3D printing prevent curling and curling solution summary [Hong Rui 3D Printing]

Melt Stacking Technology FDM printers use high-temperature melting pla/abs and other environmental protection plastic to build up layers, but in the process of melting and cooling, there is the problem of the corner of the printing object, which is 3D printing the most headache problem, may be due to uneven platform or shaft slightly bent, so that the material and the floor is not easy to bond, The first layer is always unable to print, or after printing a few layers to find the warping phenomenon. So how to prevent warping or first layer non-stick and problems?
1, the most efficient way is to buy a frosted glass, 3MM thickness is the best, if the 2MM and 5MM are too thin and too thick heating uneven and blown up, as far as the size of your platform to match. If the platform with heating function, it is recommended to use frosted glass, temperature heating to 70 degrees, the effect is very perfect.
2, another method is directly in the market to buy a kind of called 190 light oil, the price is very affordable, is self-painted kind. But do not spray directly to the platform, to buy a transparent glass, after spraying the effect. If the platform does not have heating function, it is recommended to use 190 varnish, spray onto the transparent glass, and so on after the use of dry.
3, if the nozzle and platform spacing is not uniform, when the small, then with the minimum spacing, you can spray nozzle and platform does not matter, because it is glass, not bad, also does not affect printing adhesion.
If you can not prevent the printing edge of the problem, then we need to find how to solve the edge of the way, a lot of methods, now the main list of several ways to solve the problem of warping.
1. No hair.
Briefings let print speed up cooling. If the print is too small, too late to cool will begin to print a layer, which will lead to the collapse of the occurrence, need to blow to accelerate the cooling. However, when printing larger works, the cooling effect of the blow will make the plastic shrink, resulting in inward tension, causing the edge to rise. Fortunately, the work of large, single-layer printing time is longer, there is enough time for the plastic cooling, do not open the fan-blown workpiece can still have a good print quality, but also reduce shrinkage caused by warping.
2. Use of hot bed
Theoretically, the hot bed can maintain high temperature on the bottom and reduce the warping caused by shrinkage. But is not able to guarantee 100% not to tilt the way.
3. The first layer of line width widening
The wider the line width, the more material is extruded from the extrusion hole, and the stronger the strength of the plastic and printing table presses. This can increase the adhesion of the work to the printing table, thereby reducing the condition of the edge.
4. Some models for the edge itself has a better way to avoid, with the nozzle, add heat, material related
