Adsorber for Closed System

Drying of the incoming air into the powder tank

For an excellent result of 3D printed products, the powder must be dry and free of foreign particles. GIEBEL Adsorbers® help to dry and filter the incoming air. This produces the best printing results.

Metal 3D printing machines

The use of aluminum in 3D printing is particularly suitable for components that must be resistant to heat and stress, such as functional prototypes, mechanical components for the automotive sector or aerospace.

The aluminum alloy, which is available in powder form, is melted locally by a laser beam and thus built up layer by layer to form the structure to be produced. It is melted at the point of processing, creating a surface free of pores and cracks. Aluminum components produced by 3D printing manufacturing have better mechanical properties than those produced by the conventional casting process. This is due to the high cooling rates during the printing process.

Necessity of air drying

If the filament or powder binds water in the 3D printer, blowholes will form in the product. These blowholes reduce the quality and lead to high reject rates. For small packages, bagged silica gel can be used to dry them. It is easier to mount a respiration dryer on the powder container and to dry the sucked-in air directly at the inlet. This ensures that the raw material remains dry.

Breathing dryer in use

The effective solution is the use of a VV-R series adsorber. This is screwed onto the container and dries the air completely before contact with the powder.

Ambient dryer for container

An ambient dryer of the ES series is used to dry closed systems. This product can be regenerated after saturation in the oven or filled with fresh silica gel.
