Proto Processes 3DP-PolyJet Resin

Material Description

PolyJet Resin is a versatile and advanced 3D printing material known for its exceptional material properties. This resin is a photopolymer-based thermoset material, typically composed of acrylic or epoxy-based polymers. It exhibits excellent mechanical properties, including a high tensile strength of up to 60 MPa, which makes it suitable for various engineering and prototyping applications. Its flexural modulus ranges from 1,400 to 2,300 MPa, indicating robust stiffness. Additionally, PolyJet Resin offers impressive heat resistance, with a glass transition temperature (Tg) of around 60-70°C, allowing it to withstand moderately elevated temperatures. Moreover, its excellent impact resistance and elongation at break, which can reach up to 15%, make it suitable for parts that may experience dynamic loading. This resin is also characterized by its fine printing resolution, making it ideal for intricate and detailed 3D prints. Overall, PolyJet Resin is a high-performance material choice in additive manufacturing, balancing strength, detail, and thermal properties for a wide range of applications.

Common Industry Applications

PolyJet resin finds applications in medical devices, consumer products, and aerospace for its multi-material and fine-detail 3D printing capabilities.

Design Recommendation

PolyJet 3D printing offers high-quality surface finishes but requires careful consideration of support structures and model orientation. Design your model to minimize the need for extensive supports and ensure proper drainage for the support material, as PolyJet uses a gel-like support material that should be removed post-printing. Keep in mind that thin walls and fine details are achievable with PolyJet, but their successful printing depends on proper orientation and curing methods during post-processing, which may include UV curing and cleaning.

Cost Saving Tip

Cost-effective PolyJet resin 3D printing relies on design choices that minimize the need for support structures. Thin walls and draft angles should be integrated into the design to reduce support requirements and, in turn, material consumption. Reusing unused support material, as well as performing regular machine maintenance, helps extend the life of consumables like print heads and material cartridges, ultimately reducing operational expenses.
