colorFabb VS. Proto-pasta – Which one should you get first?
So, during the development of DSLRigger, my Open-source camera project I worked with carbon fiber filaments and got two different deliveries. I wasn’t sure on which one to use so i decided to to a proper test of them.
As you can see in the video above, the result was pretty similar. Sure, one is easier, but the other one adds some extra functionality due to it’s recipe.
I hope you enjoy the test. Drop us a comment if you have any questions at all!
The test includes the two following materials:
colorFabb XT-CF20 and Proto-pasta HTPLA – Carbon Fiber
The result (as you can see in the video) is very depending on the actual settings you use. For me, I fel that the Proto-pasta filament was so much easier to use and the result felt as strong as needed. The parts i’ve printed have been very resistant to pressure and wear. Some of the parts on my camera rig is clamping rods, and the filaments both resists high pressure for long duration, even with stress involved.
colorFabb XT-CF20 is a copolyester based carbon fiber composite material that is based on the unique Amphora 3D polymer from Eastman Chemical and is loaded with no less than 20% specially sourced carbon fibers suitable for 3D Printing
- Extreme High Flex Modulus (6.2 GPa) / twice as stiff as PLA
- Moderate strain at break (8-10%), so no extreme brittle filament, but toughness
- High Glass Temp. (Tg = 80C)
- Very high Melt strength
- Very high Melt Viscosity
- Good dimensional accuracy and stability
- Low odor / Styrene Free solution
- Easy processing on many platforms
- High attractive matt black surface
- Easier and more reliable printing
- No heated bed required
- Lower processing temperatures, like standard PLA
- Less warping and distortion when processing
- More temperature resistance* for maintaining properties to higher temperatures
- Most ABS, PET, and Polyesters get soft at 80C +/- 10C
- HTPLA-CF maintains properties up to 120C or more (*when heat treated)
- Higher strength and better strength-to-weight ratio for stronger parts with less material
- Improved surface hardness for less wear in abrasive environments
- Less shrinkage and distortion for more accurate parts
- Higher stiffness so parts hold their shape
- Renewable biopolymer with low odor
- Highly desirable black finish
HTPLA-CF, like Aromatic Coffee, is based on our High Perfomance HTPLA v2.0, so it prints easily and can be heat treated for higher temperature performance with a potential Heat Deflection Temperature (HDT) in excess of 140C (285F) depending on processing. We had good results when heat treating in an oven at 110C (225F) for an hour. We recommend leaving the supports on your parts, placing them on a non-radiating surface (like glass, ceramic, or composite), and letting them cool in the oven to minimize distortion. Parts must be baked above 60C for any crystallization to occur.
