Our Thermochrome Grey EcoPLA filament is a revolutionary new color-changing 1.75mm PLA filament. This Thermochrome Grey EcoPLA filament has an opaque anthracite grey colour when the temperature of the material is below 29c. However, when the material reaches a temperature of 29c, or above, it will change into a transparent color.!

This amazing Thermochrome Grey EcoPLA filament is part of our EcoPLA 3D printer filament range and is produced and extruded in the Netherlands. The complete process from sourcing the chemical recipe to the actual extruding of the Thermochrome EcoPLA filament is being done in the Netherlands. This reduces the travel distance of this material significantly, meaning that less fossil fuels are being used to get this material into our warehouse.

Thermochrome EcoPLA, like normal PLA (Poly-Lactic Acid in full), is a thermoplastic which is extruded from the starch of plants, such as corn, cassava, sugarcane, cereals, or sugar beet. By being derived from biological resources this type of thermoplastic can be biodegradable under the right conditions (such as an active compost heap, with enough presence of oxygen) and therefore has a much lesser environmental impact than thermoplastics derived from fossil fuels.

Main differences between PLA and Thermochrome EcoPLA filament
Our Thermochrome EcoPLA prints just like normal PLA. The only difference is that an additive has been added to our EcoPLA which enables this colour-changing feature. You will find that printing with our Thermochrome EcoPLA will go just as smoothly as printing with our normal EcoPLA.

General Tips & Tricks for printing with PLA filaments
The printing temperature guideline for printing with our Thermochrome EcoPLA filament is approximately 210c. As each desktop 3D printer has its own unique characteristics, you might need to tweak around with your temperature settings a bit to get the best results. To obtain optimal results for your prints you need to take into account variables like your 3D printers nozzle diameter, your printing speed settings, and layer height.

PLA has much less tendency to warp compared to ABS. Therefore it can be printed both with and without a heated print bed. However, if your desktop 3D printer does have a heated print bed it is recommended to set your print bed temperature to approximately 40c to 50c.

A good first layer adhesion is of the utmost importance in obtaining the best results for your prints. There are several tricks to get the first layer of your PLA print to stick better to the print bed of your 3D printer.

  1. Blue Masking Tape. PLA prints usually stick really well to blue masking tape. When preparing the print bed it is better to have tiny gaps between your strokes of masking tape, rather than having overlaps. Overlaps of smaller pieces of tape may cause difficulties later on during the print process.
  2. We have tested a wide variety of masking tapes and found that the best results can be obtained with Eurocel Blue Masking Tape.
  3. Coat your print bed with hairspray. Like ABS, PLA has a tendency to stick really well to extra strong hairsprays.
  4. Blue masking tape is unlikely to leave a residue on your print bed. A hairspray coating however will leave a residue on your print bed.

What Temperature to 3D Print your Filament at?

While each 3D Printer is different and you will need to play around with the temps to get the best print here are some starter temps for you; these are all temperature profiles that are verified and confirmed print temps on the 3D Printers (9 different machines from pre-built D3 and D4 to our own DIY custom Reprap printers) with the actual filament we sell to you... so they will get you 99% of the way there!

195c - 210c
210c - 215c
230c - 235c

175c - Smooth
210c - Rough

165c (light colored wood)
210c (very dark colored wood)

How do I get my filament to stick and STAY stuck?

This one is a multi-faceted answer but here are the basics:

  1. Your print bed has to be level!! I mean, spend some time on this one... if it isn't level like a... well... like something that's really level - then your print won't stick and it won't come out looking right.
  2. Next... CLEAN, CLEAN, then RE CLEAN, have a sandwich and a soda-pop and then CLEAN again... use acetone and a lint free towel to make sure your print surface is clean and free from oils and dirt.
  3. If you are having a hard time printing on glass try using some Kapton tape as that will give you a little better stick
  4. If you have a heated print surface... TURN IT ON!! Even when the filament used might not call for it, I always turn on my heat bed (who doesn't like a warm bed!!); even if it's just 40c it will really help. For PLA normally you'll want about 60c and for ABS you'll want 110c
  5. For ABS 3D Printing room temperature really matters... you need to keep your entire build warm; so if you can't print out in a warm room try putting a box over the printer to keep that build area as warm as possible.
  6. Try making "ABS Juice" - just add some scrap ABS filament to a bottle of acetone and let it dissolve and then use that to clean your print surface as normal; the dissolved ABS will give your printer extra STICK OR you can use "Aqua-Net Super Hold" hair spray (must be this brand to work right)... just clean your board as always and then lightly spray the Aqua-Net on the print board and print away (this method is my favorite as it seems to work best for me!)
  7. KEEP trying!! You'll get it and once you do have it dialed in then you have it forever... each printer is different; make sure you make notes of what works and what doesn't for each filament you use and each printer you have. So, in the future when you want to print out that EPIC "Yogi Bear" figurine in Blue you know what to set up your GCODE for.

What is the main differences between PLA and ABS 3D Printer Filament?

The main difference between PLA filament and ABS filament is that ABS is produced from fossil fuels and PLA is derived from biological resources, which makes PLA plastic biodegradable. Check out this 3D Printing Filament Impact Test -- PLA vs ABS vs PETG vs Sledgehammer (click here to watch the videos)!! When it comes to 3D printing the key differences between ABS and PLA are:

  • PLA is a rigid liquid and ABS is a crystallized liquid, meaning that when heated ABS transits slowly from a gel to liquid and PLA transits direct from solid to liquid.
  • ABS is more flexible and PLA is more solid, meaning when stressed PLA will snap sooner.
  • PLA is more glossy looking consumable than ABS (see photos when selecting your material).�

Wow, you have a 1kg spool of filament... SO What! How much actual filament is that??

Big question of the day is... how long is a spool of 3D Printing Filament!? Hummmmm, I think even Blinky the wise old owl might have a hard time with that question but never fear... we have the answer!!

1/kg Spool

PLA 1.75mm

PLA 3mm

ABS 1.75mm

ABS 3mm





... and what does that mean to me and you!! Well, check this out... if you are printing with 3.00mm filament for a iPhone case you need about 2,700mm of filament; for a EPIC Starship Enterprize Model you'll need about 12,000mm of 3D Filament and for a full Kossel 3D Printer Kit we normally use about 50,000mm of filament. Another way to look at it according to MakerBot is that 1 spool of 3D Filament produces about 392 full sized chess pieces. Whoa... that's a lot of chess!!


Don't forget... Print Happy @
Now, go tell 5 friends and 3 total strangers that is beyond EPIC!!! (thank you)
