K-100: This 3D printer is in a league of its own and still significantly discounted

The Loopzizo K-100 is a so-called SLS printer, which refers to the technique of selective laser sintering. Like a typical 3D printer, the model is built layer by layer, but the material is essentially sprayed on. For this purpose, a laser with an output of 5 watts emits electromagnetic radiation with a wavelength of 450 nm. According to the manufacturer, this allows users to print complex structures, such as those with overhangs, in which case supporting structures are not required. These can also be used in specialized fields such as mechanical engineering. Quickly creating prototypes with this 3D printer is also conceivable.

Prints are said to be heat-resistant up to 120°C, while the torsional strength is specified as 50 MPa. Moreover, the manufacturer advertises a high precision of 100 µm, which means that threaded parts can be printed as well. With outer dimensions of 17.7 x 14.6 x 39.4 inches, the 3D printer is still relatively compact for an SLS system. That said, the build volume depends on the selected mode and material: 120 x 120 x130 mm are available for the production of prints with Polyamide 12, which increases to 130 x 130 x 130 mm when using TPU.

Using this special type of 3D printer shouldn’t be a big challenge for regular users either. As usual, there is a touchscreen for easily controlling the printer, and the production of several smaller components in a single printing process is supported. As part of the ongoing Kickstarter promotion, the Loopzizo K-100 costs at least $5,199 excluding shipping. Lastly, the usual financial risks of investing in crowdfunding campaigns applies here.
