For all 3D printers , the layered marks on the surface of the print made by extrusion technology are the most troublesome because its presence greatly reduces the quality of the print. But now, this pain point will be eliminated, because Shanghai 3D printed wire manufacturer Polymaker has launched a special processing device Polysher. It sprays a special alcohol aerosol onto the print, eliminating layered marks on the surface of the print, significantly improving surface quality and making the print as smooth as a high quality injection molded part. Here is the processing of Polysher:
It is understood that the entire process can be completed in only 20-40 minutes, as the effect is very good, the roughness can be reduced by at least an order of magnitude, so that the surface of the print becomes as smooth as glass, and no delamination marks are visible at all. In addition, after the treatment is completed, Polysher also performs a drying process to disperse the atomized alcohol.
Alcohol atomization schematic
This magical effect is achieved with Polysher's sprayer. It consists of a film and piezo actuators filled with hundreds of small holes less than 10 microns in diameter. In operation, the sprayer atomizes the alcohol spray into uniform droplets less than 10 microns in diameter. They quickly adhere to the surface of the print and dissolve the protruding portion of the print layer, making the surface smooth. In addition, Polysher is equipped with an automatic lifting platform and closed processing, so the pickup is very convenient and safe to use.
It all looks simple, but it works best with PolySmooth.
Performance comparison between PolySmooth and PLA and ABS
Briefly introduce PolySmooth. This wire prints at 190-210 ° C and does not require a heated print station. It has a good adhesion. If the fill is set to 100%, the mechanical characteristics of the print are comparable to PLA or ABS prints. In addition, its tensile strength and impact strength are higher than those of the conventional materials.
But more importantly, PolySmooth is easily post-treated with ethanol (alcohol) and isopropyl alcohol, both of which can be used in Polysher and are readily available.
According to Polymaker's disclosure, Polysmooth wire will soon be mass-produced. At the same time, Polysher's R&D has been completed 80%, and it should not be available anymore. On April 25th next week, the company will launch the corresponding Kickstarter crowdfunding. The total price of Polysher+Polysmooth is $199. If you are interested in them, please keep an eye on it!
