Effect of Printing Temperature on Mechanical Properties and Surface Quality of Photosensitive Resin Rapid Prototyping Parts

Abstract:

Abstract. The rapid prototypes of different printing temperature by Objet30 Stratasys Pro printer were found a certain difference in performance in the process of using the process.In order to studied the effect of printing temperature on the rapid prototyping of photosensitive resin, tensile and bending tests were carried out on the rapid prototyping parts at 12°C, 18°C, 21°C, 23°C, 25°C, 30°C,respectively,and the rigidity and surface roughness of rapid prototyping parts were measured.Research shows：the tensile strength increases with the increase of printing temperature , tensile elastic modulus fluctuates with the printing temperature , they all increases rapidly after 25°C;The bending strength increases proportional with the increase of printing temperature, and the bending modulus increases first and then tends to decrease with the increase of printing temperature;The hardness value increases slowly with the increase of printing temperature, and increases obviously after 20°C,the hardness value in the middle of the prototype parts is bigger than the edge parts；The surface roughness with increasing printing temperature, although it is floating up and down, but have little effect.
