A 3D printer, unlike other printers, transforms digital models into a real, physical 3D object. It is an additive manufacturing solution that works by adding a layer of a material at a time. The traditional manufacturing process is a subtractive process where there is wastage of raw materials which will be reused over and over again. For example, while making car components, plastic sheets are cut, shaped and moulded into the specific body parts. There will be leftover materials that will be melted into plates before they find different purposes.
We are the leading plastic manufacturing companies in India providing top-class 3D printing services for various purposes. Manufacturing using a 3D printer is an additive process where layers and layers are added until the object is finalized. There are many facets to additive technology which differ mainly in the way layers are added to make objects.
The most commonly used technology is Fused Deposition Modelling or FDM. FDM 3D printing is also called Fused Filament Fabrication or FFF. The process makes use of metal wire or plastic filament which unwound to supply material through a nozzle. We can turn the flow on and off. The nozzle is controlled by a numerical mechanism and is heated to melt material which can be moved in both vertical and horizontal directions. We opt for FFF technology to produce high-quality precision parts for our customers in India.
It is important to know the different printing techniques to understand their unique capabilities to achieve the result you want. The FDM 3D printing technology makes use of 2 types of printing systems, namely, Delta and Cartesian. The main difference between the two is the method of moving. Cartesian 3D printers make use of Cartesian coordinate systems of X and Y axes. The print head travels linearly on both X and Y axes. Cartesian printers move from the front to back, up and down, and left to right. It moves from A to B by moving one axis at a time. These printers have a moving bed that moves towards the nozzle. Cartesian printers are easy to handle, learn, and are cheaper. It creates great horizontal prints.
Delta 3D printers also use a Cartesian coordinate system but do not use linear motion. They use three arms consisting of a parallelogram that moves from one X or Y point to another by changing the angles of the parallelogram. The arms of the printer hang from a fixed platform. Delta printers provide high-speed printing capabilities with accuracy. They excel in printing at vertical height. The machine and the moving arms are light and easy to handle. The printer is easy to maintain and also can be upgraded quickly. Due to the construction of arms, 3D printers are much taller and occupy more space.
3D printing is a great way to produce low-cost prototyping which is an important aspect of the design and production cycle. A prototype using 3D printers will be ready within 1 to 5 days based on the size of the prototype. In traditional manufacturing, it will take months. 3D printing can make use of a wide range of materials. Regular plastic materials like ABS and PLA and many others can be used. 3D printing can make a difference in terms of duration. CAD can be used to create complex models and then transformed into a 3D model using the 3D printer.
3D printing can be used when you want easy customization. Traditional processes can be used to manufacture Identical products in large volumes while 3D printing is used for custom-made products. Complex shapes and patterns can be quickly accommodated in a 3D printer. We can also easily change and improve the design as and when we want at no extra cost. Another main benefit of 3D printing is it creates products in a single step with no interaction from operators with absolutely no errors. Another advantage is that no one can claim your innovation. This makes you stay ahead of the competition confidently.
