Explanation of Properties
Strong material used for functional prototypes and visual models. In combination with soluble support material, it can be used to create accurate models of medical scans such as skulls and brains. Resistant to degredation from radiation, withstands heat up to 98C
Strong, rectaliner mechanical prototypes - human/animal models - complex structures that require soluble support
PLA (Polylactic Acid). More ecofriendly, better aesthetic and fuctional details and less likey to warp than ABS. Heat resistance up to 60C. Not suitable for heavy load and high temperature. Suitable for display purpose. The support is easily dissolvable in water.
Fine detail for display models. Can be used with water soluble support to create complex geometries
A strong, durable, flexible material. TPU95 has a shore-A hardness of 95, and an elogation of up to 580% at break. It is highly chemically resistent, and stands up to wear over time. Adhesion between layers is much stronger than most other 3d printing filaments, resulting in end use parts that exhibit more uniform strength charageteristics in all dimensions.
Good for flexible pieces that can bend or stretch without breaking. Can also be used in dual material printing to simulate overmolded parts, or create living hinges. Available to print with soluble support as well.
CPE (copolyester) materials are chemical resistant, tough and demonstrate good dimensional stability. Heat resistance up to 82C short term or 70C long term. Tougher than PLA while maintaining the same detail level.
Finer detail and better durability. Good for functional prototypes and mechanical parts.
Class I biocompatible resin. Rated for use in mouth for up to 24 continuous hours. Can be steam autoclaved. Extrodinarily difficult to print with, not reccomended for use cases that do not have a need for the part to be inside the body.
Used primarily for surgical guides for dental surgery. Parts should be at least 3mm thick
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.
Investment casting only. Not meant for producing parts to be used on their own
