Formlabs Engineering Resins

Formlabs Engineering Resins

Innovative materials for demanding applications

Take your designs to the next level with engineering resins from Formlabs. Browse the comprehensive range of resins, with properties including elasticity, rigidity, durability, toughness and temperature resistance. Perfect for creating complex models and tools, with features such as hinges and snap-on parts.

Developed for use in the most demanding projects, Engineering Resins are suited to both iterative design cycles and the production of final use parts with ambitious physical characteristics. Facilitating living hinges, snap-on parts and resistance to extreme temperatures, Engineering Resins bring functionality to your models while guaranteeing stability and durability throughout the design and testing phases of any project. Provided in easy-fit one-litre cartridges, Formlabs makes swapping between resins a quick, clean and fuss-free process.

Elastic 50A Resin

This incredible resin is useful for people that currently prototype using silicone. This 50A Shore durometer material can bend and stretch repeatedly without breaking. For medical models, consumer prototypes and props for special effects, it’s unbeatable.

Flexible 80A Resin

Flexible 80A Resin is the most stiff soft-touch material in Formlabs’ library of Flexible and Elastic Resins, with an 80A Shore durometer to simulate the flexibility of rubber or TPU. Balancing softness with strength, Flexible 80A Resin can withstand bending, flexing, and compression, even through repeated cycles. Flexible 80A product sheet.

Grey Pro Resin

Build with confidence using one of the most durable resins currently available. With exceptional stability and rigidity, this versatile material is the perfect choice for end-use parts that need to be built to last. Also suitable for building functional prototypes, Grey Pro Resin lets you work with the confidence that your development models will accurately represent each finished part.

Rigid 4000 Resin

Formlabs’ Rigid 4000 Resin is bonded with glass for exceptional strength and a naturally smooth, polished finish. Durable and resistant to deformation in use, Rigid 4000 Resin is ideal for building fine detail and thin, self-supporting layers, as well as being your go-to material for jigs and fixtures.

Rigid 10000 Resin

This highly glass-filled resin is the stiffest material in the Formlabs engineering portfolio. Choose Rigid 10K Resin for precise industrial parts that need to withstand significant load without bending. Rigid 10K Resin exhibits a smooth matte finish and is highly resistant to heat and chemicals.

Tough Resin

Strong yet flexible, Tough Resin is a versatile and durable material, which is perfect for the production of soft-touch surfaces and snap-fit components. Ideal for iterative prototyping of hard-wearing parts for short-term use as part of the design cycle, Tough Resin demonstrates exceptional strength, withstanding knocks and jolts – and quickly recovering its original form – as your product undergoes developmental testing.

Tough 1500 Resin

This resin is the most durable option. Choose this if you are planning to create stiff parts that can bend and spring back with ease. It’s great for simulating the strength of polypropylene, as well as for creating jigs and fixtures that require repeated deflection. Any prototypes you need to print that bend and spring back into shape are perfect for this material too.

Durable Resin

As one of the most versatile materials available, turn to Durable Resin when you need to accurately simulate the finish of parts that, in final production, will be built using polypropylene or high-density polyethylene. Highly resistant to impact and elongation, Durable Resin is the perfect fit for development projects that require a combination of living hinges, snap fits and a smooth finish.

Flexible Resin

Add cushioning, dampening and a soft-touch finish with Flexible Resin. Developed with ergonomics in mind, this rubber-like material withstands repeated compression to deliver parts that yield to pressure, yet spring back to their original shape. With similar characteristics to trainer soles and tyres, Flexible Resin is the perfect choice for producing wearables, toys and overmoulds.

High Temp Resin

No other material withstands extremes as well as High Temp Resin. It is the ultimate choice for bespoke ducting for liquid or gas, for prototyping moulds, or for housing components that need to withstand heat when in use. Incorporate this hard-wearing material in a development cycle and the production of final use parts for results suited to long term use, which retain their original shape and support broad solvent compatibility.

Draft Resin

If you want to be able to go through several design iterations in a single day, Draft Resin is for you. Use it to print three to four times faster than other Formlabs materials. If you are using the entire build volume of the machine, a part can be produced with 300-micron layers in six hours, compared to 20 hours with Standard Resin. Once you are happy with your model, simply switch to a production resin to produce the final part.

Draft V2 Resin

Draft Resin prints up to four times faster than Formlabs standard materials, making it ideal for initial prototypes and rapid iterations to help bring products to market faster. Parts printed with Draft Resin exhibit a smooth grey finish and high accuracy. Use 200 micron settings for fast print speeds, or use 100 micron settings for models with finer details.
