Our exclusive study »Post-Processing of Metal Fused Deposition Modeling Parts« reveals the significant challenge of poor surface quality and low component resolution in metal FDM, often caused by the staircase effect. By focusing on the green stage of production—where parts possessed reduced mechanical properties—the study investigates chemical and mechanical finishing techniques that would be impossible on fully sintered metal components

Key-Topics of this Study:

• Surface Quality Enhancement through chemical vapor smoothing, as well as shot peening and blasting on green bodies, effectively reducing surface roughness before sintering
• Shorter lead times were achieved in the green stage, significantly reducing post-processing time and costs
• Leveraging the plastic-like properties of green bodies could lead to more cost-effective and faster production, especially for low-complexity components produced in small quantities
