and thermal zone near the heated bed. This enables gradual drying of moisture-loaded desiccant during printing. Even partial regeneration reduces the required energy for subsequent oven drying.

The safety strap is designed to prevent accidental detachment of the container during high-speed printing, protecting both the print and the printer hardware.

Due to the thermal environment, the use of high-temperature resistant materials is required. The geometry is optimized for repeatable installation and removal without damage.

Printing Profile:
The model was printed using ASA due to its high thermal resistance and dimensional stability at elevated temperatures (up to 100 °C printing bed). To compensate for material shrinkage, a global scaling factor of 101% was applied.  The mounting interface may optionally be printed in PETG if thermal exposure is lower.
