“…0 E C 0 signifies the critical energy for the photopolymerization process and 0 D P 0 represents the penetration depth at which 1=e of exposure energy (E) is reached during the curing process. It can be shown in Equation (3), that the radiation intensity (I) of a UV beam is directly proportional to time (t c ) when the UV beam is constantly illuminated from the source.…”

“…AM allows for the creation of complex geometries with high accuracy and resolution, 1 which is essential for producing polymer composites with desired properties. The addition of reinforcing fillers to polymers can enhance their mechanical, thermal, and electrical properties, making them suitable for aerospace, biomedical, and electrical industries 2–4 . However, the successful implementation of polymer composites in AM requires careful consideration of the materials' compatibility, process parameters, and post‐processing treatments.…”

Short or nanofillers‐reinforced composites increase the thermo‐mechanical characteristics of additive manufacturing (AM) base materials. Effective outputs were regulated via parametric optimisation and custom production. One of the most used AM method, Vat photopolymerization (VPP), creates complex and geometrically precise photopolymer parts. This study prepares photopolymer composite (PPC) samples with 2.0, 4.0, 6.0, and 8.0 volume percentages of short glass fiber (SGF) using an inter‐stage stirring method in DLP‐based VPP process. An adequate curing time and formable layer thickness were evaluated for the printability performance of SGF‐photopolymer composite. The 4.0% PPC‐sample showed a 20% higher compressive yield strength than pure photopolymer and other volume fractions. The consequences of increased strength values were assessed by the effect of stirring method and the fractography analysis of PPC specimen. The investigation additionally encompassed numerical simulations that employed an innovative technique for constructing and simulating three‐dimensional representative volume elements (RVEs). The RVEs were designed to replicate the experimental outcomes by randomly situating and orienting fillers within the matrix. The study employs the calibrated Three Network (TN) viscoplastic constitutive material model as the matrix property, and the simulation results demonstrate a margin of error of 5%–10% when compared to the experimental findings.Highlights Layer‐wise availability of SGFs through inter‐stage stirring method The exposure time and layer thickness were determined by Jacob's working curve Concept of RVE is used to combine individual SGF layers into a single layer SEM showed that increasing SGF layer resists cracking better than neat matrix Experimental data and numerical simulations are in good agreement

Additive manufacturing techniques have by far been utilised to make 3D passive components (i.e. resistors, inductors, and capacitors), circuit boards and packages of power electronic devices. This paper provides an overview of automatic assembling technologies and additive manufacturing applications in power converters, as well as the advantages and limitations of each additive manufacturing process in this area. It shows that direct metal laser sintering offers advantages for manufacturing inductors with the conductivity of 68% of the International Annealed Copper Standard (IACS) and magnetic cores with the permeability greater than 10000 at 50 Hz. The additive electronics from Nano Dimension show great promise for fabricating power converter PCBs with the conductivity from 25% to 50% IACS. Additive manufacturing in thermal management and packaging has been extensively studied and will spark more changes in these fields. Besides, the potential of the combination of automated and additive manufacturing in power electronic systems has also been discussed, which sets the basis for future development of advanced manufacturing of power electronics.

“…However, their focus was on the application of a single method of AM, powder bed fusion. Muthu et al [15] reviewed similar technologies and AM methods, but there have been recent advancements in areas such as composite manufacturing, packaging and TM applications. Lastly, Espera Jr. et al [16] provides a detailed review on the application of various AM for electronics, including passive component and printed circuit board manufacturing.…”

To meet the upcoming challenges of higher power density and higher efficiency for power electronics, a system level approach to the design of power electronic devices must be carried out. Higher system integration and packaging will allow for more compact designs but will also result in challenges for component manufacturing and thermal management. Additive manufacturing can potentially mitigate some of these challenges due to the design flexibility and intricate features that additive manufacturing methods can provide. This paper presents an overview of the additive manufacturing technologies currently in practice at the academic and industry level. A detailed review is presented of current applications of additive methods for the production of power electronic components, advanced heat exchanger designs and integrated power electronic systems.
