Markforged 50cc High Temp Fiberglass CFF Spool (HSHT)

Markforged 50cc High Temp Fiberglass CFF Spool (HSHT)

Markforged High Strength High Temperature (HSHT) Fiberglass is defined by two key characteristics: near-aluminum strength and exceptional performance at elevated temperatures. The second strongest fiber in the Markforged portfolio, HSHT is the go-to material for parts that must remain strong and reliable under heat — where standard fiberglass or carbon fiber would fall short.

Key Features

• Near-Aluminum Strength — 5× stronger and 7× stiffer than Onyx; strength close to 6061-T6 Aluminum
• High Temperature Resistance — Retains strength at temperatures up to 105°C ambient (heat resistant to 140°C)
• Second Strongest Markforged Fiber — Only Carbon Fiber exceeds it in the Markforged lineup
• Continuous Fiber Fabrication (CFF) — Precisely laid into Onyx for maximum reinforcement
• Distinctive Light Yellow Color — Easy identification in composite parts
• Compatible Printers — Mark Two, X7, FX20
• 50cc Spool — Ideal for targeted high-temp reinforcement zones
