Abstract：Aiming at solving the problem of low machining accuracy in domestically- developed three dimension printers （3DP），experimental study on a new 3DP control system was carried out. The control system was composed of hardware system and softwaresystem. The hardware system was established through motion control of motor and temperature control. PID arithmetic applied in DSP wasrealized in software system. Control principle was set up through PID control and fuzzy control. Model of control system was set up and
simulated through Matlab，hardware platform of 3DP control system was set up through DSP. The experimental results show that themachinability of new 3DP is significantly improved.
Key words：three dimension printers（3DP）；control system；DSP
