Dry Ice Blasting as an Efficient Post-Processing Method in 3D Printing

Additive manufacturing enables the production of complex components with reduced material usage. However, post-processing, particularly the removal of support structures, remains a key challenge. Conventional methods are often time-consuming and carry the risk of material damage. For this reason, toolcraft AG relies on an automated dry ice blasting process that makes the procedure more efficient and material-friendly.

Traditional methods for removing support structures often involve mechanical processing using tools such as chisels or milling machines. These methods require significant manual effort and can damage delicate components. In dry ice blasting, fine particles of frozen carbon dioxide are blasted onto the workpiece at high pressure. The extreme cold makes the support structures brittle, causing them to detach from the component without leaving any residue. Since the CO₂ transitions directly into its gaseous state upon contact with ambient air, no additional cleaning is required, which accelerates the overall process.

In addition to saving time, automation also enhances workplace safety. The reduction of manual interventions minimizes the risk of injuries and material defects. Especially in industries with high precision requirements, such as aerospace and medical technology, this method provides a reliable alternative. Furthermore, the reduced material stress helps decrease waste, leading to cost savings and lower environmental impact.

“Companies that continue to rely on traditional, manual processes will face increasing pressure in the future. The market is increasingly demanding automated and technology-driven solutions,” says Christoph Hauck, Chief Technology and Sales Officer at toolcraft AG.
