Fused Deposition Modeling or FDM is a layer additive manufacturing process that produces three-dimensional products used extensively in prototyping and also to produce end parts. Production grade thermoplastics materials are used for this technique, which is laid down in successive layers to produce the end product. The technique is technology-assisted with computer-aided software guiding the whole process. The FDM technology is a widely used 3D prototyping process that is ideal for concept models, manufacturing aids, functional prototypes as well as manufacturing low-end parts. The accurate features and tremendous strength to weight ratio makes the FDM process a much sought after technique across various industries in India. Learn more about this rapid prototyping service in the following section.
FDM prototyping service, use layers of liquefied thermoplastics expelled through the extrusion nozzle. The whole process is program assisted that begins with the ‘slicing’ of 3D data into layers. This data then guides the printer that constructs the desired part layer by layer on a platform. The thin thread-like molten thermoplastic and support materials create the cross-section of the final product. The dual heated nozzle then extrudes the molten materials into layers. The extrusion nozzles move in the x-y plane to build the layers with the building platform moving down with each added layer. After the whole process, the FDM part is then removed from the build platform, and the supporting material is cleared from the raw FDM. The raw FDM consists of visible layer lines, which are then exposed to finishing processes like smoothening, sanding, or cosmetic painting for a finished look. The production-grade plastics used in the FDM production ensures durability and functionality that makes them a suitable inclusion in several industries. Here are the top industries in India that extensively use 3D printed injection molds for FDM materials.
The FDM rapid prototyping service is an excellent initiative that is not only affordable but also ensures durability and heat resistance properties. This is the reason why FDM parts are extensively used across the aviation and medical industries in India. Understand how FDM is used in the following industries.
Bio-printing is used to produce tissues and organs that imitate natural tissue or organ character, to aid in the research of drugs and pills. The emerging FDM technology has made it possible to print cells or extracellular matrices by depositing 3D gel in layers to recreate the tissue and organ. The co-culture ability, high-throughput capability and low-risk contamination are beneficial in a variety of researches and testing.
Rapid prototyping services are fast gaining prominence due to their many advantages. The extensive customer base that was once utilizing conventional methods are convinced of the FDM prototyping and are fast shifting their preference to 3D printing.
