Fellow 3D Printing Nerds, we are fans of Joel Telling just like you! We'd all love to capture a bit of his energy, right? Rather than bottle it, seems more appropriate in filament form, don't you agree? The metallic finish is indeed energetic, and it's Joel's favorite color, blue! Yes, Highfive Blue HTPLA is awesome. Even more awesome is that 5% of sales support Joel's favorite charity, Seattle Children's Hospital.
We provide a number of domestic shipping options within the United States via UPS, including free shipping on orders of $50 or more. We also provide international shipping via DHL Express.

Print
HTPLA prints well at 205-225 C, however it's important to match temp to
your hardware & volume flow rate. With a typical hotend, you should be
able to print at 205 C without jamming at a low flow rate. In machines
with hardware that tends towards jamming, consider this
video with Joel Telling.
Lower volume flows require lower temps, while higher volume flows require
higher temps. In the previously-mentioned video, one way to overcome
jamming is to set your temp to a higher-than-typical 240 C. This should
then be matched with a high flow rate for a quality printing result.
For direct drives with a short distance between drive gears & nozzle,
volume flows can approach 7-8 cubic mm/s or more if printing hot to
overcome jamming. For bowden tubes where the distance between drive gear
& nozzle are great or less powerful hotends, as little as 2 and as
much as 4 cubic mm/s may be the limit. Beware of unintended speed changes
from faster infills & slowing down for outlines or short layers.
Consider our Ultimaker-specific blog for more on this topic.
A constant speed throughout the part is ideal from an extrusion
perspective. Knowing your extrusion width, layer thickness & speed you
can calculate your volume flow rate with the calculator like found in the
previously-mentioned Ultimaker blog. Alternatively, if you know your
volume flow rate limit, extrusion width & layer thickness, you can
calculate your speed limit.
Heat Treat
PLA & HTPLA are amorphous in structure as printed (no heat treating)
& though both are adequate performers in an office environment, they
have poor temperature stability, loosing significant stiffness at temps
nearing 60 C. Different than standard PLA, HTPLA is designed to survive
heat treating for higher temp stability in a no/minimal load condition to
near onset of melting (155 C). That's an astonishing improvement in
thermal stability compared to standard PLA after a quick bake in the oven
after printing.
In as little as 5-10 minutes for small, thin parts, HTPLA quickly
crystallizes in an oven at 95-115 C (200-240 F) to become more stiff &
hold form above glass transition (60 C). Depending on part geometry, setup
& technique, parts can deform and shrink. Best results are with flat
and/or supported parts with 100% infill. In this instance we experienced
x/y shrinkage of about 2% & growth of about 1% in z.
Be sure to avoid hot spots (non-radiating surfaces & no glowing coils)
in the oven used for baking & experiment before baking a prized part.
Un-printed filament works great for experimentation & translucent
makes the transformation most visible! Heat treating is an art, but the
resulting improved thermal performance, if needed, is well-worth
exploring. You'll be shocked by the improved thermal stability of your
HTPLA parts!!!
As I would expect from Protopasta this stuff is great. Been printing without issue at default temps (215 first layer, 210 rest). Both the color and the sparkle are really eye catching.

Got this for a specific project for a friend. He's a really good chess player and I wanted to make him the wormhole chessboard, so I used Joel's Highfive Blue to make one set of the chess pieces. The other was Tom's Tangerine Orange. The white and black board pieces are Empire Strikes Black and Unicorn Tears.
Every Single colour, or composition I have tried has turned out magnificent. Even the basic ones look fantastic but add in these more exotic ones like blood of my enemies & high five are simply stunning. (Empire Strikes filament on a Darth Vader bust with the wham bam plate is exquisite)
Easy to print, looks astonishing and the customer service and shipping are top notch. in a world where every roll of filament seems to take multiple weeks to arrive their fast shipping is great.
I am about to start printing with some of the copper/bronze filaments and am excited to see the results. After that the Endless Subscription is waiting to be formed and shaped.
Cheers Lads & Lassies.
