Interfacial Regulation for 3D Printing based on Slice‐Based Photopolymerization

Abstract

3D printing, also known as additive manufacturing, can turn computer‐aided designs into delicate structures directly and on demand by eliminating expensive molds, dies, or lithographic masks. Among the various technical forms, light‐based 3D printing mainly involved the control of polymer‐based matter fabrication and realized a field of manufacturing with high tunability of printing format, speed, and precision. Emerging slice‐ and light‐based 3D‐printing methods have prosperously advanced in recent years but still present challenges to the versatility of printing continuity, printing process, and printing details control. Herein, the field of slice‐ and light‐based 3D printing is discussed and summarized from the view of interfacial regulation strategies to improve the printing continuity, printing process control, and the character of printed results, and several potential strategies to construct complex 3D structures of distinct characteristics with extra external fields, which are favorable for the further improvement and development of 3D printing, are proposed.

Inkjet Printing of Long-Range Ordering Two-Dimensional Magnetic Ti0.8Co0.2O2 Film

“…It, therefore, has a broad application prospect in the fields of flexible electronics, wearable devices, smart packaging, and sensors [2]. These include, among others, inkjet printing [3,4], 3D printing [5], screen printing [6], spin coating [7], spraying [8], and other printing processes [9]. Inkjet printing enables fast, flexible patterning without the need for complex processes.…”

Defects in 3D Printing and Strategies to Enhance Quality of FFF Additive Manufacturing. A Review

“…The printing material is dispensed or secured in such a manner that it forms a part profile at a certain height, which corresponds to the digital model [18,19]. The advent of numerous AM methods now enables the creation of products from diverse materials such as thermoplastics [20,21], photopolymer resins [22][23][24][25][26][27][28][29], composites [30][31][32][33][34][35], metals [36][37][38][39][40][41], ceramics [42][43][44][45], and soft matter [46][47][48][49]. Fused Filament Fabrication (FFF) has emerged as one of the most popular 3D printing methods, attributed to the low initial cost of personal 3D printers and the availability of a wide array of thermoplastic printing materials.…”
