Vibration-absorption and refrigeration working box of 3D (Three Dimensional) printing machine

Abstract

The invention discloses a vibration-absorption and refrigeration working box of a 3D (Three Dimensional) printing machine. The vibration-absorption and refrigeration working box comprises an outer boxbody and an inner box body, wherein the outer box body sleeves the inner box body; the working box is divided into two layers of box bodies; a box body part is provided with a retractable rod; the retractable rod is used for stabilizing the inner box body and certain floating of moving up and down can be regulated and controlled; a spring has the effect of regulating and controlling the up-down floating; furthermore, flowable ice water is filled in an interlayer of the box body and a buffering layer is formed so that the transmission of vibration between the box bodies is stopped; the influences, caused by vibration of a motor, on a printing effect are reduced at maximum. Furthermore, cold air cooled above the ice water is blown onto a hoisting platform through an air blower and the temperature of the part of air is lower than common air temperature, so that the cooling effect is better.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing of casting and forging molds, in particular to a shock-absorbing refrigeration work box for a 3D printer. Background technique [0002] 3D printing, also known as additive manufacturing, is a collective term for a series of processes. A brief overview of its principle is to transform the digital 3D model file into a 3D object layer by layer through layer-by-layer superposition. At present, the main additive manufacturing processes include: 3DP technology, selective laser sintering (SLS), stereolithography (SLA), fused deposition modeling (FDM), etc. The principle of FDM fused deposition modeling technology is to melt heat-sensitive materials into a liquid state, deposit them on a designed cross-sectional path through a computer-controlled extrusion nozzle, and rapidly form them after rapid cooling. When the section of a layer is formed, the nozzle moves along the Z axis to the...

Problems solved by technology

However, the rotation of the cooling fan will easily cause the extrusion nozzle to vibrate, resulting in ripples on the surface of the printed model, which will affect the printing accuracy. At the same time, the fan’s air supply range is too large, which will also cause the temperature of the extrusion nozzle to cool down and cause the material to be extruded unevenly. will have an adverse effect on the final printing effect.
