Our Most Popular 3D Printed Plastics

General Purpose

3D Printing Technology HP Multi Jet Fusion

Nylon PA-12

HP Multi Jet Fusion

The best printed plastic on the market for most applications. Durable, lightweight, inexpensive and quick to produce. Good chemical and heat resistance. Superior surface finish makes it an excellent option for industrial parts, functional prototypes and consumer products alike.

Highest Accuracy

ABS

Fused Deposition Modeling (FDM)

Tried-and-true plastic for accurate parts and functional prototypes. Good alternative to nylon PA-12 for slightly larger single-piece parts; however, we generally recommend nylon PA-12 when possible due to its lower cost, improved finish and faster print time.

Large Prints

PMMA

Large Format Printing

The largest 3D printing available, great for producing molds and tooling. A fast and inexpensive alternative to large machined parts, especially in small to medium runs. The Voxeljet VX1000 is also able to print sand casting molds and cores.

Specialized 3D Printed Plastics

High Heat

Ultem 9085 & Ultem 1010

FDM

Flame-retardant and FST-rated thermoplastics with very high heat resistance and strength-to-weight ratio. Commonly used in commercial transportation industries, especially aerospace.

Biocompatible

ABS M30i & PC-ISO

FDM

Quickly create custom medical-grade plastic parts, tooling and prototypes with no setup costs or additional fees. Can be EtO or gamma sterilized. Click here for full list of sterilizable materials.

Rubber

Rubber 3D Printing

Thermoplastic Polyurethane (TPU)

MJF

Rubber-like TPU for creating flexible parts and products. Commonly used for gaskets, seals and other rubber parts. Great for small to medium runs of industrial-strength prints.

ESD

Electrostatic Dissipative ABS

FDM

Durable and affordable protection against electrostatic discharge. ABS-like mechanical quality. Consistent surface resistance with very low particle contamination.

UV-Resistant

ASA

FDM

UV-resistant, ABS-like mechanical qualities. Commonly used to create outdoor parts and products that won’t fade or crack from sunlight.

Translucent

ABSi

FDM

Translucent plastic that is even stronger than traditional ABS. Smooth finish makes it a good choice for prototypes and models that resemble final products.

Selective Laser Sintering (SLS) Materials

Selective laser sintering (SLS) offers a relatively large print bed compared to most 3D printing technologies. The range of filled and unfilled nylons that are compatible with SLS allow printed parts to possess a variety of mechanical and aesthetic properties, from hard and rigid to soft and flexible. Though we recommend the HP Multi Jet Fusion for most applications, SLS can offer additional value for parts which exceed the size limits of other technologies or require specific mechanical properties.

Unfilled Nylon SLS 3D Printing

Unfilled Nylon 2201

Smooth surface finish with strong mechanical strength and thermal resistance. Good for functional prototypes and aesthetic models.

Glass Filled Nylon SLS 3D Printing

Glass-Filled Nylon

Excellent stiffness and thermal resistance, often used as an inexpensive alternative to ABS for large, rigid parts.

Flame Retardant Nylon SLS 3D Printing

Flame-Retardant Nylon

Plastic with a chemical flame retardant which protects structure against fire with a carbonating coating.

Aluminum Filled Nylon SLS 3D Printing

Aluminum-Filled Nylon

One of the most dense 3D printed plastics. Has a metallic appearance as well as excellent thermal and conductive properties.

Carbon Filled Nylon SLS 3D Printing

Carbon-Filled Nylon

High strength-to-weight ratio and excellent stiffness. Popular in transportation industries, including automotive and aerospace.

3D Printed Metals

3D printed metals allow you to produce metal parts, products, prototypes and tooling with no additional setup time or fees. Like all 3D printing, direct metal printing, metal printing and direct metal laser sintering (DMLS) can produce designs with complex internal geometries like nested cores or spiral vents. 3D printed metals offer good value for functional prototypes, conceptual models or small- to medium-sized production runs.

Direct Metal Printing Materials

Direct Metal 3D Printing

Stainless Steel 304L

The most versatile and widely used stainless steel. Easy and consistent fabrication with good corrosion resistance and strength. Many general-purpose commercial applications.

Metal 3D Printing

Stainless Steel 17-4

Very high strength, heat-treated stainless steel with good corrosion resistance. Often used for cooling and aerospace applications. Meets MPIF 35 standards.

3D Printing Metal Parts

Stainless Steel 316L

Easily machined metal with high temperature resistance. The most commonly used MIM powder. Many heat-sensitive applications in aerospace, automotive and medical industries. Meets MPIF 35 standards.

Bronze Parts 3D Printing

316 Stainless Steel/Bronze

The best option for post-printing machining. Able to achieve very tight tolerances. High wear resistance. Ideal for tooling, fixtures and medical parts.

Stainless Steel Custom Parts 3D Printing
