Air technology for post-processing of 3D-printed components
Post-treatment is the third step on the way to a perfect 3D-printed component. Whether it's depowdering, surface finishing or heat treatment – reliable air technology is essential for process stability, cleanliness, and component integrity.
With industrial fans and side channel blowers from Elektror, plant engineers are offered efficient solutions for precise air flow, clean working environments and stable process conditions –engineered to meet the specific requirements of 3D metal printing.
Depowdering: Cleanliness through targeted air flow
Following the printing process, metal components and printing chambers must be thoroughly cleaned of powder residue without allowing hazardous metal dust to escape into the environment. Our fans and side channel compressors ensure controlled extraction – both in automated systems and in hand-held extraction solutions.
Your advantages:
- Targeted extraction minimises powder residues and health risks
- Reduction of dust exposure for employees and equipment
- Lower explosion risk thanks to controlled air flow
- Robust design for abrasive environments with fine metal particles
Surface finishing: Air technology for the perfect finish
Blasting, grinding, polishing or removing support structures generates dust, heat and blasting residue. Our compact, powerful radial fans ensure reliable dust extraction and controlled process cooling – even in space-critical systems.
Your advantages:
- Constant process air flow for consistent results
- Complete removal of grinding dust, residual powder and blasting material
- Improved surface quality thanks to stable process conditions
Post-heat treatment: Process reliability thanks to controlled air circulation
Whether it's debinding, stress relief annealing or tempering – heat treatment has a decisive influence on the mechanical properties of 3D-printed components. With Elektror’s heat-resistant industrial fans, plant engineers can ensure uniform temperature distribution and a controlled atmosphere in furnaces and heat treatment systems.
Our fans and extraction solutions:
- Distribute hot inert gas evenly in the furnace chamber
- Reliably extract process gases generated during debinding
- Enable controlled cooling of components after heat treatment by blowing in cool air
