Printer forming cylinder and using method thereof

Abstract

The invention discloses a printer forming cylinder and a using method thereof. The printer forming cylinder comprises a cylinder body, a hollow piston, a powder leakage ring, powder recycling boxes and a center base plate; the hollow piston is slidably connected with the cylinder body in a sealed mode; the powder leakage ring is installed in the hollow piston and can be rotated by a first preset angle every time, the second preset number of holes are uniformly distributed in the powder leakage ring, the second preset number of slideways are uniformly distributed in the powder leakage ring, andpowder falling onto the slideways can slide into the holes through the slideways; the second preset number of powder recycling box groups are arranged, each powder recycling box group comprises the third preset number of powder recycling boxes, the powder recycling boxes are uniformly distributed under the powder leakage ring, and the size of openings of the powder recycling boxes is not smallerthan that of the holes; and the center base plate is installed in the hollow piston and can enable redundant powder laid on the center base plate to be thrown onto the powder leakage ring through centrifugal force, and the effect that different kinds of powder are thrown into the different powder recycling boxes is achieved.

Description

Technical field [0001] The invention relates to the technical field of printing equipment, in particular to a printer forming cylinder and a method of use thereof. Background technique [0002] Selective laser melting (SLM) is an additive manufacturing method that uses laser sintering. Its principle is: making spherical powders of metals or non-metals and paving them, using a laser beam controlled by a data file to pave The powder is scanned and sintered. Repeat the "powder-sintering" step until you get a three-dimensional solid. It is characterized by short production cycle, low development cost, and unlimited shapes of molded parts. [0003] With the continuous development of 3D printing technology, selective laser melting (SLM) technology has also been greatly improved. However, most of them can only print a single uniform material. In fact, most parts and products are composed of multiple or non-uniform materials. Therefore, SLM3D printers that can print multiple materials a...

AI Technical Summary

Problems solved by technology

However, most of them can only print a single uniform material at present, but in fact most parts and products are composed of multiple or non-uniform materials. Therefore, SLM3D printers that can simultaneously print multiple materials have become an urgent need in the field of rapid prototyping manufacturing

[0004] At present, when printing multiple materials at the same time, it is impossible to classify and recycle the redundant different powders after each layer is sintered, resulting in mixed pollution between different powders, resulting in powder waste and increasing costs
