Also in 3D printing the printing material goes into the money. How you can lower the costs of filament, the tip tells you.
Printing is always costly. If, in classic printing, there are essentially additional costs for toner cartridges and ink cartridges, the filament rolls go into money in plastic 3D printing. But there are some ways to reduce the follow-up costs.
Hollow place filled: It does not always need to have a filled through and through subject. Therefore, make sure that you can not construct the object hollow. In order to maintain stability, you define the walls somewhat more strongly. If it does not work without inner supports, reduce the filling. Then you get inside a honeycomb design that gives support, but less material is needed than a complete filling. Especially for toys such as cubes or ornamental objects, which only serve for positioning, fillings of 20 percent are sufficient. Just try less. You set the degree of filling in the printer software, such as Slic3r, under “Print Settings” or “Print Settings” in percent. At 0 percent, the device prints the object hollow.
Props instead fill: As an alternative to filling you can support from outside in 3D printing hollow articles, to give them more stability during the printing process. These auxiliary structures are recommended for overhangs – such as handles of cups or angled arms or legs of figures. You simply remove it when the object is finished and cured. The advantage is that the supporting structure is only attached to the object on a point-by-point basis. Thus it requires less material than an entire filling. Disadvantage: Sometimes visible residues remain after the removal, which you have to remove with a file or sandpaper.
Sample Print in smaller form: In many cases you can not get around around your 3D printer Try until you have found about the ideal matching of temperature setting and filament. For these sample prints, you often do not need an original size. If the object is very large, a half-size print is often sufficient to assess whether the settings make sense.If you are satisfied with the result, print it in the final intended size. This saves not only material, but also printing time. The latter point can mean several hours in 3D printing.
Material change: Just as when printing on paper is also in 3D printing tends to original materials by the manufacturer. However, the chipping of cartridges has not yet been implemented across the board. Straight-forward machines such as those of the Ultimaker series have so far waived a limited material selection. You can take advantage of this. For often you will also find cheaper filament rolls than the one you get directly from the equipment manufacturer. However, make sure that the material thickness is correct. In addition, you are also exposed to a certain investment risk, because not every favorable filament holds in practice what it promises. If you do not want to change the manufacturer because the filament can be processed well with your printer, you can also save by removing a large amount of the proven plastic material at once.
