We have four (4) printers that use spools of 2.85/3.00 mm (diameter) filament. Below is a breakdown of the qualities, restraints and design tips for each material.
PLA is the best (and cheapest) option for medium to full-sized models. It's perfect for medium to high-quality prototypes with limited functionality, and can register small details down to 1mm. Models with 20% infill tend to be stiff and durable, while models with ≤ 40% can feel like solid objects. PLA us made from Tapioca and Corn starch, making it biodegradable and recyclable.
Take note that features below 1mm will not register accurately, or at all, and can cause issues with layer quality if there are too many small features. Serious overhangs or thin supporting geometry is almost guaranteed to be problematic, providing inadequate support for a model while printing. Printing with multiple colors or filaments can increase the potential of failure up to 4X and materials like dissolvable must be removed with Limonene, so parts will smell like citrus.
Used by many manufacturers worldwide, Nylon (polyamide) is well-known for its impressive durability, high strength-to-weight ratio, flexibility, low friction, and corrosion resistance. With its ability to withstand significant mechanical stress, Nylon is a great choice for 3D printing tools, functional prototypes, and end-use parts.
Highly versatile for industrial applications, TPU 95A (thermoplastic polyurethane) filament is the go-to choice for a wide array of manufacturing projects that demand the qualities of both rubber and plastic. Designed for 3D printing consistency, TPU 95A is a semi-flexible and chemical resistant filament with strong layer bonding. In addition, it is easier and faster to print than other TPU filaments.
Ultimaker PP (polypropylene) is durable. It has high toughness, exceptional fatigue resistance, and low friction. It also has good chemical, temperature, and electrical resistance. PP is one of the most widely used plastics on the planet. From electrical components to living hinges, PP is the go-to material for prototyping and end-use products.
With Ultimaker PC (polycarbonate) filament, you can print strong and tough parts that retain dimensional stability when subjected to temperatures as high as 110 ºC. Our PC is a perfect filament for printing molds, tools, functional prototypes and parts for short-run manufacturing.
CPE (copolyester) materials are chemical resistant, tough and demonstrate good dimensional stability. It is a preferred choice for both functional prototypes and mechanical parts. While both CPE and CPE+ provide similar performance characteristics, CPE+ provides the added benefit of higher temperature resistance and increased impact strength.
PVA (polyvinyl alcohol) is a water-soluble support material for multi-extrusion 3D printing. With a good thermal stability, Ultimaker PVA is ideal for printing complex models that require supports for large overhangs, deep internal cavities, and intricate geometries. Designed for a seamless 3D printing experience, our PVA provides good adhesion to PLA, Tough PLA, CPE, and Nylon.
Filament (Markforged Mark Two)
Our Mark Two prints exclusively with Onyx CFF Nylon 6, and can be reinforced with the following fibers.
Nylon mixed with chopped carbon fiber offers a high-strength thermoplastic with excellent heat resistance, surface finish, and chemical resistance. Onyx serves as a thermoplastic matrix for Markforged’s composite parts. It can be printed alone or reinforced with one of our continuous fibers to give strength comparable to aluminum. Use Onyx filament for anything from tooling and fixtures to end-use parts.
Carbon Fiber Reinforcement
Carbon fiber is a thin filament made up of carbon atoms organized into a crystalline structure. Because of its very high stiffness and strength, it is widely used in the aerospace and automotive industries. Carbon fiber material is strong enough to replace aluminum at half the weight; it has a flexural strength of 470 MPa (68 ksi) which is 20% higher than the yield strength of 6061 aluminum. Its tensile strength is 700 MPa (102 ksi), more than twice the ultimate tensile strength of aluminum. To learn more about carbon fiber material properties, check out the data sheet.
Fiberglass is composed of extremely thin strands of glass bundled together into a fiber. It is traditionally used in composites for boat, automobile, and aircraft manufacture. Use fiberglass composite material to print parts that are an order of magnitude stiffer than typical 3D printed objects at the most affordable price. Fiberglass has a flexural strength of 210 MPa (30.5 ksi) and a tensile strength of 590 MPa (85.5 ksi). For more information on 3D printed fiberglass material properties, check out the data sheet.
High-Strength, High-Temp Fiberglass Reinforcement
Fiberglass is composed of extremely thin strands of glass bundled together into a fiber. With superior heat resistance and a flexural strength that is second only to carbon fiber, HSHT fiberglass is ideal for applications requiring high heat and impact resistance or high elasticity.
Kevlar Fiber Reinforcement
Kevlar is a synthetic fiber developed and produced by DuPont. Know for its light weight and toughness, it is traditionally used in products such as tires, sails, rope, and protective equipment. Kevlar is an excellent material for 3D printing, and is best utilized in parts that will take a beating. Its low density and high durability make it a great option for applications involving a lot of motion or interfacing with production parts.

PVA is a water-soluable material, similar to Elmer's glue. It is an ideal support material for highly-detailed models with cavities or features that would otherwise be obstructed or ruined by non-soluable supports. Dual-extrusion jobs incur a $2 service fee, on top of the total price of materials consumed.
|TPU||150µ, 200µ||Black, White, Blue, Red|
TPU 95A filament is highly versatile for industrial applications, perfect for designs that demand the qualities of both rubber and plastic. Designed for 3D printing, TPU 95A is a semi-flexible and chemical resistant filament with strong layer bonding.
|PC (Polycarbonate)||150µ, 200µ||Black, White, Transparent|
Polycarbonate is a top material choice for engineers and manufacturers who require parts that need to retain their strength, toughness and shape while operating in high-temperature environments (110º C).
FabLab, CAD nor RIT are responsible for any injuries or damage that result from any objects printed, CNC'd or laser cut by FabLab staff.
Our Form 2 printers are capable of tolerances equal to injection-molded parts with most compatible resins. SLA, in general, is best suited for models requiring extraordinary details (i.e., anthropomorphic models for your design final). Formlab's standard resin is easily painted after some quick sanding with 220p or smaller sand paper. Tough, flexible, high temp are great for functional parts; Castable is designed for the lost-wax method and registers details down to 25µ, perfect for jewelry.
For demanding applications, Formlabs has carefully-engineered resins to capture the finest features in your model. You can confidently create accurate and robust parts, ideal for rapid prototyping and product development. Perfectly smooth right out of the printer, parts printed on the Form 2 have the polish and finish of a final product. Standard resins, while great for aesthetics, cure with brittle properties and can shatter when met with blunt forces.

Formlabs' fastest printing material, Draft Resin is suitable for printing large, bulky parts quickly. With a 300 micron layer height, it has acceptable accuracy for prototyping needs while enabling faster design iterations. Draft Resin is perfect for truly rapid prototyping and printing large parts or multiple part assemblies quickly.
Supports print resolutions: 300 microns. No post-curing required.
Tough Resin simulates the feel and many of the important mechanical properties of ABS plastic. Acrylonitrile Butadiene Styrene is a very common thermoplastic that provides a good balance of strength and flexibility. Tough Resin creates strong engineering prototypes and has been developed to withstand high stress and strain. Consider using this material for works-like prototypes and assemblies, including designs with snap fit joints and living hinges. For further finishing, Tough resin can also be machined once printed. Tough Resin can be printed at 50 and 100 micron layer heights on the Form 2. Toughness refers to a material’s ability to absorb energy before fracturing. When a tough material yields, it will undergo some deformation rather than just shattering. In other words, tough materials have a little more “give” than brittle ones.
Grey Pro Resin is an Engineering Resin designed for high precision, moderate elongation, and low creep. These mechanical properties make Grey Pro Resin a versatile material for a wide range of engineering applications, including concept modeling and functional prototyping. Highly resistant to deformation over time, Grey Pro Resin is especially suitable for printing parts intended for repeated use or handling.
Formlabs most impact resistant material, Durable Resin is also highly wear resistant, capable of extreme deformation before breaking, and has low friction compared to Standard and Tough Resin. Use Durable to prototype models that will eventually be made from polypropylene (PP) or high density polyethylene (HDPE). It is best used when these features are required in a room-temperature application.
Polypropylene is very commonly used in situations where high elongation, deformation, and/or impact resistance are required. Applications of polypropylene include items like toothbrushes, car bumpers, packaging, razors, and more.
Durable is ideal for engineering prototypes and has been developed to withstand high strain. Consider printing in Durable Resin for applications that require impact resistance for rugged prototyping and for models that feel or look like real polypropylene. Like Flexible Resin, Durable Resin also works for objects that require some flexibility. Unlike Flexible Resin, Durable is also useful when you need to maintain good rigidity.
Whether you’re optimizing your manufacturing process, rapidly iterating through designs, or assessing form, fit, and function, our Engineering Resins for the Form 2 are formulated to withstand extensive testing and perform under stress.
NOTE: The FabLab tolerance guide found both on Confluence and in the catalog does not apply to Elastic resin. Please review Formlabs' design guide for further information.
Flexible (Not Available)
Flexible Resin is an elastomer that allows for bendable/compressible parts to be printed on your Formlabs printer.
Flexible Resin is not stretchable as it has low elongation. Your model may break if it is exposed to stretching forces. Full material property specs can be found here.
Rigid Resin is an Engineering Resin designed for stiffness and precision. The material is reinforced with glass to offer a very high modulus and a polished finish. Rigid Resin is highly resistant to deformation over time. The glass-powder reinforcement enables Rigid Resin to be stiff relative to other Formlabs materials.
High Temp Resin is designed for functional prototyping in high heat applications. Understand the technical specifications and best uses. The most notable property of this material is its Heat Deflection Temperature, which is the temperature at which a material will deform under a specified load. For High Temp, the heat deflection temperature is 289 °C @ 0.45 MPa. High Temp is ideal for applications requiring the part to stand up to high temperatures with minimal loading. The material has almost no flex, however, so snap fits and living hinges are not suited for printing with High Temp Resin.
Use Formlabs Castable Resin to produce detailed fine jewelry through the investment casting process. Developed specifically with investment casting in mind, Castable burns out cleanly with no ash or residue.
Castable Resin is an acrylate photopolymer, which requires a different process from a traditional wax schedule. Instead of melting at low temperatures, Castable Resin transitions to a gas. The recommended burnout schedule is designed and tested to allow Castable Resin to transition into a gas gradually. The slow transition reduces the possibility of the investment cracking due to rapid expansion of the printed part. To fully enable the gas transition, maximize the airflow by adding venting, by active ventilation, or by blowing out molds when possible. Ideally, the thermal expansion of the investment should be well suited to the thermal expansion of your 3D printed material. To transition from primarily a wax-based casting process, adjust the process accordingly to achieve a successful cast.
Read further to understand the step-by-step workflow, recommendations, and special considerations for designing, printing, preparing investments, and burning out Castable Resin. The instructions for each phase in the process include troubleshooting tips. This information is provided in a similar downloadable publication, Formlabs Application Guide: Recommended Burnout Process and Casting Guide.
Use Formlabs Castable Wax Resin to produce highly detailed jewelry by casting parts through direct investment casting with minimal part finishing (no post-cure required). Castable Wax prints are strong enough to use for prototyping and fitting before production. A 20% wax-filled material, Castable Wax prints both delicate and bulky models with ease. Parts printed in Castable Wax are ready to cast after washing without post-curing for fast, clean burnout and a streamlined casting process. Understand the step-by-step workflow, recommendations, burnout schedules, and special considerations for designing models, printing, preparing investments, and casting successfully with Castable Wax Resin.

The very stuff used to ship any and everything around the world coincidently makes for a great rapid prototyping tool! Corrugated cardboard can be used as a substitute for a final material to check if a design's CAD matches the design intent, fitment or placement of features, or basic ergonomics and human factors. Beyond that, cardboard can't bear any weight or significant stresses without buckling, and is easily ruined by any moisture. If you're looking to just see how something looks or feels outside of a design schematic, corrugated cardboard is your best option.
This includes printer paper (80 lb copier paper), construction paper, some Canson and Bristol boards, as well as painter's tape. Anything with a gloss, semi-gloss, matte or any other type of coating (including plastics and inks) will not be cut.

Matboard is like upgraded cardboard, in terms of prototyping materials. The solid internal structure can be used for a wide rage of prototypical applications, though not ideal for anything bearing weight and/or dynamic forces. One great example would be flat-pack designs with interlocking slots that, once assembled, create a 3D object from flat shapes (think Ikea furniture).
