Several New Engineering and Dental 3D Printing Materials Recommended

Key Takeaways

• ANTINSKY’s new lineup targets niche performance needs: high‑temperature stability, chemical resistance, flexibility, and rapid print cycles.
• PPA‑CF30HT and PPS‑CF are carbon‑fiber reinforced engineering filaments with flexural moduli above 12 GPa and heat‑deflection temperatures (HDT) exceeding 170 °C.
• TPU85A and TPU95A‑HS deliver Shore‑A hardness of 85 and 95 respectively, with elongation at break > 500 %.
• Dental resins are formulated for splints, denture bases, and diagnostic models, meeting ISO‑10993 biocompatibility standards.
• All materials are calibrated for Bambu Lab H2/D series printers but can be adapted to other FDM or SLA platforms with appropriate nozzle and bed settings.

Introduction

In additive manufacturing, the printer defines how a part is built, while the filament or resin dictates what can be produced. ANTINSKY has expanded its portfolio with purpose‑built polymers and photopolymers that move beyond generic, “one‑size‑fits‑all” options. The new offerings split into two groups: high‑performance engineering filaments and flexible dental‑grade resins.

Engineering Filaments

PPA‑CF30HT – Ultra‑Rigid Carbon Fiber Composite

• Base polymer: Polyphthalamide (PPA)
• Reinforcement: 30 % short carbon fiber
• Flexural modulus: 12 136 MPa (≈12 GPa) – among the stiffest FDM materials on the market
• Density: 1.26 g · cm⁻³
• Mechanical strength: XY tensile 122 MPa; flexural 208 MPa
• Thermal performance: HDT 176 °C; melting point 280 °C
• Print window: 270–300 °C nozzle, 80–90 °C heated bed, 120–150 mm · s⁻¹ feed rate, 0.4 mm nozzle (wear‑resistant metal recommended)

PPA‑CF30HT shines in applications where metal machining is cost‑prohibitive and design iteration is frequent—e.g., automotive sensor brackets, aerospace brackets, and high‑load fixtures. Its high stiffness allows functional prototypes to bear real‑world loads, reducing reliance on downstream CNC machining.

PPS‑CF – High‑Temperature Polyphenylene Sulfide Composite

• Base polymer: PPS (Polyphenylene sulfide)
• Reinforcement: 20 % carbon fiber (continuous‑strand)
• Flexural modulus: 9 800 MPa
• Density: 1.34 g · cm⁻³
• Mechanical strength: Tensile 115 MPa; flexural 190 MPa
• Thermal performance: HDT 190 °C; melting point 285 °C
• Print window: 260–285 °C nozzle, 85 °C bed, 100–130 mm · s⁻¹

PPS‑CF is tailored for chemical‑resistant components such as pump housings, valve seats, and oil‑field tooling where exposure to aggressive solvents is expected.

Flexible Filaments

Both TPU grades are formulated for impact‑absorbing parts, wear strips, and ergonomic grips. TPU95A‑HS adds a proprietary hardener that raises tensile strength while maintaining a high Shore‑A rating, ideal for medical device housings that must resist repeated flexing.

Dental‑Grade Photopolymers

ANTINSKY’s dental portfolio includes three certified resins:

All three meet ISO‑10993‑5 cytotoxicity and ISO‑10993‑10 irritation criteria, enabling in‑office fabrication of patient‑specific appliances with minimal post‑processing.
