3D Printing & Using NASA Space Wrench Here on Earth
9,804I 3D print the wrench designed for the ISS commander Barry Wilmore (AKA. Butch) designed by Made In Space & NASA. This is the first tool 3D printed in space! I use both PLA and colorFabb XT Materials to test there strengths and weaknesses and I was really surprised!

ColorFabb XT filament is produced from Amphora 3D™ Polymer by Eastman Chemical Company.
Clear amorphous copolyester filament for 3D Printers
Effective Diameter
1.75 mm +/- 0.05 mm
2.85mm+/- 0.05 (will work with any 3mm printer, but awesome for Bowden printers such as Ultimaker)
1 Spool contains min. 750 grams of filament
Processing temperature = 230 – 260 degrees C
Please read this:
Switching back to PLA or another material is usually done by ‘purging’ the hot-end of _XT material. Heating up the hot-end to 240 C and feeding through new material will purge the hotend of _XT. Another method would be to insert filament manually in the hotend (while hot) and retracting it immediately. _XT will stick to the end of the filament which can then be cut off. Repeat this several times to completely clean out the hot-end. Ensure hot end is completely purged prior to starting prints with the new material.
And what is ColorFabb_XT
The ColorFabb_XT range is a special amorphous copolyester with a Tg of 75 C. So you can use this up to 70 degrees C. Toughness is high. Elongation at break = 50% (yield). In comparison, the normal PLA / PHA range has a elongation of approx 10% at yield, but has very good layer adhesion properties and is a bit softer compared to PLA. Both qualities have minimum warping tendencies.
In addition to this, ColorFabb XT is very transparent and odourless compared to ABS.

Questions & Answers
Q) Why didn't you print it in Bronzefill?
A) The bronze filament is bronze dust held together with PLA so it's actually weaker then PLA by itself so it would have been pointless. Email business inquiries to Barnacules@barnnerd.com Help the channel by donating BitCoin to 1MfVZVMjfUUq8srg1d4RbgXR5e7JLw7R6P
