See How Popular Polymer Technologies Stack Up
Two of our most popular 3D printing services, stereolithography (SLA) and selective laser sintering (SLS) offer engineering-grade options for parts. Learn how the two differ and how to pick the right process for your part.
Stereolithography (SLA) and fused deposition modeling (FDM) are two common plastic 3D printing process typically used for rapid prototyping. While both emerged in the 1980s, they use distinctly different ways to make parts, and as a result, have distinct advantages depending on your part requirements.
These two powder bed processes are similar, but there are some differences between the technologies that should be understood before making your manufacturing selection.
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. |
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. |

What is 3D Printing?
3D printing is a term used to describe a number of additive manufacturing technologies that produce parts one layer at a time from a 3D digital model. Some 3D printing machines will extrude a filament to create a parts, while others use lasers to sinter or cure raw materials like metal or plastic powders and liquid resins. There are a variety of 3D printing technologies that differ in terms of materials, surface finish quality, cost, and quantity to name a few.
Advantages of 3D Printing
Building parts layer-by-layer brings about many benefits that open up design possibilities that were previously unachievable through traditional processes like injection molding, machining, or casting.
- Complex, organic geometries with limited impact on part cost
- Consolidation of multi-component assembly into a single part
- No upfront tooling costs
- Fast production for parts within 24 hours
- Internal features for advanced heat transfer and flow applications
Common 3D Printing Applications
Additive manufacturing can be leveraged for both rapid prototyping and production in aerospace , medical, automotive, and other large industry sectors. Examples of typical parts, include:
- Form and fit prototypes
- Housings and enclosures
- Medical devices
- Snap fits
- Jigs and fixtures
- Heat exchangers and heat sinks
- Engine components
- Fuel injectors
- Surgical instrumentation
