Technical Data Sheet




3DTomorrow Astro PLA Filament

Looking to create prints that are truly out of this world!? Then look no further, our Astro range of filaments contain metallic flakes that gives prints a sparkly, celestial finish. As an added bonus, this glitter effect reduces the visibility of layer lines and the modifications to the PLA result in a tougher less brittle material.

PLA (Polylactic Acid) is one of the most commonly used 3D Printing filaments, chosen for its good value, ease of printing and bio-based production. 3DTomorrow’s Astro PLA is supplied on a cardboard spool, which are 100% recyclable, so this product can help you reduce your carbon footprint vs buying plastic spooled alternatives.

What to expect from 3DTomorrow Astro PLA?

As a print service ourselves, we know that filament quality is of upmost importance and would never sell a product that we would not use. Our Astro PLA filament can be used to produce excellent quality prints, thanks to great interlayer adhesion, low warp and tangle free spooling. Another great thing about our filament is the consistent strong colours, which ensure colour match even if you have to change spool midway through a batch.

3DTomorrow Astro PLA is vacuum sealed with a desiccant directly after manufacture, so you can rest easy knowing your filament will arrive in good form. We pride ourselves when it comes to environmental best practices and quality assurance, you can read more about this here.

Print Settings

While not explicitly required, a 0.5mm extruder nozzle is advisable as this will prevent build up of metallic flakes. Purging the extruder when changing material is also recommended to remove any metallic flakes from the nozzle and prevent build up.
