Proto-Pasta specialty filaments unlock unique capabilities for electronics, robotics, and artistic applications. Metal-filled, conductive, and high-performance blends.
Carbon-black filled PLA that conducts electricity. Create touch sensors, capacitive buttons, circuit traces, and EMI shielding directly in your 3D prints.
Real iron powder infused PLA that can be magnetized, rusted for patina effects, and polished to a metallic finish. Heavy and realistic metal appearance.
Stainless steel powder filled PLA for weighted, metallic parts. Excellent for decorative hardware, jewelry, tool handles, and weighted mechanisms.
Short carbon fiber strands in HTPLA base for increased stiffness and reduced weight. Perfect for drone frames, structural brackets, and lightweight robot parts.
Prints like PLA but can be heat-treated (annealed) to achieve heat deflection temperatures up to 121°C. Bridge between PLA ease and ABS performance.
Natural fiber reinforced HTPLA with a beautiful matte texture that hides layer lines. Ideal for visible enclosures, product housings, and professional prototypes.
Polycarbonate-ABS blend for maximum impact resistance and heat performance. Used in automotive, industrial housings, and high-stress mechanical applications.
Genuine copper particles in a PLA matrix. Polish to reveal stunning copper sheen. Develops patina over time for authentic aged copper aesthetic.
Bronze powder infused PLA for artistic sculptures, awards, decorative hardware. Heavier than standard PLA with authentic metallic finish when polished.
Real coffee-infused HTPLA that smells like fresh coffee while printing. Unique brown color with organic texture. Fun for decorative and novelty prints.
Iron-filled HTPLA specifically formulated for controlled oxidation. Apply vinegar or salt water to create authentic rust patina effects on printed parts.
