Project Summary

Now a days, innovative technologies have brought science fiction  into reality by making our lives much more easy and comfortable. Recently, 3D printing helps in a far-reaching analog-to-digital shift that will completely transform the global manufacturing industry. It will change almost everything, the way we design, manufacture, distribute and consume.3D printer’s print objects from computer models to real 3D physical objects. The printing is done layer by layer using different materials. As different materials used for printing there are various techniques used for 3D printing, as well as the construction of the printer itself.

Project Objectives

Objective of this project is to design a low cost 3d printer using Arduino. The 3D printers can be used for both business purposes and as a hobby. The main purpose is to create items with only minimal material used. In industry products are made cheaply with mass production due to techniques such as injection molding to ensure there is no material wastage. These molds are far too expensive for ‘one of products’ and other methods can also be costly like cutting, sanding and finishing materials like wood, plastic or metal items. 3D printing allows people to create new ideas/ products, construct low cost prototypes and find replacement parts at a low cost.

•  To create successful low-cost 3D printer based of  Fused deposition modeling FDM concept.

•  To keep the design as much user friendly as possible while keeping.in mind people with non-engineering background.

•  To 3d print objective while keeping the costs economical.

Project Implementation Method

We will use Arduino Mega (mks gen2zv1.2) to control different parts of the printer.

It builds up a 3D model one layer at a time, from the bottom upward, by repeatedly printing over the same area in a method known as fused depositional modeling (FDM). Working entirely automatically, the printer creates a model over a period of hours by turning a 3D CAD drawing into lots of two-dimensional, cross-sectional layers—effectively separate 2D prints that sit one on top of another, but without the paper in between. Instead of using ink, which would never build up to much volume, the printer deposits layers of molten plastic or powder and fuses them together (and to the existing structure) with adhesive or ultraviolet light.

Benefits of the Project

The scope of 3D printing encompasses objects like aircraft components, musical keyboards, interactive posters, human organs, and much more , such as this 3D printed model of a child's heart.

Technical Details of Final Deliverable

Material extrusion or fused deposition modelling (FDM) uses a spool of filament which is fed to an extrusion head with a heated nozzle. The extrusion head heats, softens and lays down the heated material at set locations, where it cools to create a layer of material, the build platform then moves down ready for the next layer.

This process is cost-effective and has short lead times but also has a low dimensional accuracy and often requires post processing to create a smooth finish. This process also tends to create anisotropic parts, meaning that they are weaker in one direction and therefore unsuitable for critical applications.

Material jetting works in a similar manner to inkjet printing except, rather than laying down ink on a page, this process deposits layers of liquid material from one or more print heads. The layers are then cured before the process begins again for the next layer. Material jetting requires the use of support structures but these can be made from a water-soluble material that can be washed away once the build is complete.

A precise process, material jetting is one of the most expensive 3D printing methods, and the parts tend to be brittle and will degrade over time. However, this process allows for the creation of full-colour parts in a variety of materials.
