Omni Dynamics, a British startup, is introducing what they call Strooder, the "first truly consumer oriented filament extruder for 3D printers."
"The overall aim for Strooder was to create a product that not only performs better than anything else on the market, but that also has a design which fits in a multitude of environments, ranging from workshops, to home offices, and even schools," say the crew at Omni Dynamics. "A key difference of Strooder in comparison to other filament extruders, apart from its stunning looks, is its user friendliness."
Strooder, which features a 2.4 inch color screen which has been preloaded with a raft of extrusion settings for a variety of different plastics, enables novice users to extrude filament easily, and for more experienced users, the preloaded settings can be edited or set manually.
The team at Omni Dynamics, a group of robotic engineers, know the importance of an easy to operate user interface. To create that user friendly design, Strooder is the only extruder on the market with a full color display which is pre-loaded with all of their recommended settings for each material.

Dooley says the overall aim in creating Strooder was to realize a high performance product made to fit into a multitude of environments from workshops to home offices and schools. Strooder uses a tried and tested feed screw mechanism to turn inexpensive pellets of plastic into quality filament. The pellets are forced along a tube to be melted and pushed out through a die where, once they're "strooded," the resultant filament is cooled and formed into a solid material.
Pellets can be bought at only a fraction of the cost of traditional, pre-made filament (up to 5 times cheaper) and Strooder transforms them into filament via a product safe enough to be used by anyone by eliminating any exposed parts, using sensors to detect overheating and taking advantage of their active cooling system. Current nozzle sizes include 1.75mm, 2.85mm and 3mm, and Strooder can extrude almost any plastic such as PP, PET, HDPE, HIPS and PE.
You can get a fully-assembled Strooder through their Kickstarter Campaign for around $385, and that commitment also nets you 5 kilos of pellets to make your initial batch of filament.
