Carbon Fiber HTPLA - Dark Grey - 2.85mm
SKU: 8A2 PRPHTPLA2DGY
For exceptional accuracy, finish & performance, choose Carbon Fiber
Proto-pasta Carbon Fiber Composite HTPLA is a combination of milled carbon fibers & high-performance PLA. Resulting 3D printed prototypes & end-use parts are characterized by exceptionally form stability up to 160 deg C (320 deg F) when heat treated.
- Base material: Heat treatable PLA with higher temperature resistance
- Characteristics: low odor, non-toxic, renewable-sourced biodegradable polymer
- Molecular structure: Amorphous "as printed", partially crystalline when "heat treated"
- Additives: 10% by weight high-purity, milled carbon fiber
- Max particle size: 0.15 mm (may limit nozzle size & layer thickness)
- Density & length: 1.3 g/cc for 360 m/kg (1.75) & 136 m/kg (2.85) lengths
- Min bend diameter: 40 mm (1.75) & 100 mm (2.85)
- Glass transition (amorphous "as printed" material use limit): approx. 55 deg C
- Melt point (crystalline "heat treated" material use limit): approx. 170 deg C
- Note that melting resets heat treated material to amorphous "as printed" state
- Max use temp: 50 deg C "as printed", 160 deg C when "heat treated"
- Application-specific use limits are geometry, load & condition dependent
- Typical heat treating conditions: 110 deg C (225 deg F) for 30 min
- A large range of temperatures & times can yield acceptable results
- Typical dimension change when heat treating: 0.6% x/y shrink, 1% z growth
- Scale for slicer when heat treating: 1.006 or 100.6% x/y, 0.99 or 99% z
- Hold filament end when unwrapping spool to avoid looping
- Do not bend tighter than min bend diameter
- When done printing, secure filament end to avoid looping
- Store in cool, dry place away from UV light for peak performance
More about HTPLA & heat treating:
HTPLA is a semi-crystalline grade of PLA optimized for heat treating (also known as annealing or crystallizing) for higher temperature use. Without heat treating, "as printed" amorphous PLA loses significant stiffness (and the thus the ability to retain form) as the material approaches it's relatively low glass transition temperature. Heat treating creates a more crystalline molecular structure for maintaining stiffness to near melting, thus extending the useful range of HTPLA, but also creates shrinkage. HTPLA parts should be scaled in slicer to compensate for shrinkage when heat treating.
STORAGE: One large resealable bag with slider + an extra desiccant pack are included with every spool. The bag and extra desiccant are a great way to safely store your filament spool when not in use. It keeps your filament bone dry & free from any dust or dirt particles, so it's always ready for your next print.
