本节主要介绍两类基于该原理的陶瓷3D打印技术，即采用喷口加热的熔融沉积制造（Fused Deposition Modelling-FDM）和添加溶剂的浆料直写（Direct Ink Writing-DIW）技术。

Feb 27, 2024 · We offer the possibility of implementing a lab-made extruder for direct ink writing (DIW) into a conventional fused deposition modelling (FDM) 3D printer.

挤出式打印 是最常用的一类生物3D打印方式。 它是喷墨式打印的升级版本，可以打印粘度更高的生物材料，如水凝胶等。 根据其打印材料性质的不同，可细分为 FDM（Fused deposition modelling,熔融沉积）和 DIW（direct ink writing，生物墨水直写）两类。 前者主要用于热熔性高分子材料（PLA，PCL等）的打印，基本原理是采用加热模块将高分子材料熔融变软（200°左右），然后用机械结构将高分子材料拉丝挤出，高温的丝状材料遇到较冷的平台后凝固成型。 …

The main difference between FDM and DIW is that in FDM polymeric filaments must be melted during extrusion, while DIW systems rely purely on pastes with very specific rheology that are stored in a syringe cartridge.

Schematics of five different 3D printing techniques, including material jetting (MJ), direct ink writing (DIW), fused deposition modeling (FDM), stereolithography (SLA), and digital light processing (DLP), and their applications in single material and multi-material ceramic 3D …

The DIW printer allows the seamless print of a wide range of materials, including the precise fabrication of single-component silicone structures, the expert handling of ceramic pastes, and the effortless creation of objects from photo-curable materials.

The two most interesting processes are the Fused Deposition Modeling (FDM) and the Direct ink Write (DiW). The FDM is the most known method. A thermoplastic polymer, such as Polylactic Acid (PLA), is fused then deposed on the plate.

Jun 1, 2020 · Using FDM, self-folding metamaterials have been successfully printed; and while using UV-supported DIW, the printing of highly stretchable self-healing shape memory elastomers have also been achieved for the biomedical industry [114, 115]; highlighting the possibilities with ME3DP techniques for future multifunctional products.

May 2, 2021 · Among them, direct ink writing (DIW) enables the extrusion of viscous inks instead of solid filaments, usually melted in an FDM 3D printer. The DIW technology allows the 3D printing of various inks such as hydrogels for biomedical applications, [8, 9] ceramic materials, ionogels, and nanocomposites for sensors and energy devices.

May 29, 2024 · A team has integrated a single build head with FDM, direct ink writing (DIW) and freeform laser induction (FLI). This lets them extrude and functionalize a wide range of materials and...
