Recently at the Vancouver Maker Faire, I was talking with the CEO from
RP Electronics and convinced him that he should stock more colors and sizes of their filament since they only ever had 3mm ABS in a few colors in stock. Looks like they took my suggestion to heart as I was by today and they seemed to have a ton of spools in stock available.
MG Chemicals (a good friend to many 3D604 folks with their local support at Maker Faire and various hacker/makerspaces around the region) has a lot of new options in stock at RP now:
including the 250g spools of 1.75mm PLA in just about every color imaginable.
It's definitely not the cheapest available but it's been very consistent (they also have posted the MSDS for the filament) and you can pick it up in store in small spools for those jobs where you only need a little of that weird color. They also have 500g and 1kg spools.
This isn't an ad nor a paid endorsement....just thought I'd share what's available locally from suppliers that seem to genuinely care about their customers.
