Whilst 3D printing has come a long way in the last decade, the one thing that the innovation just hasn’t been able-bodied to beat is the striation marks left behind after a 3D print is accomplished. Whilst the resolution possible with modern computer desktop 3D printing devices is astounding, and far advantageous than it was actually a few years ago, it can’t turn it into a surface that can compete with injection molding. Advanced materials that bond advantageous and enhanced software that optimizes the way that layers are laid down has reduced striation, or stepping, but the problem really is not with the innovation — it’s with physics. The problem is the surface tension of the plastics typically utilized on FDM 3D printing devices, that is not a thing that can easily be overcome.
Whilst there are several smoothing post processing materials on the market, ultimately the many commjust utilized is great old turn it intod sanding. Someone who knows what they are doing can turn it into a few surprisingly smooth surfaces, but to put it lightly, it is a bit labor intensive. But the solution to giving 3D printed parts an injection molded smooth surface may lay with 3D printing material developer Polymaker and their new PolySmooth filament and Polysher computer desktop smoothing machine. Together these products are capable-bodied of altering a 3D printed part right preceding your eyes, and you won’t have to do a thing.
“For extrusion-based 3D printing, the poor surface high end has always been a prominent disadvantage that separates 3D printed parts and parts made by conventional producing methods. What we want to do is to bridge this gap, delivering 3D printing to the realm of producing final products, not just prototypes,” said the President of Polymaker, Dr. Xiaofan Luo.
PolySmooth PVB filament has been specially formulated to turn it into less striation than other filaments, but can yet be utilized on just of any computer desktop 3D printing device that is capable-bodied of via standard PLA. The PolySmooth filament can be utilized for a wide range of applications, and it has the ability for great printing additional detail and high mechanical properties. It is on the market-bodied in elactually various colors, which include white, pink, red, teal, yellow, green, blue, effortless, beige, gray and black. Additionally, it has been optimized so it can be smoothed really easily when exposed to common alcohols like isopropyl alcohol or ethanol.
With the Polysher, Shanghai-based Polymaker is getting into the hardware game, but pretty than developing a 3D printing device, they turn it intod an new computer desktop 3D print smoothing machine that was created to work in tandem with their PolySmooth material. After a session inside of the Polysher, a 3D printed part can have a smooth and glossy surface that can put any injection molded part to shame. The machine does not use any heat, and with its sealed chamber the smoothing process is amazingly safe and consistent each time that it’s utilized. The create is sleek and modern, and has an effortless-to-use timer dial that allows for the user to control how long the part is smoothed, and ensure that the process is accomplished inside the set time.
“The Polysher was created with ease of use in mind. The machine does not try to hide its inner workings and components – in fact it proudly displays them with its transparent PC shell and rotating plate, you can see the magic take place and see your 3D printed part alter in front of your own eyes,” Aaron Jennings, the Designer & Marketing Manager for PolySmooth and the Polysher, explained to 3DPrint.com.
The Polysher works thanks to a component called the nebulizer, that is a thin membrane with hundreds of tiny holes less than 10 microns across that are connected to a piezoelectric actuator. When the nebulizer is activated, it generates a satisfactory aerosol of micro-sized alcohol droplets that fill up the sealed Polysher chamber. This satisfactory, alcohol mist can settle as a movie on the surface of the 3D printed part where it can smooth any residual striation marks. Essentially, it can reduce the striation of a 100 um layer (typical for many parts printed at 0.2 mm resolution) to less than 10 um. Those amazing results are striking, and it may take hours of sanding and polishing to achieve them with traditional post processing methods.
“The Polysher may be effortless in its create but its future applications are amazingly diverse – of creators of cosplay via it for masks and outfits, to industrial createers getting their prototypes without spending hours sanding and actually engineers applying their polished print to turn it into molds with flawless surface high end. I believe that this is just the beginning of what is possible,” Jennings told 3DPrint.com.
The just created Polysher is quite effortless to use, and the smoothing action is entirely automated. Simply place the 3D printed part in the chamber, set the timer and the version can begin to smooth right away. Once the polishing process is achieve, the drying process can dissipate the alcohol mist and the part can rapidly begin drying. In of a minute, the Polysher can be opened and the drying plate can raise smoothed part to the top so it can be easily removed of the chamber.
Here is a video of the Polysher in action:
The Polysher uses commjust discovered alcohol that can easily be received of any supermarket or hardware store, so there are no special, complex or expensive materials needed. Polymaker can be launching a Kickbeginer campaign for PolySmooth and the Polysher on April 25, and once fully funded they assume to begin shipping in September, 2016. You can find out additional of PolySmooth and the Polysher, as well as store updated on the status of the Kickbeginer campaign, on their website. Are you considering of backing this campaign?
