R&D Technologies through our vendor Stratasys can now offer metal 3D printing.
ADDITIVE METALS (DMLS)
Additive Metals processes fuse powdered metal and alloy materials layer-upon-layer to "grow" complex objects from sliced 3D CAD data (.STL files). The key advantage of the additive metals processes is their ability to rapidly and cost-effectively produce highly complex metal prototypes and end-use parts. Direct Metal Laser Sintering (DMLS) is the premier technology for "growing" (a.k.a. 3D Printing, Additive Manufacturing) high quality metal and alloy parts and tooling using a high-wattage laser in an ambient temperature build chamber. Parts are anchored to the build platform by support structures, and these supports are removed during post-processing. DMLS produces parts with fine detail, tight tolerance and excellent physical properties.
The quality of DMLS-built objects is a significant step forward from the earlier generation SLS LaserForm indirect metal process. Stratasys is also able to utilize their in-house high speed 5-axis milling and post-processing systems to secondarily post-machine and post-process 3D objects for improved surface finish, tighter tolerance, and/or enhanced functionality.
