The maximum dimensions of the model are determined by the size of the camera of a printer that is used for printing.
Make sure that your model fits the specified dimensions. You can reduce the overall size of the model by scaling it, removing protruding parts or making a collapsible model.
The minimum dimensions of the model are determined by printing quality of a printer.
Make sure that your model fits the specified dimensions. You can increase the overall size of the model by changing the scale, combining or increasing the fragements or try to use material with a lower minimum size.
Thin walls are often broken when cleaning the product of excess powder. For successful printing of your model, make sure that the wall is thicker than the minimum requirement.
If the model contains hollow spaces they will be filled with powder while printing. To clean the product of excess material it is necessary to provide holes. In the case of large cavities, it is recommended to make several holes in the construction.
If the model contains several functional parts, it is necessary to provide sufficient distance between them, otherwise, the powder may fill the gaps, or in the process of printing parts will be merged.
Models are made from metal well-granulated powder. The technology of Direct metal laser sintering (DMLS) is used for printing. The layer thickness is 20-100 microns. Printing is carried out as follows: the fine metal powder is spread thinly on a platform which lowers vertically. Printing of the product is produced by laser melting the powder layer by layer, thus forming a finished object. The procedure takes place in a closed chamber. As the printing process is finished the model cools down, cleaned of excess material and is transmitted to the post-processing.
