What They're Saying
“ProtoCAM's turnaround times are exceptional, and their prices compared to others are always better. There's a lot more value added in working with ProtoCAM.” — Matthew Bellenoit, B. Braun Medical
“There are many companies in the rapid prototyping business that are automated and there’s no personal interface. That's the big difference between ProtoCAM and other companies.” — Jim Eldon, Design Associates
“When we need to make a change, ProtoCAM always accomplishes it accurately. We see the results we planned on consistently. They do a very good job providing quality products.” — Rory Kiphart, Biomet
“ProtoCAM's best attribute is their attention to detail and customer service. Their willigness and desire to keep in touch with me is impressive, and physical walkthroughs ensure me quality standards are being met.” — Todd Frick, Clair Brothers Audio Systems
“I’ve worked with a lot of different rapid prototype houses and I've consistently ended up back at ProtoCAM. Quality is key and they deliver consistently. They’ve given us a significant advantage over our competitors.” — Dan Dunham, XOS
Also known as metal 3D printing, the direct metal laser sintering (“DMLS”) process involves the fusing of powdered metals with an infrared laser beam. This allows for the creation of metal prototypes and production pieces with no special tooling, and rapid turnaround times.
Our DMLS Work
Direct metal laser sintering (DMLS) is an ideal rapid prototyping solution for clients that need high-quality 3D metal parts or metal prototypes quickly.
No special tooling is required, allowing for DMLS turnaround times of one week or less. Our advanced direct metal laser sintering (DMLS) equipment allows for the creation of short-run products and prototypes in extremely complex shapes and forms.
In direct metal laser sintering (DMLS), 3D metal parts are created by fusing (“sintering”) powdered metals with the heat from an infrared laser beam. These metal layers are repeatedly laser sintered, creating the desired three-dimensional piece based on a 3D CAD model or .stl file. DMLS is an additive manufacturing sequence process, as parts gradually increase in size until they reach prescribed dimensions.
Advantages of DMLS metal 3D printing:
- DMLS metal 3D printing uses homogenous materials, minimizing potential complications.
- Parts produced using DMLS metal 3D printing can easily be machined, EDM processed, polished, etched, textured and more.
- Parts can be produced using a variety of material types.
Limitations of DMLS metal 3D printing:
- DMLS metal 3D printing typically costs much more than other rapid metal prototyping techniques.
- Depending on part geometry, DMLS metal 3D printing presents size limitations.
