Filament Cutter Uses Unusual (But Effective) 3D-Printed Spring Design

When one particular desires a spring, a 3D-printed version is probably not one’s initial choice. It may possibly even be reasonable to say that printed springs are anything just one finishes up building, instead than one thing 1 sets out to use. That might improve when you try the spring style in [the_ress]’s 3D-printed filament cutter with printed springs.

The filament cutter is effective like this: filament is inserted into the product as a result of a person of the pairs of holes at the base. To slice the filment, a person presses down on the plunger. This pushes a blade down to neatly slash the filament at an angle. The cutter is the device’s only non-printed element a solitary phase from an 18 mm utility knife blade.

The springs are of individual fascination, and don’t search quite like a regular spring. They acquire their style and design from this compliant linear motion mechanism documented on reprap.org, and resemble very little parallel 4-bar linkages. These springs have limited journey, but are unquestionably springy ample for the occupation they have to have to do, and which is the critical portion.

Want a a lot more common coiled spring? Annealing filament wound close to a mandrel can yield beneficial results, and really don’t fail to remember the superb mechanisms regarded as flexures they have very clear similarities to the springs [the_ress] used. You can see her design and style in action in the limited online video, embedded underneath.
