Low-Volume Rapid Injection Molding with 3D Printed Molds

Accelerate product development, reduce costs and lead times, and bring better products to market by incorporating 3D printing and short-run injection molding into your development process.

An Efficient and Affordable Means for Bridge Tooling

Use 3D printed injection molds with both benchtop and industrial machines to effiecently and affordably produce hundreds to thousands of
functional prototypes, parts for pilot production, or end-use parts.

For Both Desktop and Industrial Molding Machines

Injection molds fabricated with Formlabs 3D printers have been tested with both desktop and industrial injection molding machines using a wide range of pressures, temperatures, and materials.

  • A Complete Desktop Ecosystem

    A Complete Desktop Ecosystem

    With a Formlabs 3D printer and desktop molding machine, its easy to get started 3D print injection molds in-house. Quickly test, validate, and itterate prototypes, produce pre-production parts in
    your final production material, and even manufacture end-use parts in limited series with limited equipment and training.

  • Production on the Factory Floor

    Production on the Factory Floor

    Grow your business and take on more small volume jobs by leveraging 3D printing to produce injection molds. Whether you outsource low volume tooling or machine inhouse, 3D printing can
    be used on the factory floor to affordable and efficiently fabricate injection molds while allocating skilled resources elsewhere.

Integrate into Any Injection Molding Workflow

Formlabs complete, easy-to-use ecosystem can seamlessly be integrated into any injection molding workflow. Save time and money on low-volume injection molding projects by leveraging the benefits of 3D printing to quickly and affordably produce hundreds to thousands of parts in traditional thermoplastics.

Tools to Get Started 3D Printing Injection Molds

Formlabs ecosystem of accesible 3D printers and high performance materials can be used to fabricate strong, smooth, highly detailed injection molds capable of producing hundreds to thousands of parts under demanding molding conditions.

  • Form 3+

  • Rigid 10K Resin 1 L

  • High Temp Resin 1 L

  • Grey Pro Resin 1 L

High Performance SLA 3D Printer

The Form 3+ produces molds with high-quality surface finish and fine features, ensuring that the injected parts come out true to design with minimal post processing.

Use the Form 3+ at various points of the product development process for a faster ROI. From 3D printing prototype parts to producing molds for short run production of those same parts, the Formlabs ecosystem is easy to integrate into any product development process.

Rigid, Strong, Industrial-Grade Molds

Choose Rigid 10K Resin for strong, stiff, and thermally resistant molds. The advanced strength ensures a mold made from Rigid 10K Resin can withstand the clamping and injection pressures without breaking, while the high stiffness enables the mold to maintain its shape under these pressures and produce accurate parts.

This highly glass-filled resin is the stiffest material in our engineering portfolio and can withstand significant load without deforming.

Temperature Resistant Molds

Consider High Temp Resin when clamping and injection pressures are not too high and Rigid 10K Resin cannot meet the required injection temperatures.

High Temp Resin offers a heat deflection temperature (HDT) of 238 °C @ 0.45 MPa, the highest among Formlabs resins.

General Purpose, Less Demanding Molds

Choose Grey Pro Resin when pressures and temperatures are low and dimensional accuracy of your molded part is less critical. Molds made from Grey Pro Resin will bend before breaking, potentially increasing longevity, but worsening accuracy over time as the mold is used.

Grey Pro Resin offers moderate strength, stiffness, elongation, and impact resistance, making it a suitable material for less demanding designs.
