Abstract

The invention discloses a 3D printer control system with temperature-compensable shower nozzles, comprising an upper layer control module comprising an ARM chip, a man-machine interaction module and a SD card slot which are connected to the ARM chip respectively; an RS232 serial communication interface is arranged on the man-machine interaction module; a lower layer control module comprising a FPGA chip and an I / O control module connected to the FPGA chip; the ARM chip and the FPGA chip are communicated through FSMC bus; the ARM chip is connected to an ambient temperature sensor, and the FPGA chip is connected to a first shower nozzle heating module and a second shower nozzle heating module respectively. In the 3D printer control system disclosed by the invention and based on ARM-FPGA structure, the temperature compensation of the shower nozzles is performed according to the monitoring result of environment temperature change, so that the quality of 3D printed products is guaranteed and improved during the environment temperature change.

Description

technical field [0001] The invention relates to the field of intelligent control of 3D printers, in particular to a 3D printer control system with a temperature-compensable nozzle. Background technique [0002] 3D printing technology, also known as rapid prototyping technology and additive manufacturing technology, refers to the precise 3D accumulation of materials under the control of a computer, according to the computer-aided design (CAD) model or computer tomography (CT) data of the object. The new digital molding technology for manufacturing 3D objects with arbitrary complex shapes has the advantages of short production cycle and low cost. Currently, 3D printing technologies mainly include stereolithography (SLA), selective laser sintering (SLS), and fused deposition modeling (FDM). [0003] The control of the 3D printer can store the slice data of the 3D object in the memory of the motion control card in the form of a G code file. When processing, select the target mo...
