Carbonara CF tube

Carbonara is a high-endurance, high-quality carbon fiber X beam for Voron and Monolith 3D printers, utilizing the stock build sizes of 250, 300, and 350.

Key features:
  • High torsion resistance 
  • Made with high-temperature resin. 110°C short-term temperature resistance, good for 90°C chamber.
  • Ultra light, up to 58% weight reduction from a standard 2020 aluminium extrusion (before hardware and inserts).
  • Smooth 3K carbon strand finish
  • Pre-drilled, easy installation
  • Unmatched price/performance

Tested for 800 hours at VERY high speeds, 500-1300mm/s @ 50.000-100.000m/s² with 80ºc chamber.

IMPORTANT!

  • The printed inserts are a MUST  to ensure maximum performance. 
  • Make sure they are all aligned and facing the same direction.
  • The inserts must be a snug fit, not loose.
  • Hollow spacers aren't mandatory, they are only used to facilitate installation.
  • Inserts must be printed in CF/GF filament with HDT ≥ 110°C, such as, annealed PET-CF, PCPBTGF, etc.

                         The indented part of the printed inserts is meant to face the linear rail.
