To build up integral SL system, a control system of vertical moving stage in the Integral SL system is established. The control system consists of small power stepper motor, movement control cards, driver of stepper motor, precision ball screw, linear guide. The motion accuracy of vertical moving stage in integral SL is an important factor which influences the building accuracy of the SL system. To...
To resolve the problem that thickness of resin layer increases with the object height during building process in piston recoating system, experimental investigations were performed to establish the model describing the relationship of recoating layer thickness with object height and blade speed by using response surfaces methodology. According to the model, a novel recoating process with dynamically...
The dimension accuracy in scanning plane of high-resolution stereolithography (SL) system with building parameters (laser beam scanning speed (factor A), cured line width compensation (factor B), hatch spacing (factor C) and the coefficient of resin's shrinkage compensation (CRSC, factor D)) were investigated in this study. A L27orthogonal array and signal-to-noise (S/N) were employed to analyze the...
