Additive Manufacturing 3D Printing an Additive Manufacturing technique
Additive Manufacturing 3D Printing technology, often described as additive manufacturing, focuses on the methods used to produce a 3D object, wherein the material layers are successively laid to construct a solid part under a computer-controlled programme.
Additive Manufacturing (AM) is really an evolving 3D printing technique that facilitates the design and rapid development of complicated materials with intrinsic microstructures. 3D printing development has allowed manufacturing firms to grow from concept design and 3DP to fast end consumer manufacturing. Additive manufacturing allows the parts to be crafted in a layer by layer manner, the contrast to traditional manufacturing techniques focused on machining, forging and subtractive processes in order to produce the finished product. AM uses computer-aided design tools to plan and monitor the nozzle and stage of a 3D printing device for virtual objects.
Is additive manufacturing the same as 3d printing?
Additive manufacturing, as the name suggests, adds polymers to build a component. People should not be bothered regarding the current word in this context since they already represent the same process, 3D printing and additive manufacturing can be interchanged.
3D printing is a method of creating a single thin layer of materials simultaneously at a time. In theory, it is additive, not subtractive process. 3D printing is the special development on a desktop printer of repeated objects.
What are the types of additive manufacturing?
Comprehension of the seven additive forms are:
- Binder jetting.
- Directed Energy Deposition.
- Powder Bed Fusion.
- Sheet Lamination.
- Material Extrusion.
- Material Jetting.
- Vat Photo Polymerization.
Applications of Additive Manufacturing 3D Printing:
Polymers are the most widely used components for additive manufacturing because of their flexibility and wide variety of mechanical and chemical properties. Additive manufacturing polymers comprise thermoplastics, elastomers, polymers, biopolymers and polymers mixed with biological materials, as well as thermoplastics. With the architectural design and choice of polymers, we get an improved materials, mechanical properties, porosity, and stability can be created. This creation of multi-functional 3D polymer-based printing materials for the manufacture of medicinal equipment, electronic devices and items that are applicable to aircraft.
History of 3D Printing:
3D printing is an additive manufacturing technique (AM), which enables the layer-by – layer creation of parts with complicated geometries. When an Engineer “Charles Hull” who brought the first printer to the market in 1986, and after that 3D printers became popular. The first stereolithography (SLA) technique was invented by Charles Hull for the quick creation and production of tiny plastic prototypes. Stereo lithography uses light to enable polymers inside a resin to build 3D, complex shapes (the reaction process is called as photo polymerization). The firm “3D Systems” commercialized this SLA system in 1987.
After this discovery, considerable endeavour has been made to manufacture a range of plastics in machines. A couple of the techniques currently available in the commercial market are Fusion Deposition Modelling (FDM) and Direct Ink Writing (DIW).
Additive manufacturing process steps
- Step 1 – 3D model creation.
- Step 2 – STL file creation.
- Step 3 – STL file transfer.
- Step 4 – Machine set up.
- Step 5 – Build.
- Step 6 – Part Removal.
- Step 7 – Post processing.
Why to use Industrial Additive Manufacturing as a technology of future production?
- Reduce assembly cost, boost space use
- Smart, inter – functional greatly decreases number of components and leverages space available, allowing more manageable physical demands and assembly costs.
- Less material used and less energy usage
- Lightweight structures in diverse industries are becoming increasingly desirable, as material use, costs, weight and energy consumption are also dramatically decreased by applications.
- Cost-efficient output of parts even in sequence
- Reduce the manufacturing and storage costs of new parts by locally sourcing parts on request
- Pace the production and prototyping of goods to reach the competitive lead
- Completely recreate items, without wax patterns or tools.
