Looking for more than a desktop 3D printer can provide? Need an alternative to your in-house capabilities? Our industrial 3D printing service ensures accuracy and repeatability so you get highly precise parts—every time. At Protolabs, additive manufacturing is designed for functional prototypes, complex designs, and production components in as fast as 1 day.


3D Printing Processes

Metal 3D Printing

Direct metal laser sintering (DMLS) uses a fiber laser system that draws onto a surface of atomized metal powder, welding the powder into fully dense metal parts.

Carbon DLS

Carbon DLS uses digital light projection, oxygen permeable optics, and programmable liquid resins to produce plastic parts with excellent mechanical properties and surface finish.

LEARN MORE

Stereolithography (SLA)

Stereolithography (SLA) uses an ultraviolet laser that draws on the surface of liquid thermoset resin to create thousands of thin layers until final parts are formed.

LEARN MORE

PolyJet

PolyJet uses a jetting process where small droplets of liquid photopolymer are sprayed from multiple jets onto a build platform and cured in layers that form elastomeric parts.

LEARN MORE

Selective Laser Sintering (SLS)

Selective laser sintering (SLS) uses a CO2 laser that fuses nylon-based powder, layer by layer until final thermoplastic parts are created.

Multi Jet Fusion (MJF)

multi jet fusion 3d printed part

Multi Jet Fusion selectively applies fusing and detailing agents across a bed of nylon powder, which are fused in thousands of layers by heating elements into a solid functional component.
