Yes, we can 3D print fully dense metal parts in aluminum and stainless steel using Direct Metal Laser Sintering (DMLS). These parts have a fit and finish similar to cast parts. An example of a stainless steel part printed using DMLS can be seen in the image below:
Binder jetting is also another option for cost-effective metal 3D printing. It is often used to produce metal parts at a fraction of the cost of other metal processes with virtually no design limitations. Binder jetting machines have large build areas and produce parts at high speed, making it an excellent option for low to medium batch, rapid turn parts. The speed and affordability of binder jetting make it perfect for industries needing high-strength parts, such as industrial, automotive, consumer products, oil, and gas. An example of a stainless steel binder jet printed part can be seen below:
When deciding between these metal printing processes, it is crucial to consider the process limitations and tolerance capabilities. You can compare and review the tolerances of each process on our manufacturing standards page.
