Laser adjustable device applied to cylinder making and used for 3D printing

Abstract

The invention discloses a laser adjustable device applied to cylinder making and used for 3D printing. The laser adjustable device applied to cylinder making and used for 3D printing comprises a sliding rod, a first slider, a laser shooting head and an adjusting device; the sliding rod is arranged on the inner wall of a 3D printer in a sliding manner; the first slider is arranged on the sliding rod in a sliding manner; the adjusting device comprises a rotating motor, a disk and a micro hydraulic cylinder; the rotating motor is fixedly arranged at the lower end of the first slider; the axis position of the disk is connected with an output shaft of the rotating motor; the disk is provided with a slide groove; a second slider and the micro hydraulic cylinder are arranged in the slide groove;a telescopic rod of the hydraulic cylinder is connected with the second slider; and the laser shooting head is installed at the lower end of the second slider. By means of the laser adjustable deviceapplied to cylinder making and used for 3D printing, the laser shooting head on the 3D printer can achieve the arc-shaped movement, the roughness phenomenon of the arc position in the printing processis avoided, and a product can be more exquisite and aesthetic.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a laser adjustable device for 3D printing used to make cylinders. Background technique [0002] At present, 3D printers are gradually appearing in people's field of vision, and selective laser sintering (SLS) 3D printers, as an important means of industrial processing, are increasingly playing a role that cannot be ignored. This technology uses solid powder as raw material to directly convert CAD models into entities. According to factors such as material properties, part structure and process requirements, the powder spreading device of SLS3D printing equipment evenly spreads a thin layer of powder on the working platform for sintering of a layer of cross-sectional shape. The thickness, density and uniformity of the powder layer etc. directly affect the sintering quality.

Problems solved by technology

[0003] The resolution of the 3D printer is enough for most applications (it may be rough on the curved surface, like the jagged image), and to obtain higher resolution items can be obtained by the following methods: first use the current 3D printer Make a slightly larger object, and then a little surface grinding can get a smooth "high-resolution" object, but when you want to print a fine object, the curved surface will be as rough as sawtooth, which is difficult to accept. If you take Grinding in the later stage is laborious and laborious, and it is easy to cause damage to the object
