Nylon vs Polycarbonate: When PLA and PETG Stop Cutting It

When desktop FDM hobbyists outgrow PLA and PETG, nylon and polycarbonate are the next step for heat-resistant, load-bearing functional parts, but only with proper drying and hardware.

In this episode you'll learn:

• PA6 reaches around 70 MPa tensile strength while PA12 sits at 45 to 55 MPa, with PA12 absorbing only about 1.5% moisture by weight versus up to 9% for PA6.
• Polycarbonate delivers 55 to 75 MPa tensile strength and notched impact toughness of 600 to 850 J/m, an order of magnitude above most FDM materials.
• Pure polycarbonate has a glass transition around 145°C, and Prusament PC Blend is rated for use up to 113°C per the Prusament data sheet.
• Prusament PC Blend prints at a nozzle temperature of around 275°C, and Polymaker requires an actively heated chamber for PC-FR, PC-ABS, and PC-PBT variants.
• Nylon and PC are both highly hygroscopic; without drying, prints show cracking, milky surfaces, and degraded mechanical properties within hours of room exposure.
