... powder bed fusion (LPBF). This study aimed to examine the correlation between down-skin surface area and the manufacturability of lattice structures fabricated using LPBF. Image processing algorithms were used to analyze down-skin surface areas of seven unique lattice designs and to devise quantitative...

...Yancheng Zhang; Charles-André Gandin; Michel Bellet A super-layer deposition method is developed for 3D macroscopic finite element modeling of heat transfer at part scale during the powder bed fusion (PBF) process. The proposed super-layer strategy consists of the deposition of batches of several...

... considerations. Table 3 categorizes various AM processes based on omnidirectionality. The use of F-theta lenses, layer irradiations, and flying optics are suitable for achieving omnidirectionality in Vat photopolymerization. Powder bed fusion (PBF), which is similar to Vat photopolymerization in the context...

...Yuan-Hui Chueh; Xiaoji Zhang; Chao Wei; Zhe Sun; Lin Li In this paper, the printing of 3D functionally graded polymer/metal, polymer/ceramic composite components via an ultrasonic vibration-assisted laser-based multiple material powder bed fusion (PBF) is reported. Components consisted of various...

...Tesfaye Moges; Gaurav Ameta; Paul Witherell This paper presents a comprehensive review on the sources of model inaccuracy and parameter uncertainty in metal laser powder bed fusion (L-PBF) process. Metal additive manufacturing (AM) involves multiple physical phenomena and parameters...
