New filament materials are always exciting, but that doesn’t mean there’s nothing left to get excited about with older, more mature and trustworthy materials like PLA. The Stick Filament team certainly saw room for some good ol’ innovation when they developed their filament interlocking system.

By incorporating plug/sheath connectors on the ends of filament sticks, colors can be mixed for multicolor prints. It’s extremely easy to connect them, and their stick format makes storage especially convenient; no need for spools. And it comes in PLA, HIPS, and glow in the dark. For those that are into rainbows and tiedye, Stick Filament is definitely worth a try.

Pretty, eh? There are a couple quid pro quos, though. Currently it’s only available in 3mm; 1.75mm is in beta testing. And I don’t know if this stuff will work with bowden extruders as the retraction would probably pull the pieces apart. Maybe it’d work. I’d try it but my extruder is 1.75mm. If you’d like to try it sample packs containing 75 sticks of PLA filament in 5 colors (15 sticks for each color) with a total weight of 250g are available for about $18. Let me know if you try it.
