The term 3D printing encompasses several manufacturing technologies that build parts layer-by-layer. Each vary in the way they form plastic and metal parts and
After casting, the mold is broken apart and the final metal component is removed. 9. Direct Metal Laser Sintering (DMLS) and Selective Laser Melting (SLM) are 3D printing technologies that use Metal Powder Bed Fusion, the process where a heat source is utilized to fuse metal particles one layer at a time.

Key Laboratory of 3D Printing Process and Equipment of Zhejiang Province, College of Mechanical Engineering, Zhejiang University, Hangzhou, 310027 China. This work provides a comprehensive classification of smart structures and a detailed review of the functional materials and 3D-printing methods used for
Noting the difference in material use and factual characteristics, members of international trade community can now use HTSUS 8477.80.00 as a starting point of classification inquiry for 3-D printers that use thermoplastic powder, and HTSUS 8479.89.98 for 3-D printers that use metal powder, backed by the opinion of the court.
Although media likes to use the term "3D Printing" as a synonym for all Additive Manufacturing processes, there are actually lots of individual processes which vary in their method of layer manufacturing. Individual processes will differ depending on the material and machine technology used. Hence, in 2010, the American Society for Testing
Concrete, specifically, is one of them. In fact, the concrete 3D printing market is projected to be valued at $56.4 million by 2021, growth that''s largely spurred by the amount of new, innovative projects that are being planned in construction. 3D printing in concrete doesn''t appear just to be a grassroots movement, either.

Materials'' classification used in 3D printing process. 3D printing materials are those that can be used to produce desired goods using 3D printing technology [1]. 3D printing, like another manufacturing process, needs better materials characteristics that meet consistent standards to produce consistently greater-quality
The key feature of this classification is to reinstate strategies other than the sole extrusion step into large-scale 3D-printing of concrete. In 1997, Joseph Pegna famously stated the concept of "solid free-form construction", on which current approaches are
The introduction of 3D printing technology into the fabrication of smart structures has led to remarkable achievements. First, it provides an economical and effective method to fabricate complex smart structures, such as the 3D interpenetrating internal vascular networks mentioned earlier, [] vascular scaffolds, [] and curvature
In real terms, however, the origins of 3D printing can be traced back to 1986, when the first patent was issued for stereolithography apparatus (SLA). This patent belonged to one Charles (Chuck
An overview of 4D printing as a fascinating tool for designing advanced smart materials is provided, and the recent progress in AI-empowered 3D and4D printing with open-loop and closed-loop methods, in particular regarding shape-morphing 4D-responsive materials, printing on moving targets, and surgical robots for in situ printing are discussed.
Dimensional accuracy and deformation of models. One of the most accurate 3D printing technologies is MJP and PolyJet (MJT processes). SLA or MJF technologies also have high accuracy. MJT systems have a very high dimensional accuracy of ±0.1–0.2% with a typical lower limit of ±0.02–0.1 mm.

3D printing processes. Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
1. Design. 3D printers create parts from three-dimensional models, the mathematical representations of any three-dimensional surface created using computer-aided design (CAD) software or developed from 3D scan data. The design is then exported as an STL or OBJ file readable by print preparation software.
This paper presents the overview of the types of 3D printing technologies, the application of 3D printing technology and lastly, the materials used for 3D printing technology in manufacturing industry. Keywords: Additive manufacuting, 3D Printing, manufacturing industy 1.
Abstract. Purpose – This study aims to identify and classify the available types of 3D printing services, with the scope of determining the potential implications that such services could have
Era of 3D printing started in the late 20s and SL is the earliest 3D printing process ever introduced in the market and the first ever 3D printers set in motion were stereolithographic/ SL machines that were used to manufacture 3D models, 3D prototypes, 3D parts and patterns. Classification of materials used in various 3D printing
XRμCT which used x-rays for 3D scanning the as built part is now a widely-used technique for inspecting the AM parts, providing precise dimensional measurements. With AM, which enables complex

Concrete Printing [2–4] rely on pumping and extruding cement-based paste to create 2.5 D structures that are to be included in a larger building system. More recently, some of the co-authors of the paper have developed a novel concrete printing process featuring six axis robot control that allow full 3D elements to be manufactured without
Key Takeaways. Additive manufacturing: 3D printing builds parts from scratch by depositing material layer-by-layer, unlike traditional methods that remove material from larger blocks. FDM and resin printers: The two main types of 3D printers for hobbyists are FDM, which use plastic filaments, and resin, which use liquid resins cured by light.
