From functional prototypes to full production runs — 3D Creation Systems delivers industrial-grade 3D printing in FDM, SLS, and SLA with expert engineering support from our Minneapolis and Denver facilities. Domestic manufacturing. Proven results.
Each technology has unique strengths. We help you choose the right process for your application, material requirements, and budget — so you get the best result every time.
FDM (Fused Deposition Modeling) is the most widely used 3D printing technology — building parts layer by layer from thermoplastic filament. It's ideal for functional testing, durable prototypes, and end-use production parts where strength and temperature resistance matter.
Functional prototypes, end-use production parts, large components, aerospace, automotive, and industrial tooling.
SLS (Selective Laser Sintering) uses a high-powered laser to fuse nylon powder layer by layer — without the need for support structures. This makes it the ideal choice for complex geometries, intricate internal channels, and production parts where surface quality and mechanical performance are critical.
Complex assemblies, medical devices, end-use production parts, durable functional prototypes, and multi-part mechanisms.
SLA (Stereolithography) uses a UV laser to cure liquid resin into solid parts with exceptional surface finish and fine detail resolution. It's the preferred technology for visual prototypes, dental and medical applications, and any part where surface appearance and dimensional precision are the top priorities.
Visual prototypes, dental models, medical devices, investment casting patterns, and parts requiring fine text or intricate features.
