Introduction to 3D Printing
Slide 1 Introduction to 3D Printing 3D Printers 3D printers are used in designing and prototyping, and production process. The objects that are created in these printers can be of any shapes, sizes or geometry. Today's 3D printers had their start in the rapid prototyping (RP) technologies of the 1980s and found their use in the industrial market. As patents expire, 3D printing technology is becoming more available to consumers. The 3D Printing Process 3D printers build objects using a process known as additive manufacturing. Material is put down in layers; each layer adds to the previous layer and in turn becomes a base for the next layer. Most 3D printers in the consumer market use thermoplastic inks in the printing process. These polymers become soft and pliable within a temperature range and then resolidify when allowed to cool. How do 3D printers work? These printers first formulate the fundamental design of the object that you desire to form. This plan is made through a CAD file which applies 3D modeling program which is used to make a new project or it can also use 3D scanner which duplicates the exact model of the object and also builds a 3D digital file of the object. These scanners put together different techniques for making 3D models. For making a digital file for printing, the software used in 3D modeling splits the final model into millions of layers. Technology used in the 3D printers Different types of 3D printers make use of different technologies. There are many ways that are available for printing that merely differs in the manner by which the layers are built to complete an absolute entity. While some of the technologies use the process of melting to produce the layers for which they utilise the process of either selective layering or fused deposition. One of the most widely used technologies is Stereo lithography. It also makes use of other technologies like Vat photo polymerisation, material jetting, sheet lamination, powder bed fusion and many more. 3D Modeling The printable 3D models can be shaped using CAD package or 3D scanner that uses plain digital camera and photogrammetric software. 3D scanning procedure evaluates and saves digital data and makes it materialize as a shape of a real object. Based on this technique, three dimensional models can be produced. Irrespective of the 3D modeling software used, this 3D model gets converted into .STL or .OBJ format to allow the software that prints the object to make it readable. Applications of 3D printers 3D printing finds many applications in various sectors of industries from automotive to aerospace and aviation to bioprinting and healthcare instruments. 3D printing can also be of great use in creating objects of day to day use, and personal projects. The technology of additive system can deduct your time from being wasted and help to print the object in few hours. 3D Printing Services 3D printers are expensive and not everyone can afford it for their individual purposes, and so there are various companies and firms that offer 3D printing services. There are also online 3D printing services which deliver 3D printing services at economical price range and can print and deliver any object from a digital file that you upload to their website. Finally, It's Fun! For engineers, makers, and creators, it's a fun time to get into 3D printing. Many sites offer files for download, and there are options to utilize 3D printers even if purchasing one isn't in your near future. As 3D printers become more commonplace, more and more uses will become available. Thanks
