3Doodler, the first 3D pen has been marketed since early 2014 following a call for participation via the Kickstarter website. In addition to a 3D pen, the kit offers plastic threads (ABS or PLA), material that as an ink fits into the pen and allows you to create objects in 3D. The plastic is heated to around 250 ° C, which allows it to be molded at will before it becomes solid, a few moments after coming out of the pen mine. It is possible to draw on a flat support and to assemble the pieces later or to draw directly in the void, by hand movements, provided that the structure rests on a base. Thus, for small creations, this process avoids not only the technical phase of design of the object in digital format but also the long phase of printing.See best filaments for 3d pens in 2018
Creations more fragile than with a printer
The strength of the result of a creation can be deplored by using a 3D pen compared to that obtained with a 3D printer. And this defect is directly attributable to the material, since for the moment, the device of the 3D pen only works with certain plastics. A 3D pen pack + plastic threadcosts 90 euros and the completion time is 30 seconds to 1:30 depending on the object created. One hour of manipulation is enough to master the technique and easily create all kinds of small objects. For now, unlike 3D printing, such a pen does not offer the possibility of repairing anything or recreating a missing piece, unless it has only one role accreditation. It is used instead to create more or less functional play objects such as frames of glasses, or figurines for decoration.
A promising future for the general public
The professions related to artistic creation are initially targeted but like any new invention, the 3D pen is likely to evolve both in its structure and its uses. Moreover, a new initiative launched by the English startup Lix Pen Ltd on Kickstarteraims to make the 3D pen easier to handle. The Lix 3D Pen, much less wide than the 3Doodler, looks like a simple pen, has a modern design, works quietly and is powered by USB power. The first deliveries of the project supporters are planned for May. The rapid evolution of the shape of the tool reflects the expectations of the public: little by little the use of the 3D pen will be closer to the uses of 3D printing today, more functional. This development will benefit the general public because 3D creation with a pen is more manageable, and therefore more accessible, both technically and financially.
