Silver Smoke Grey Translucent HTPLA

13 reviews HTP2170-SMK

Regular price $4.50 USD

HTPLA out performs PLA, ABS, and Polyesters like PET!

Proto-pasta's HTPLA v2.0 is better than the original kickstarted version. This new formulation is higher performing and lower cost. HTPLA prints similar to standard PLA but is "Hella Tough" and can be "Heat Treated" for "Higher Temperature" resistance. This durable PLA has a theoretical Heat Deflection Temperature (HDT) of more than 140C (285F) after heat treating though in our experience 120C or more was practically attained.  This means HTPLA parts maintain strength and form to much higher temperatures than PLA, ABS, or Polyesters like PET which loose structure as soon as 55C and by 100C.
How do you "Heat Treat" for maximum performance? Bake your parts into a oven until you see a change from translucent to opaque. Yes, there is an obvious visual change indicating the improved performance! We had good luck in a lab oven at 110C (230F) for an hour or less. 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 can be baked at a lower temperature (though must be above 60C for any change to occur) for a longer time with less risk of unwanted deformation.
  • Available in 1.75 & 2.85 (3) mm diameter
  • Colors include Iridescent Ice & Silver Smoke
  • 500g 8" diameter spool only

No abrasive fillers so expect normal wear with standard nozzles.

In our experience, good results were achieved using standard PLA parameters with standard build surface preparation (blue tape, glue stick, or BuildTak). No heated bed required.  Some shrinkage and distortion may occur in the annealing process, so larger or dimension critical parts may need to be scaled larger to compensate or printed in our more stable, lower shrink Carbon Fiber version.

Benjamin K. verified customer review of Silver Smoke Grey Translucent HTPLA
Prints with ease, looks great.

This filament prints really smooth. I used a .25 .4 and .6 nozzle for a few different projects and had no issues. Very strong after heat treating, with some distortion - this is clearly stated by Proto-Pasta but the distortion isn't that bad. Try printing something in vase mode and put some LED light strings inside the print, great aesthetic. One word of advice, if you use a glass bed the bottom of your printed models will be very clear. This was great when printing a replacement face-plate for something, but wasn't as great for thicker models printed face down where I could see the infill. I think I'll make sure I always have a roll of this on-hand. For any projects that use lights, this will be my go-to.

Perfect really don't see the Grey in the print until the 6th layer
