DEFINITION: Additive Manufacturing (AM) refers to a process by which digital 3D design data is used to build up a component in layers by depositing material. Additive Manufacturing (AM) is an appropriate name to describe the technologies that build 3D objects by adding.

The technical execution of AM processes is carried out by means of direct layer manufacturing process. The developed technologies for AM in the market can be categorized into five main processes. Each of these processes uses different methodologies in order to form a solid layer and fabricate the final part by connect-ing adjacent layers. All five ...
Polymerization results in very good surface quality and fine details. But it uses sup-port structures that need to be removed, and the parts mostly need to undergo the post-curing. The plastic material and its comparably low glass transition tempera-ture must be regarded as cons if tooling applications are needed.
Laser stereolithography machines (Viper SLA and iPro SLA Series) and polymer printers (ProJet Series) are developed by 3D Systems. Polymer Jetting machines (Eden- and Connex Series) are offered by Objet. Machines using DLP projectors (Perfactory Series) come from EnvsionTec.
Sintering processes can handle all materials that behave like thermoplastics which means they melt and solidify if heated and cooled down. Additionally, they must be available as powders. Sintering and melting enables making interior hollow Fig. 1.4 Selective laser sintering/melting process steps geometries. This opens up the possibility to make ho...
The process and the machines are easy to run even in an ofice environment. The process is mostly limited to plastics. The parts can be used within the product devel-opment process. The surface shows a texture due to the extruded strings that changes according to the orientation of the part within the build space. If used as master model for follow-...
Layer laminate processes can process all types of materials that can be processed thermally or mechanically. The big amount of waste compensates this favor at least partly and forces the designer to optimize the part’s shape and orientation. The advantage of LLM processes in general is fast manufacturing of massive parts.

Introduction to Additive Manufacturing. This chapter introduces the reader to the multiple domains of Additive Manufacturing (AM) technology, including its history, principles, proce-dural steps, and classifications.
Dec 7, 2017 · What is additive manufacturing? Additive manufacturing is the process of creating an object by building it one layer at a time. It is the opposite of subtractive manufacturing, in which an object is created by cutting away at a solid block of material until the final product is complete.

of making it more eficient and flexible. Today, in the early decades of the twenty-first century, additive manufacturing (AM) is the most advanced and cutt. ng-edge technique used in manufacturing. It entered the limelight as ‘3D printing’ and has flipped the tables in research and development with a paradigm shift, gradually ushe.

Nov 22, 2020 · Additive manufacturing (AM) is generally used (even if there are local designations in some countries) for directly making (manufacturing, production) of three-dimensional (3D) objects from digital data. The fabricated objects using AM represent prototypes or (final) products or parts of it.
