3D Printing Processes
Our online 3D printing service enables you to 3D print your custom part on demand. We offer six 3D printing technologies to transform your 3D files into plastic, metal, and elastomeric parts. With more than 120 3D printers, we have unmatched capacity that reliably delivers parts within days. In addition to a broad material selection, we offer several post-processing options to improve cosmetics or enhance mechanical properties.
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.
Multi Jet Fusion (MJF)
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.
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.
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.
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 built.
Advanced Photopolymers
When your project requires advanced mechanical properties beyond stereolithography (SLA) and PolyJet, explore our advanced photopolymer materials unlocked by Axtra3D Hybrid PhotoSynthesis (HPS) technology.
FDM 3D Printing Through Protolabs Network
FDM (fused deposition modeling) 3D printing builds parts by heating and extruding thermoplastics layer-by-layer. FDM is a good 3D printing options for strong prototypes and functional parts.

Get in-depth design advice to optimize 3D-printed parts. Designing with additive manufacturing in mind can accelerate production time and reduce overall cost.
Check Out The ToolkitSurface 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. |
Custom 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. |

3D Printing FAQs
How much does 3D printing cost?
expand_less expand_more3D printing cost per part is dependent on a multitude of factors, including design, material, process, and post print operations. Typically, the post print operations account for most of the part cost, especially if manual labor is involved. In general, the laser powder bed sintering processes like SLS and MJF are the most optimal economic choices for end use parts if cost is a key factor. Check out this blog post to better understand what drives the cost of 3D printing.
How do I choose a 3D printing technology?
expand_less expand_moreWhen selecting a 3D printing technology, first determine critical design requirements like strength, temperature resistance, water resistance, aesthetics, or durability. This will often help you determine if a metal or plastic 3D printing is needed for your application. Check out this 3D printing material selection guide for further assistance on technology options to align with your design requirements.
What type of file format is needed for 3D printing?
expand_less expand_moreThough all file types are ultimately converted to STL (.stl) before printing, the recommended file type to upload is STEP (.stp/.step). SOLIDWORKS (.sldprt), and IGES (.igs/.iges) files. Check out further guidance on how to design .stil files for 3D printing. Learn more about .stl files for 3D printing.
How large of a part can you 3D print?
