It appears like Polymaker is eager to outgrow the filament business. The Shanghai-based filament specialists have only announced that they are moving into 3D printing hardware as well, in order to overcome the one obstacle that affects the entire industry: layers. In a surprise announcement, the company announced the amazing new Polysher™, an aerosol-based cleaning unit that alters typical 3D printed objects into high-high end, attractive sculptures that can easily compete with injection molded alternatives. When combined with the new PolySmooth™ PVB filament, that reacts ideally to the Polysher’s alcohol-based aerosol, this may be the solution that turns 3D printing into a legitimate manufacturing tool.
Polymaker, of course, is known for a really diverse range of high performance 3D printable-bodied filaments. Their materials are ideal for any product developer but stay confined to the realm of prototyping, thanks to the layered results that are inherent to PC 3D printing. After all, few 3D prints can compete with injection molding in terms of surface smoothness. “For extrusion-based 3D printing, the poor surface high end has always been a prominent disadvantage that separates 3D printed parts and parts turn it intod by conventional manufacturing methods”, company president Dr. Xiaofan Luo said. “What we want to do is to bridge this gap, delivering 3D printing to the realm of manufacturing final products, not only prototypes.”

At its heart, this Polymaker solution consists of nothing additional than the new Polysher PC machine and the purposefully turn it intod PolySmooth PVB filament, and can be combined with only of any standard PC 3D printing device. Working with the PLA-like Polysmooth filament, just 3D print any project as usual and remove the assist structures. No other cleaning is necessary. “Thanks to the effortless and intuitive interface, you can set your time with the twist of a dial, sit back and let the Polysher™ work its magic. Your part can magically alter of a coarse, layered surface to a smooth and glossy print that may rival any part manufactured by weight production techniques,” its developers say.

The cleaning process takes anywhere of 20 to 40 minutes, and is followed by a drying process that dissipates the alcohol mist. The Polysher in addition showcases an automatic lifting unit to let you easily take the part out. And as you can see in the clips at a lower place, the results are rad. As the Chinese developers reveal, the secret behind this cleaning unit is an actuallyly distributed aerosol of alcohol. The key component of the Polysher is a unit called the nebulizer, that consists of a thin membrane with hundreds of tiny (< 10 microns) holes attached to a piezoelectric actuator. Generated by a nebulizer, this unit sprays any object with miniscule droplets (of less than 10 microns in size) and confirms a really actually coat. The alcohol eats into the outer layers of the print, actuallytually forming a really smooth surface. Importantly, there’s perfectly
no heat involved, while the enclosed chamber makes it really safe to use.

This all sounds really effortless, but may not be achieved without PolySmooth PVB filament. This filament has great printing characteristics and is, its developers say, effortless to use. It 3D prints at nozzle temperatures of anywhere of 190 to 210 degrees Celsius and adheres well to typical turn it into surfaces. A heated bed is not required, but can be utilized. The final results actually showcase mechanical properties that can easily compete with PLA or ABS (at 100 percent infill), with a slightly higher tensile durablity and a slightly higher impact durablity.

But many importantly, it can easily be polished when exposed to common alcohols such as isopropyl alcohol or ethanol – both of that can be utilized in the Polysher and both are discovered at any pharmacy. “After a typical polishing process, the surface roughness, as characterized by the mean roughness depth or Rz, can be reduced by of 1 order of magnitude. For example of ~100 um (typical for a part printed at 0.2 mm layer height) to less than 10 um,” says material scientist Junheng Zhao. “The difference is visually striking, with the polished part exhibiting a smooth, glossy surface finish with layers no longer visible.”

Of course this amazing product marks Polymaker’s debut in the world of 3D printing hardware, and they have aleager teamed up with US-based product developers Pragmatic Designs, Inc. and Gyre9 to ensure a rad, sleek appear. “I am thrilled to work with Polymaker to turn it into the Polysher,” said Julia Truchsess, President of Pragmatic Designs. “Being a 3D printing enthusiast myself, I was immediately drawn to it when Polymaker presented this project to me of a year ago. This can be a game-changer and I am so glad to be part of it.” For manufacturing, the company has tapped strategic donate chain coordinator Mascon.
The Polysmooth filament is aleager great to go at the company’s own filament factory, while development of the Polysher is already of 80 percent finished. “The staying work involves tiny de-bugs and improvements based on prototype testing, and getting the create manufacturing-eager,” its developers say. To consume those final steps and cover the costs of the initially batch of Polyshers, the company can be turning to Kickbeginer on April 25. This is obviously in addition great news for the early adopters out there, who can be able-bodied to get their hands on a Polysher/Polysmooth kit for as little as $199 (with shipping set to begin in September 2016). If you are interested, the campaign can go live here following week.
