About Us


We are the leading provider of additive manufacturing solutions. From application discovery and launch to production-grade manufacturing capabilities, we can help you deliver new product and supply chain innovations uniquely enabled by the latest additive technologies.


Additive manufacturing has been an important prototyping tool for decades. But recent innovations in hardware technologies have opened up an entirely new set of applications for additive. You can now engineer and manufacture production-grade end-use parts that have material properties that mimic those of traditional manufacturing techniques such as injection molding or CNC machining.

Fast Radius offers a wide range of services to help companies capture these new opportunities uniquely enabled by additive. We can help you discover new applications, quantify the technical case and business case to support these applications, and ultimately launch the program with a best-in-class additive manufacturing production system.

We also recognize that traditional manufacturing techniques will continue to play a crucial role in part production, so we also offer injection molding, CNC machining, cast urethane and other manufacturing techniques through a set of highly qualified strategic partners.

We look forward to working with you at all stages of your product development and manufacturing lifecycle. Please contact us to learn more.

Our Services


  • Fast Radius is a leading production partner for Carbon’s Digital Light Synthesis (DLS) technology. We have one of the largest fleets of machines currently deployed, including production-grade tools such as the Smart Part Washer and a bulk resin dispensing system. We have access to all the Carbon DLS materials, including developmental materials not publicly available.

    Materials include:
    • RPU 70: ABS-like material, performs well under stress, combining strength, stiffness and toughness.
    • FPU 50: Similar to polypropylene, FRU has high impact strength and cycle life. It is designed to withstand repetitive stresses, making it ideal for tough enclosures, hinging mechanisms and friction fits.
    • EPU 40: Similar to urethane rubber, EPU exhibits excellent elastic behavior under cyclic tensile and compressive loads. EPU is useful for demanding applications where high elasticity, impact and tear resistance are needed such as cushioning, gaskets and seals.
    • CE 221: Similar to a 14% glass-filled Nylon 6, CE 221 is a high-performance material with excellent strength, stiffness and thermal stability that makes it a good choice for use at elevated temperatures. It has the highest heat deflection temperature of the Carbon materials at 231º C.
    • EPX 81: Similar to glass-filled PBT, EPX 81 has a heat deflection temperature of 140°C and excellent abrasion resistance, making it useful in a variety of automotive, industrial, and consumer product settings.
    • SIL 30: Similar to TPE, SIL 30 is the first additive material to offer a unique combination of biocompatibility, low durometer and tear-resistance.

  • As one of the first production partners of HP’s Multi-Jet Fusion (MJF) technology, we deliver quick-turn prototypes all the way up to repeatable, production-grade manufacturing for end-use parts. We are continually driving innovations in post-processing for HP MJF parts, including unique coloring options, chrome plating and premium surface finishes.

    We currently offer HP’s PA 12 material, a versatile thermoplastic for high-density parts. PA 12 has excellent chemical resistance and is ideal for complex assemblies, housings, enclosures and watertight applications.

    We have a robust roadmap of materials for the HP MJF technology. Please contact us to learn more about additional materials currently in development.

  • Additive Manufactured Thermoplastic and Elastomeric Parts

    Finally, a true alternative to low volume injection molding in terms of quality and cost. Fast Radius leverages in-house additive manufacturing equipment and expertise to produce your parts to the same quality standards you would expect from injection molding. We are not a service bureau, we are a manufacturing company and we know what it takes to make end use parts.

    Advantages of Additive Manufacturing
    • Produces geometries that cannot be machined
    • No tooling investment
    • Injection molded quality without the cost or lead-time of tooling
    • Parts delivered in days
    • Enables rapid product iteration
    • Allows low volume niche products to become viable

  • ADDITIVE MANUFACTURED (3D PRINTED) METAL PARTS

    When you have the right application for metal additive manufacturing the value is incredible. Additive manufacturing is unique in that complexity is free, unlike traditional manufacturing. For instance, you can “drill” a curved hole with additive manufacturing that is impossible to make with subtractive manufacturing.

    The downside of metal additive manufacturing is that it is costly and there is no economy of scale like in traditional manufacturing. The general rule of thumb is that is a part can be machined, it should be machined.

    Presently, the most successful applications for metal additive manufacturing are in the aerospace industry where optimizing the strength to weight ratio with high temperature materials is extremely valuable and has an immediate positive return on investment.

    Advantages of Additive Manufactured Metal Parts
    • Complexity is free
    • Allows for geometries not possible previously
    • Ability to achieve very high strength to weight ratio
    • Works with high temperature materials
    • Faster lead times than machining for complex parts

  • Fast Radius provides rapid quotes and short lead times on CNC machined parts. We are comfortable with tight tolerances, complex geometries and exotic materials, but of course we will be happy to machine your “easy” parts as well. Our focus is low to medium volume part production for applications where the part has to be right and the promised delivery date has to be met.

    Advantages of CNC Machining
    • Lower cost than additive manufacturing
    • High dimensional accuracy
    • Wide range of materials
    • Very consistent parts
    • Parts can be produced as fast as same day

  • Similar to injection molding, urethane casting produces hard plastic parts using a two-part mold. When the two halves of the mold are combined, a void is created that the urethane is poured into until it cures. Unlike injection molding however, urethane casting uses soft mold materials, such as silicon rubber, and is more suited to small runs or one-off parts. The mold must still be manufactured by CNC Machining, Additive Manufacturing, or another process. When the mold can be made easily or exists already and the run is small, Urethane casting is ideal.

    Benefits
    • Low cost for small runs
    • Consistent mechanical properties
    • Wide variety of materials
    • Short lead-times
    • Good solution for 25 parts or less

  • Injection molding is a proven process for producing plastic parts with high accuracy and fine feature detail at medium to high volume. Injection molding requires that a mold (tool) be built specifically for the part to be produced. Molds typically have a 6 to 8 week lead-time depending on size and complextiy. The mold will require a significant capital investment, but each part coming off the mold will be relatively inexpensive. The pro of injection molding is that you can make a lot of parts fast and inexpensively. The con of injection molding is that you are locked into a design and any change to you part geometry can incur significant cost to modify of build a new mold.

    Advantages of Injection Molded Parts
    • High dimensional accuracy
    • Fine feature detail
    • Low part cost
    • Facilitates mass production
    • Wide variety of materials
