Adoption of 3D printing has grown rapidly as it is the fastest, most affordable, and widely used method of prototype creation. Also known as additive manufacturing, 3D printing continues to gain popularity with an increasing number of firms investing in the industry. At Agile Manufacturing, we offer premium 3D printing services in Ottawa to both commercial and individual clients.
With the growth of technology and other relevant aspects, 3D printing has evolved since its inception. Today, there exists many different 3D printing processes, however, Fused Deposition Modeling (FDM) is one of the most common and widely used process due to its lower start-up and material costs and reliability.
Below, we will discuss FDM in detail which can help inform you about 3D printing services in Ottawa.
What is Fused Deposition Modeling?
Fused deposition modeling (FDM) 3D printers work by extruding thermoplastic filaments such as ABS or PC through a heated nozzle. The material is laid layer by layer on a build platform until the part is complete. All that is needed to start printing in FDM is a CAD file. With the use of a slicer software, the CAD file is converted to a format that can easily be understood by the FDM printer before the printing process begins.
FDM printing makes use of two building materials: the modelling material (ABS or PC to name a few) and the support material. The modeling material constitutes the finished object. The support material is used as a scaffolding to support the object being printed. This material is removed and disposed to reveal the final printed part.
Most common modeling materials in FDM are ABS, Nylon 11/12, PC, PC/ABS, PEEK/PEKK and TPU. Materials come in all types of colors. FDM printed parts print in production-grade material which make them ideal for functional prototypes and even end-use parts.
FDM parts are not always printed in solid. To reduce overall print time and to save material, voluminous parts can be filled with an internal, low density structure called ‘sparse infill’.
