Iridescent Ice Clear Translucent HTPLA

Translucent PLA Filament

$5.00 USD


Protopasta'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.

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

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.

Light pipes with Translucent HTPLA

Worked great. Made some little light pipes for using NeoPixels (behind the control panel) to go to the front side on my train club control panel.

Pretty amazing, better after annealing

This stuff is solid in more ways than one. Prints beautifully on my P1P printer with mild tweaking. While there's a little stringing, it torches off with a lighter to a smooth finish. While the stuff prints 'clear', once annealed, it is brilliantly tough, and works perfect as a translucent diffuser for lamps, ARGB leds, and a lot of other bits. If you were wondering, for perfect results and no deformation - print the part solid (i.e., solid layers, no infill), in a 6x6x6 inch food service pan or similar; pack the printed part in flour salt. The pan will hold around 6 lb (or three 2 lb. bags) total. Put the whole thing, part, salt, and pan, in the oven for 2 hours at 230 F (110 C) to get the whole part annealed. The 2 hours is necessary, I did 1 hour and the center of the salt pan didn't get warm enough, so the center of the part didn't anneal, so shoot for 2 hours or more. Comes out perfectly translucent and rigid, dimensional deformation was less than 0.2-0.4mm on any axis.

Perfect frosty clear

Because it becomes less transparent when annealed, I like to use Iridescent Ice for printing LED diffusers for electronic projects and models. The "frosted glass" effect looks even better when printed on a textured surface. For the smaller, flatter parts I usually just heat treat right on the bed by setting the bed temp to 110C for a few minutes after the print is finished.
