Abstract
Real-Time Monitoring Technology of Plaster-Based Three-Dimensional Printing System for Quality Determination of Model Structure
Highlights
Three-dimensional printing (3DP) employs additive manufacturing (AM) technology to fabricate an object by building layer upon layer successively
The smoother contour of gypsum can be observed owing to the lower reflectance after the bassanite absorbed the water, as shown in Fig. 8, and these results were similar to those of Harrison.[17] the UV-light-emitting diode (LED) light will be employed as the light source in the real-time monitoring system in the 3DPTM process
By using the UV-LED as the light source of the real-time monitoring system for the 3DPTM process that modeled from bassanite and adhesive to gypsum, images with contrast substantially higher than those using light of other wavelengths can be obtained
Summary
Three-dimensional printing (3DP) employs additive manufacturing (AM) technology to fabricate an object by building layer upon layer successively. Several types of CPCs were investigated to increase the modeling strength and setting time by adjusting the composition of CPCs. For example, calcium sulphate cement (CSC) is another bone-substitute material, which can be blended together with CPC in different proportions. Guo et al[12] investigated a new type of composite bone cement by mixing CSC and CPC, and the setting time of the model was 5–20 min. The results showed that the shortest setting time of about 12 min can be obtained by adding distilled water to the cements, but this sample has the weakest compression strength. The highest compression strength, 5.9 ± 1.5 MPa, can be obtained when the adhesive is glucose, but the setting time is 74 min
