Abstract

The present study investigates the effect of the concentration of flexible resin on the dimensional accuracy of mixtures product manufactured by 3D printing using SLA technology. Specimens were designed and according to the ASTM D412 standard. Ten variations of resin mixtures were examined. The concentrations of the flexible resins were varied from 10% to 100%. Measurements of accuracy dimension were conducted on the fabricated specimens, and the average deviation was used to estimate the dimensional accuracy. The study reveals the least deviation in dimensions in the 10% flexible resin containing mixture and the highest in the 60% flexible resin containing mixture. The results explain the fabrication tendency of flexible resins in dimensional accuracy for 3D printing.

Abstract

Over the years, technologies of 3D printing have enhanced the opportunity to ease the production of complex geometries. In particular, it further implies that the flexibility of materials is of a great importance. Therefore, the works covering studies of applicability on novel materials in rapid prototyping contribute to the development of additive manufacturing. The present work experimentally investigates a mechanical property, namely tensile strength, of 3D printing materials on the basis of the concentration of flexible-standard resins. Tensile strengths were obtained by a series of tensile tests. Here, the result reveals that the tensile strength monotonously decreases as the increase of the concentration of flexible resin’s concentration. Moreover, an ANOVA analysis strongly implies a consistent relationship between the tensile strength and the material’s mixture.
