The Industrial PP-like resin from Harz Labs is an advanced engineering material specifically designed for high-impact strength and precision in 3D printing applications. This resin boasts mechanical properties that closely mimic injection-molded polypropylene, allowing for the creation of resilient and durable prototypes and functional models such as housings, latches, and similar components.

Key features of this resin include low shrinkage (less than 0.5 %) and excellent dimensional accuracy, ensuring that printed models retain the exact size as designed in digital form and remain unchanged after post-curing. The resin is highly stable, with no sedimentation or gel formation occurring in the vat, eliminating the need for mixing. Additionally, it is odorless, causes no irritation, and contains no volatile monomers, making it safe for use with natural ventilation even in small workshops.

In terms of mechanical properties, the resin offers a balance between rigidity (more rigid than the Industrial Nylon-Like resin) and flexibility (more flexible than the Industrial ABS resin). It exhibits high hardness and tensile strength, with an elongation at break of approximately 40%, a tensile strength of around 35 MPa, and a tensile modulus of about 500 MPa. It also features a Shore hardness of approximately 73 D. This combination of properties makes the Industrial PP-like resin an excellent choice for engineering projects that require both strength and flexibility.
