Boston Micro Fabrication (BMF) is introducing four materials for its microArch series 3D printers. These advanced materials, including 3D Systems’ Figure 4 HI TEMP 300-AMB, BASF Ultracur3D 3280 and BMF resins HTF and SR, enhance BMF’s ability to address needs of industries like aerospace, medical devices, electronics, and biotechnology.

New materials now available include:

Made for extreme thermal environments, this production-grade, ultra-high temperature resistant plastic offers a Heat Deflection Temperature (HDT) of over 300°C. With rigidity and visualization properties, Figure 4 HI TEMP 300-AMB is made for HVAC components, motor enclosures, and low-pressure molding.

Applications: HVAC systems, consumer appliances, motor enclosures, and low-pressure molding.

Key Benefits: HDT over 300°C, no secondary thermal post-cure required, and rigidity.

A ceramic-filled resin that has stiffness (Young’s modulus of 10 GPa) and a high heat Deflection Temperature (>280°C), Ultracur3D 3280 is ideal for tooling, molding, and wind tunnel testing. Its low viscosity and stable suspension make it easy to handle and print.

Applications: Tooling, wind tunnel testing, and mold inserts.

Key Benefits: Stiffness and temperature performance, high stability, and easy to print.

Designed by BMF, HTF is a high-temperature resistant, tough, and biocompatible resin. It is autoclave-sterilizable. With an HDT of 152°C and compatibility with aerospace and biotech applications, HTF offers versatility.

Applications: Aerospace, precision electronics, and biotechnology.

Key Benefits: Biocompatibility, autoclave sterilizable.

A soluble, sacrificial material, SR enables the creation of single-use molds for parts produced with other materials that cannot be easily printed, such as polypropylene (PP) or polyoxymethylene (POM).

Applications: Single-use molds, low-volume part production, and PDMS applications.

Key Benefits: Dissolves in a sodium hydroxide solution.
