3D Printing / Additive Manufacturing Capabilities
3D printing, also known as additive manufacturing, builds three-dimensional objects by depositing material layer by layer based on digital 3D model data. Unlike subtractive manufacturing (machining) which removes material, additive manufacturing adds material only where needed, reducing waste and enabling geometries impossible with traditional methods. Technologies include Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), Direct Metal Laser Sintering (DMLS), and Multi Jet Fusion (MJF). 3D printing has evolved from purely a prototyping tool to a production manufacturing process for aerospace, medical, dental, automotive, and consumer products.
±0.005"-±0.010" (±0.13-0.25mm) typical; varies by technology
1-5 business days for prototypes; 1-4 weeks for production
$5-$500+ per part for prototypes; $10-$1,000+ for metal parts

3D Printing / Additive Manufacturing in Seattle — FAQ
How many 3D Printing / Additive Manufacturing providers are in Seattle, WA?
The Seattle-Tacoma-Bellevue metropolitan area has approximately 2,600 manufacturing establishments, many of which offer 3d printing / additive manufacturing services. The area employs about 78,000 manufacturing workers, ensuring a skilled workforce for your project.
When should I use 3D printing vs. CNC machining?
Use 3D printing for complex internal geometries, rapid prototyping (1-5 parts), lightweight lattice structures, and parts that would require significant machining setup. Use CNC machining for tight tolerances, better surface finish, stronger material properties, and medium-to-high volumes.
What is the strongest 3D printing material?
For plastics, PEEK and carbon-fiber-filled nylon offer the highest strength. For metals, titanium Ti-6Al-4V and Inconel 718 printed via DMLS/SLM achieve properties comparable to wrought material after heat treatment. Metal 3D printing is used for flight-critical aerospace components.
How accurate is 3D printing?
Accuracy varies by technology. SLA achieves ±0.002"-±0.005". SLS achieves ±0.005"-±0.010". FDM achieves ±0.010"-±0.020". Metal DMLS achieves ±0.003"-±0.005". For precision applications, post-machining of critical features is common.
Can 3D printed parts be used in production?
Yes, 3D printing is increasingly used for end-use production parts. Aerospace uses metal 3D printing for fuel nozzles and brackets. Medical uses it for custom implants. Dental uses it for aligners and crowns. Automotive uses it for jigs, fixtures, and low-volume components.
