Today, a few words about the weaknesses of 3D printing, or rather their "extinction". Well, the main drawback of 3D printing severely limiting its use, for example in the industry is that print has a porous structure, and thus need additional treatment to be sealed. In other words, in an article printed 3D printers can happen micro slits that pass liquids. Horizontal stripes on the walls of the models is the domain of low-cost incremental technology. Due to the most common range of height of the layer of at most 0.1 mm to 0.3 mm, they are most visible in the case of FDM technology. Smoothing their sleepless nights not only the most ardent aesthetes, but also those who print in this way the finished products.
Methods to obtain a smooth surface of the 3D model is a few. We can choose both the mechanical processing and chemical. Mechanically we printed our object, for example, sandblast or grind, in the case of chemicals we can use them to interact indirectly through acetone vapors, or directly covering the surface of various substances. Each technique has its pros and cons. Machining requires a lot of time and effort, and chemical treatment adversely affects the reproduction of the smallest details, making it become less pronounced.
The method developed by the Japanese
Scientists in Japan have developed their own method, which does not require much effort, or does not reduce the detail of the 3D model. They called it Chemical Melting Finishing 3D (3D-CMF). It involves using a special pen tip reminiscent brush. Thanks to the surface is applied a thin layer of a chemical agent which does not function as aggressive as for example acetone. With such a
All tests have been focused so far on FDM technology, because it is the most widespread, especially among non-users, and above all, however, is the method in which this problem is most visible.
The main advantages of using 3D-CMF hut is tedious necessity of removing the bands by their resistance, which in a small degree also contributes to lower material loss, otherwise the amount of chemical used is much smaller than traditional methods. Thanks to the tips of various sizes we are able to suit a particular type of surface.
Although so far there is no information on the commercialization of new technology, 3D printing smoothing it, it could become an ideal compromise between mechanical and chemical treatment.
Zortrax Apoller - a system for automatic smoothing of 3D printing?
Zortrax introduced a new hardware device - equipment for automatic smoothing output of thermoplastics.
And so it looks smooth element of just leaving the p device.
For now, so we can smooth certain types of filaments, but it seems to me that the question of the future is to find a way to smooth and seal micro slits in each of the possible printing materials. When writing this post I suggested in large part to the materials found on websites such as:
Apoller is an intelligent device which allows automatic smoothing models made with 3D printers selected thermoplastics. The final effect of smoothing is nothing new - for many years, this process is used by many amateur low-budget 3D printing, however, the way to this approach, in many cases leaves much to be desired in terms of health and safety rules (or rather their complete lack of ...).
Apoller was based on its own proprietary technology, smoothing - The Smart Vapor Smoothing (SVS). Working chamber of the device is 300 x 250 x 250 mm and thus is able to accommodate the vast majority of the details printed on the top, desktop 3D printers of type FDM / FFF. The chamber is airtight and double-sealed, which eliminates any risk of accidental chemical vapors to escape to the outside. The paper uses acetone or MEK, which are stored in tanks embedded inside the device. 300 ml of solvent sufficient for several hours. The process is fully automated and takes a total of three hours, thereby a day Apoller details can smooth the resulting four 3D printers, a standard working area (20 x20 x 20 cm +/- 3 cm).And so it looks smooth element of just leaving the p device.
