What it will not do

• Limited colour range
• Same heated-chamber requirement as ABS
• A few euros more per kilo

What we have learned using it

When a plastic part has broken after years outdoors, it is almost always UV. Remaking it in PLA guarantees it will fail faster than the original; in ASA, it will outlast it.

Consider instead

• PETG — if the part stays indoors
• ABS — indoors only
