For a perfect item from the 3D printer, the original must match. These tips will help you.
3D printing is a wide field, according to printerhall. Different printing materials are used – from plastic to wood to ceramics or metal. Not all materials work well with your 3D printer at home. For this reason, service providers offer printing in stainless steel or ceramics, for example. A properly prepared print template saves you anger and ensures a successful print result.These tips will help you.
Material Adjustment: Each print material reacts in its own way, hard materials other than flexible, light other than heavy. During the printing process, materials expand and coalesce when cooled. If you are planning an object in metal or ceramics, it is advisable to avoid sharp corners. Round off them in the design of the print template in the CAD program to avoid trouble with the final result.
At the same time, the print material also sets limits in detail accuracy. If too little subtleties are installed in the 3D template, they are often lost in the finished object or do not stick and break. Some printing errors can be revised in the post-processing by filing and grinding. For precious materials such as silver or gold, however, you do not want to lose one gram after the pressure. Therefore, the template should be perfect from the beginning.
Observe the installation space: The size of a finished object depends on its function.Parts such as screws or buttons for the car or household must have an exactly fixed size at the end, otherwise they are worthless. However, 3D printers can not produce objects of any size. This is why you keep an eye on the installation space of the printer. Often large items can not be printed in one piece, but only in parts, in order to put them together afterwards to the final object. This must already be defined in the template.
Correct file size: The most common format for 3D templates is STL (Standard Triangle Language). Behind this is the principle that the design is composed of triangles in a three-dimensional space. If these are too big, the template is too coarse. The result is that the surface of the printed object does not fall smoothly but unevenly. If the triangles are very small, the surface of the printed object will be very fine, but the STL file will also grow.
However, some 3D printers can not handle overly large STL templates. A file size to be processed is 100 MB. In many hobby 3D printers, the processing limit is even around 10 MB.
If you now convert the design into your STL file into your design program, set the tolerance value for the conversion process to 0.01 millimeters. This means that the designed shape of the object converted into triangles may differ only by this value. For higher tolerances, you risk triangles after printing. A 3D printer usually can not display lower tolerances. The file will be too large without the resolution quality.
