The rapid solidification during above-mentioned AM processes can restrict the compositional segregation and the formation of the brittle intermetallics in the built parts, contributing to the strengthening effect through grain refinement [62], [76], [77], presenting great potentials for fabricating HEAs, which has gained increasing interest in the
Additive manufacturing (AM), also known as 3D printing, is a transformative approach to industrial production that enables the creation of lighter, stronger parts and systems. As its name implies, additive manufacturing adds material to create an object. Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial
The report also presents the bigger picture, including all steps involved in the full manufacturing process. Successful metal AM requires 3D CAD modeling, creating 3D printable files, repairing files to close holes and clarify facet layouts, the layered-manufacturing process and a variety of possible post-build steps.
Additive manufacturing (AM) also known by other names as well such as three-dimensional (3D) printing, layered manufacturing (LM), rapid prototyping (RP), and solid freeform fabrication (SFF) is a novel method of manufacturing that builds three-dimensional parts layer upon layer using computer-aided designing (CAD) data.
AM processes can be divided into the two sub-steps: generating a layer and joining a layer with the previous layer. This procedure means that the procedure corresponds strictly to a 2½D procedure (Gebhardt 2016). 2.1 Classification of additive manufacturing
3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by

Abstract. The Additive Manufacturing (AM) process is a computer-controlled process that uses CAD representations to build physical parts layer by layer. Almost all computer-aided design (CAD) packages allow the creation of stereolithography (STL) files, which are translated into machine commands to drive the AM process.
Step 2: Design Your Part. When spare parts are modified for AM production, the geometry of the finished part must be made to fit seamlessly into an existing assembly. In these cases, the real design work isn''t making significant changes to the shape of the part but performing minor design modifications to optimize for additive production
A foundation in math, at least through trigonometry. Familiarity with CAD software; topology optimization, design for additive manufacturing ( DFAM) and more can build on this foundation. Experience with other forms of manufacturing such as CNC milling, injection molding, welding. An understanding of materials science, whether in
What is additive manufacturing. Additive manufacturing, also known as 3D printing, is a process used to create a physical (or 3D) object by layering materials one by one based on a digital model. Unlike subtractive manufacturing that creates its final product by cutting away from a block of material, additive manufacturing adds parts to form
The whole additive manufacturing process can be explained in 9 different steps, five of which involve a succession of information conversions through different software. Let''s look in detail at each stage of the process:

Using computer aided design (CAD) or 3D object scanners, additive manufacturing allows for the creation of objects with precise geometric shapes. These are built layer by layer, as with a 3D printing process, which is in contrast to traditional manufacturing that often requires machining or other techniques to remove surplus material.
By optimizing the design to put material just along the direction of force vectors, unnecessary wasted material (that would be cut away with subtractive processes) would not be needed in the first place.
