Our extensive fleet of over 120 industrial 3D printers ensures fast turnaround, reliably delivering your parts in a matter of days. To meet diverse application needs, we offer six distinct 3D printing technologies and a variety of post-processing options to enhance aesthetics and improve mechanical performance.
Metal 3D Printing
DMLS (Direct Metal Laser Sintering) employs a fiber laser to draw on atomized metal powder, fusing it into fully dense metal components.
Prototyping in production-grade materials
Complex geometries
Functional, end-use parts
Reducing metal components in an assembly
Stereolithography (SLA)
SLA uses an ultraviolet laser to trace liquid thermoset resin, building parts layer by layer until completion.
parts requiring high accuracy and features as small as 0.002 in.
good surface quality for cosmetic prototypes
form and fit testing
Selective Laser Sintering (SLS)
SLS uses a CO₂ laser to fuse nylon-based powder layer by layer, forming thermoplastic parts.
jigs and fixtures
housings
snap fits and living hinges
Multi Jet Fusion (MJF)
Multi Jet Fusion selectively applies fusing/detailing agents on nylon powder beds, heated layer-by-layer to form solid functional parts.
parts requiring consistent isotropic mechanical properties
functional prototypes and end-use parts
complex and organic geometries with fine features
Pressure Die Casting
PolyJet sprays liquid photopolymer droplets via multi-jet nozzles, curing layer by layer into elastomeric parts.
prototyping designs for overmolding or silicone rubber parts
combining two colors or durometers into a single part
simulating elastomers or flexible parts
Advanced Photopolymers

Surface Finish Options for 3D Prints
| Unfinished | Dots, or standing "nibs," remain evident on the bottom of the part from the support structure remnants. | |||
| Natural | Supported surfaces are sanded down to eliminate the support nibs. | |||
| Standard | Supported surfaces are sanded, and the entire part is finely blasted for a consistent look. Note that the layers are still present. | |||
| Custom | Soft-touch paint, clear part finishing, painting, masking, color matching, decals/graphic, and texture finishes are available. | |||
Finishing
Looking to boost the strength, clarity, or appearance of your 3D-printed parts? Choose from microfluidic and micro-resolution materials, metal plating, secondary machining, and custom finishes like painting, clear coating, and decaling.
| Clear Coat | Clear cosmetic finish that can be applied to ABS-Like Translucent/Clear (WaterShed XC 11122) and PC-Like Translucent/Clear (Accura 60) materials. | |||
| Painting | After smoothing the part with sanding and polishing, parts can be painted with automotive-grade paint. Provide a pantone color with your quote request. We also offer soft-touch painting. | |||
| Plating | Electroless nickel plating can be used to achieve parts that are similar to cast aluminum or magnesium. | |||
| Dyeing | Dyeing is another method for adding color to 3D prints. This is faster option with a limited color selection, so is a more cost-effective choice than painting. | |||
| Decaling | Decaling can be used to add a logo or other graphics to boost cosmetics or function. | |||
| Polishing | We can polish parts to a mirror-like finish. If this is a requirement, we ask that you provide either a drawing or image that indicates your finish expectations. | |||
| Heat Treatment | Harden and strengthen metal 3D prints with multiple heat treatment options: NADCAP heat treatment, hot isostatic pressing (HIP), solution annealing, and aging. | |||
| Machining | Machine metal 3D prints to achieve exceptional surface finish quality or meet tight tolerances. | |||

Layer-by-layer part fabrication unlocks previously unachievable design possibilities, outperforming traditional processes like molding, machining and casting.
Cost-efficient complex organic geometries
Integrate multi-component designs into one part
No upfront tooling expenses
24-hour fast part manufacturing
Internal structures for advanced heat/flow
