3D Printing Materials

Choosing the right material for a given project is every bit as important as choosing the right 3D printer. In fact, the 3D printer to be used is often determined by material requirements.

Whether a product needs to be rigid, flexible, mechanically strong, medical grade, food grade, chemical resistant, heat resistant, flame retardant, colorful or clear will all determine which material is the best fit.

Below is a list of some of the most popular plastics and metals for 3D printing. Check out our 3D printed materials page for even more information on materials.

Plastic Materials

Nylon 12 (PA)—The go-to choice for industrial-strength parts. Used by MJF and SLS. High heat and chemical resistance, low water absorption. Quality gray (MJF) or white (SLS) matte finish that can be dyed black.

Nylon 11 (PA)—Another SLS and MJF nylon with more flexibility than nylon 12. Frequently used for tubing, fuel lines and hoses as well as living hinges. Available in white (SLS) or gray (MJF) with black dye options.

ABS—Engineering plastic for FDM. Very accurate but has a poor machine finish and is slower to produce than PA-12. Available in a limited range of colors, plus translucent (ABSi) and medical-grade (ABS M30i) options.

Ultem 9085 and Ultem 1010—Flame-retardant, high-performance thermoplastics with very high heat resistance and strength-to-weight ratio. Often used in aerospace applications.

PMMA—Dyeable plastic used for large format printing. Good tensile strength and high heat resistance. Large surfaces can warp.

Filled Nylons—Filled nylons offer many options for strength, rigidity, aesthetics and chemical and heat resistance. Glass-filled nylon is available for both MJF and SLS, while other filled nylons are exclusive to SLS.

Thermoplastic Elastomer (TPE)—Flexible thermoplastic elastomers for creating rubber-like parts with SLS.

Polycarbonate (PC)—A durable, biocompatible polycarbonate used by FDM for medical applications. Highly sterilizable. Comes in white.

ASAUV-resistant FDM material, great for outdoor applications with lots of sun exposure.

Polypropylene (PP)—Semi-rigid, extremely flexible thermoplastic polymer with high heat and corrosion resistance. Often used in the food industry and for piping. Available for FDM and soon to be available for MJF.

Thermoplastic Polyurethane (TPU)—Elastic, rubber-like plastic with high resistance to oil and grease. Used in a wide range of consumer and industrial applications. Currently only available for FDM, but slated to be introduced for MJF in the next year.

PPSF/PPSU—FDM plastic with very high heath and chemical resistance. Used for testing performance industrial prototypes and small runs of parts.

Metal Materials

Stainless Steel—The workhorse of 3D printed metals. High strength and corrosion resistance, sterilizable and easy to machine. Very economical in small to medium quantities when using direct metal printing. Varietie include 304, 316, 17-4 and more.

 

Tungsten-Bronze—High-density shielding material with a high melting point for direct metal printing. Used for radiation shielding and in applications for aerospace, medical and nuclear industries.

Titanium Ti64—Strong, corrosion-resistant and biocompatible metal for DMLS. Commonly used for medical devices and applications in the transportation industry.

Cobalt Chrome MP1—Another biocompatible DMLS metal with even greater corrosion resistance and strength, often used for replacement joints and dental implants.

Aluminum ALSi10Mg—Lightweight and strong DMLS metal, used for parts with thin walls or complex geometry.

Inconel 625 and Inconel 718—DMLS nickel alloys with superior mechanical strength as well as corrosion and thermal resistance. Often used in high-heat, high-corrosion performance applications, especially in aerospace.

Maraging Steel—Hard and durable tool steel, used to produce molds, tooling, and other industrial fixtures with DMLS.

Finishing Options

PolyJet Printing Company

Dyed Plastic Finish

Standard dyes include include black, red, blue, green, purple and orange, with custom dyes available on request. Opaque dyes are available for PolyJet and FDM. PolyJet also supports translucent dyes. Multi Jet Fusion and SLS both have opaque black options.

Sanding and Blasting Finish

Sanding, Blasting, Tumbling and Clear Coating

These standard finishes are available on almost all RapidMade products. They provide smoother textures and higher quality, consumer-grade feel. We are also able to simulate wood texture on ColorJet parts.

Painted 3D Printed Parts

Custom Painted Finish

We can create clear topcoats as well as single- and multi-color custom paint finishes on almost all RapidMade products. Paints are available in matte, satin and gloss.

Thermoformed Custom Coatings

Custom Coatings

Available on most of our products, custom coatings like Teflon, Cerakote and polyurethane improve abrasion resistance, enhance appearance and reduce friction.

polished+surface+metal+3d+printed+face

Metal Polishing

Polishing improves resistance to abrasion and makes parts easier to clean and sterilize. It also amplifies the appearance of secondary finishes like anodizing, silk screen, plating and powder coating.

Plastic and Metal Plating

Great for surface conductivity and electromagnetic interference applications, plating adds strength and rigidity to plastic parts while providing an elegant, metal-like appearance. It further improves the appearance of metal products.

Powder+coated+investment+cast+parts

Powder Coating

Powder coating is an inexpensive, permanent finish which protects metals from scratches, rust and corrosion while hiding imperfections. It has a smaller environmental impact than other coating processes.

Full+assembly+of+machined+components+anodized

Anodizing

Anodizing prevents corrosion on aluminum components, creates a harder surface that is more resistant to wear and comes in many color options.

laser+engraved+anodized+machined+parts

Laser Engraving

Less expensive than CNC engraving, laser engraving is simple to create. It can be done directly from a PDF and allows for custom branding or engraving part and serial numbers.
