The embedded carbon provides a beautiful dark matte gray finish with a slight sheen, resulting in 3D prints with exceptional accuracy, finish, and performance!

 

 

 

 

 

For exceptional accuracy, finish & performance, choose Carbon Fiber

Proto-pasta Carbon Fiber Composite HTPLA  is a combination of milled carbon fibers and high-performance PLA. Resulting 3D printed prototypes and end-use parts are characterized by exceptionally stability of form and potential use up to 155 deg C (310 deg F) when heat treated.

Adaptable to most PLA-compatible printers. Heated bed recommended for process ease, quality, and reliability, but not required. Printer should allow 3rd party filament, parameter adjustment, and nozzle replacement. Specialized machine adaptation and maintenance may be required for Proto-pasta materials particularly in continued use of abrasive materials. More on getting started. More about our release of Carbon Fiber HTPLA.

Printer

Some machines may require specific considerations for filament placement, path, adjustments, settings, or other preparation & maintenance.

  • Spool should unwind with minimal resistance
  • Mount filament above machine or other unobstructed position
  • Filament path must not bend tighter than min bend diameter
  • Filament should remain clean, dry & dust-free
  • Check weight before printing to avoid material run out
  • Be careful not to place printer too cool or warm environment
  • Clean print surface with alcohol or water
  • Apply & reapply appropriate adhesion aid as required
  • Carefully control first layer gap for adhesion without jamming
  • Limit build rate to balance melting, cooling & movement limits
  • Adjust layer fan to balance part & nozzle cooling
  • Isolate/insulate heater block from layer fan for consistent heating
  • Maintain & replace nozzle & other components when worn

Abrasive materials like Carbon Fiber and Metal Composites may cause premature wear of in line components such as bowden tubes, drive gears, nozzles, and other items in the filament travel path. Serviceable hardware including replaceable nozzles suggested. Wear resistant nozzles are recommended for extended use. Nozzles wear most quickly with flattening of the tip which affects nozzle diameter & distance to build plate. Inconsistent extrusion, inaccuracy & process instability. Extrusion width & first layer distance adjustments and/or replacement of nozzle. For more on nozzle replacement consider this blog demonstrating nozzle replacement & adjustments on a Prusa MK3. Reduce nozzle wear by minimizing over-extrusion & infill.

Printing

Product label suggest temperatures as a guideline based on typical nozzle set points. Appropriate settings can vary widely & in given good conditions, a wide range of temperatures can yield positive results. With relatively low print rates on hardware without hangups, HTPLA prints well at the low side of the recommended range. With high print rates on machines with hardware hangups, higher than labeled temperatures may be required for consistent extrusion. In some cases, oiling filament makes the difference between success & failure.

HTPLA Process Label

One specific problematic example is the Prusa MK3 which, by design, has a Prusa-specific heat break with an internal ledge that material can get caught on. To reduce need for nuance & risk of jamming, users should either replace the Prusa-specific heat break with a standard e3d v6 one, oil filament to help it slip past the Prusa-specific ledge, or print at an unusually high temperature. The trade off with high temperature as a solution is you should also match that with a high volume flow rate. Sounds great, right? It's okay except for the loss of detail when having to slow down for small part, fine feature, or high resolution printing.

Prusa MK3-specific, Carbon Fiber HTPLA process recommendations:

  • 1st layer temp to overcome jamming on Prusa MK3: 255 deg C
  • Min temp to avoid jamming @ 9 cubic mm/s: approx. 240 deg C
  • Max recommended volume flow @ 240 deg C: 9 cubic mm/s
  • Min recommended volume flow @ 240 deg C: 1.5 cubic mm/s

Volume flow = extrusion width x layer height x speed in mm.

For example, 0.5 mm extrusion width & 0.2 mm layer height for speed 20-90 mm/s.

Poorly cooled cold sides of all metal hotends can yield a similar result & benefit from similar fixes to the Prusa MK3. Aggressive layer fans not isolated from heat blocks and/or nozzles can make for a jammy combination as well. Finding the balance between enough cooling fan when printing fast & a high enough nozzle set-point can be challenging. More isolated hotends with PTFE liners can allow slower printing with lower set points for more detail with less aggressive layer fan settings. Also, insulating your heater block and/or nozzle with a sock can help avoid unwanted layer fan cooling. Rapid changes in speed or print rate should also be avoided whenever possible.

For more on the subject of printing, consider our getting started guide.

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 crystallization also creates shrinkage. HTPLA parts should be scaled in slicer to compensate for shrinkage when heat treating.

  • Typical heat treat temp: 95-110 deg C (200-230 deg F)
  • Typical heat treat time: 10+ minutes

A large range of temperatures & times can yield acceptable results. With translucent grades and thin wall parts like a single wall vase, you can see a visual change from transparent to opaque begin in as little as 3 minutes with a full transition to opaque in 7 minutes. Parts with more mass will take more time. What's important is the core temp and time to ensure a comprehensive change in material structure to crystalline throughout the part.

  • Typical change in heat treating: -0.6% x/y, +1% z
  • Slicer scale in heat treating:1.006 or 100.6% x/y, 0.99 or 99% z

Here's a demonstration of measuring shrinkage, determining change, and applying compensation in printing. Here's additional demonstration of application of scale, heat treating, and validation of form.

Additional post processes might include sanding or painting. The addition of Carbon Fiber can lend well to ease of sanding and adhesion of coatings like paint, however, there are also additional safety considerations when generating dust through sanding and fumes through coating. Please seek safe practices with appropriate personal protective equipment (PPE) and ventilation.

 

Getting Started with Proto-pasta PLAs including HTPLA

We've created this page to bring you a premium PLA and HTPLA printing experience that rivals our premium material. Follow below to improve your 3D printing experience. In other words, here's your shortcut to awesomeness with pasta. If at the end of this document you have questions or need assistance, please contact us at support@protoplant.com.

Filament Handling

Loose coils can be very tricky to manage. Going cowboy on your spool handling can quickly end up in a frustrating, tangled mess. Keep your loose coils wrangled with a spool holder like masterspool for a more trouble-free experience. Find out more about loose coil handling in Keith's blog post.

And for spooled filament, never let go of the loose end. When not in the printer extruder, tuck it away in the cardboard spool's corrugation! Also, avoid sharp bends and excessive force when loading filament into your printer.

Print settings

At Proto-pasta, we make high quality filament. We aspire to make exceptional results easy, but a positive result is very much dependent on your hardware, set-up, adjustments, and process parameters. Matching hardware with process and material for a positive experience is not always straight-forward, but you can start by pairing the following settings with your printer for a good starting point, then tune or troubleshoot as required.

Example settings for typical printer

  • Nozzle size = 0.4 mm (Standard to most printers & balances detail with productivity.)
  • Extrusion width = 0.45 mm (Typically larger than nozzle size. If using a larger nozzle diameter, be sure to set the extrusion width larger than that nozzle diameter.)
  • Layer thickness = 0.15 mm (For a balance of speed, quality & reliability.)
  • Speed(s) = 15-45 mm/s (Respecting mechanical and volume flow limits. Stay within the recommended speed range but apply slower speeds to the walls and faster speeds to the infill.)
  • Volume flow rate(s) = 1-3 cu mm/s (The result of above speed range, width, and layer thickness. Respect hardware and geometry limitations.)
  • Typical temperature = 215 C +/- 10 C (Matching material, hardware, and volume flow rate.)

Volume flow rate together with temperature dictates how melted the material is. This is hardware & condition dependent based on hot end, nozzle & extruder type, material & manufacturer as well as layer fan type, position & settings. Extrusion width, layer thickness & speed changes affect volume flow which may change required/desired temperature.

Additional settings of note

  • “Grid” infill type at 20-30% - “connect infill lines” unchecked (off).
  • Minimum 3 shells & 4 top/bottom layers for good surface quality.
  • Layer fan set to cool enough for build rate, but not so aggressive as to fail process by over-cooling nozzle and heater block.

Validation and fine-tuning

Post your prints & tag us @Proto_pasta on Twitter and InstagramNeed more help? Consider typical pitfalls and fixes below.

Typical pitfalls

  • Exceeding hardware capabilities.
  • Mismatch of flow rate and temperature.
  • Excessive nozzle cooling from layer fan yielding lower heater block and/or nozzle temperatures than set point.
  • Hardware shortcomings such as MK3 heat break, poor nozzle diameter, or other hangups.
  • Poor assembly or adjustment of components.
  • Excessive retraction distance or number of retractions.
  • Inaccurate flow with missing cross-sections or wall thickness not matching extrusion width software setting.

Typical Fixes

  • Heat break replacement with OEM, straight-through design and defect-free, smooth bore.
  • Proper assembly of components without plastic oozing gaps & with thermal grease.
  • Lightly oiling filament, but careful, a little goes a long way.
  • Reducing layer fan speed and/or isolating from heater block and nozzle.
  • Installing heater block sock to isolate heater block & nozzle from layer fan.
  • Increasing temperature to flow past internal hang-ups.
  • Reduce speed and/or choose a single speed for a single volume flow
  • Consider drive gear tension adjustment, bowden tube coupling/replacement, and spool mounting

Carbon Fiber PLA

Carbon Fiber Reinforced PLA

Our most popular exotic material, prints made with our Carbon Fiber PLA are demonstrably more rigid, providing excellent structural strength and layer adhesion with very low warpage. It has a beautiful matte black finish with a slight sheen due to the embedded carbon.

What is it made out of?

Protopasta Carbon Fiber PLA is made from NatureWorks 4043D PLA Resin compounded with 15% (by weight) chopped Carbon Fibers. It is more brittle than standard PLA in its filament form, so handle it carefully to prevent breakage.
How much stronger is it?
The short answer is that this filament isn't "stronger," rather, it is more rigid. Increased rigidity from the carbon fiber means increased structural support but decreased flexibility, making our Carbon Fiber PLA an ideal material for frames, supports, shells, propellers, tools... really anything not expected (or desired) to bend. It is particularly loved by drone builders and and RC hobbyists.
Print Settings

Because of the chopped carbon, Protopasta Carbon Fiber PLA may have trouble getting through smaller nozzles. We have had good success using a .5mm nozzle and direct-drive spring loaded pinch-roll style extrusion head.Generally, our customers find it prints just like standard PLA on their machines (at around 195-210° F), though others find success running it a bit hotter (around 220° F). Experiment with your printer and see what works best for you.

Density:
1.3 g/cm3 (1300 kg/m3)Parameters:
Bed Temp (if available, is not required): 50° C
Hot End Temp: 195 – 220° C

Carbon fiber and your printer nozzle

The carbon fibers in our filament are processed for an optimum size: short enough to print in PLA without clogging nozzles, but long enough to provide the added rigidity carbon fiber is famous for. At this length, the chopped carbon fiber makes this filament more abrasive than standard PLA. Prolonged use may result in more wear on your 3D printer, particularly lower-end nozzles.
