“…This demonstrates the flexibility of the spring-assisted mechanism in adjusting parameters to vary the separation force and separation time. ANOVA was performed to obtain the relationship and significance of each parameter considered in this study, following the practices of Zamheri et al [34] and Putra et al [35]. Comparing the optimal parameters for minimizing the spring-assisted mechanism's separation force and separation time, both required the longest axle base.…”

Resin three-dimensional (3D) printing is potentially attractive for the rapid fabrication of micropatterning tools such as stamps, molds, masks, or substrates. Although the horizontal surface finish of a resin 3D printed part is generally considered to be very smooth, it is strongly influenced by the microscale interaction of the printer light source with the photopolymerizable resin. This study demonstrates how a glossy surface can be created on an elastic 3D printed component by extreme overexposure of the cap layer and how this can be analyzed. The average roughness (R a ) values of the surface in the X and Y directions could be reduced by a factor of 4.5 (X) to 5.0 (Y) from initially 0.182/0.343 to 0.041/0.069 μm (X/Y), and geometric accuracy was ensured by undersizing the features in the cap layer. The practical relevance of controlling the horizontal surface properties was demonstrated using a 3D printed stamp to transfer a micropattern of light-emitting quantum dots. The insights gained will be useful in the fabrication of 3D-printed tools for creating high-resolution patterns from quantum dots, semiconductors, and organometallic materials.

In the field of additive layer manufacturing, constrained-surface digital light processing has attracted considerable attention due to its high precision and low material loss. During the process of separating the cured layer from the resin tank, the high separation force generated by the pulling-up mechanism increases the printing failure rate and reduces the life cycle of the resin tank. Although changing the separation mechanism can significantly reduce the separation force, this often has the tradeoff of high equipment costs. This study comprehensively evaluated the performance of a low-cost spring-assisted mechanism for the separation process. The Taguchi method was used to confirm the variability of the spring-assisted mechanism and obtain the parameters that minimize the separation force and time. The spring-assisted mechanism was then applied to printing different geometric shapes and areas, and the results demonstrated better manufacturing stability than the pulling-up or tilting mechanism. A linear regression equation was established to predict the separation force of specific geometric shapes and areas to greatly reduce the calculation costs and time.
