Updated 3D Printer Design Reduces Cost, Downtime, Waste
IMTS 2018: SLM Solutions’ SLM 280 3D printer prints dense metal parts with quality surface finish, dimensional accuracy and strength.
SLM Solutions’ SLM 280 3D printer prints dense metal parts with quality surface finish, dimensional accuracy and strength. An updated enclosure encases the machine, filters and closed-loop powder sieving station. Its 280 × 280 × 365-mm build platform, bi-directional powder re-coating and open system architecture combine with an updated filter module to reduce costs, increase runtime and lessen process waste. The process waste can be disposed of as a dry mixture while the filter can be re-used continuously. According to the company, the printer builds upon the shielding gas flow of the previous model to achieve homogeneous mechanical properties and keep the process chamber clean.
An engineering modification that would have been impractical or cost-prohibitive in the past is realized on a machine tool performing metal 3D printing and machining in the same cycle.
Is additive manufacturing (AM) ready for production scale? The latest issue of Additive Manufacturing magazine highlights manufacturers who are succeeding with 3D printing for production right now.
The widespread outsourcing of large machine castings led a collaborative team at Oak Ridge National Laboratory to tackle the machine tool supply chain. The first step? 3D print the largest cast component.
