10 Fundamental Questions about 3D Printing

Author: Mukesh Kumar
3D bio-printing is the method of generating spatially-controlled cell patterns using 3D printing technologies, where cell function and feasibility are preserved within the printed construct. Unlike traditional methods of manufacturing, remove material from larger pieces by cutting, drilling, and carving to create a final part. Here are 10 fundamental questions and answers about 3D printing.
1Q: How do 3D Printing work?
3D printing is a relatively new technology, which involves use of substances unlike ink printing on paper. 3D printing involves layer by layer building up of a product.
2Q: How to try out 3D printing?
Earlier 3D printing was used as a technique available only to the researchers in labs. But today, with the technological advancement, this equipment has entered even in homes. So trying out 3D printing has become easy.
3Q: What are the softwares to be used as a beginner in 3D design?
There are extensive softwares that could be used with regard to 3D printing. To begin with, the best application is Google Sketchup that helps you to design everything you require in 3D. This app also provides free 3D models to download. Other examples are Wings 3D and Sculptris.
4Q: What are the significant applications of 3D printing?
3D printing is used to make souvenirs, guns, toys prosthetics and mockups of patients’ different parts of the body for medical treatment.
5Q: What could be the 3D printing expense?
There is an initial amount involved in 3D printing for the printer. Later stage there will be maintenance charges on printer, software and the filament.
6Q: Is it easy to learn 3D modeling?
3D modeling could be learnt through modeling tools like Rhino, Blender or SketchUp.
7Q: How to start 3D printing at home?
It is to start 3D printing. First get the 3D printing software, after that get a 3D printer and raw materials.
8Q: What are the types of materials that you can print?
Commercial 3D printers are capable of printing aluminide, glass, sterling silver, ceramics, sandstone, silicone, cement, plastic, metal, paper and wood. Researches proved that people can print using bone or organic tissue, or on molecular level. Hobbyists could print with sand, sugar and even chocolate.
9Q: What are the functions of 3D printing?
The functions of 3D printing are: Additive manufacturing, building parts layer by layer without a mould or scaffolding, single piece complex parts customized based on digital designs created from CT or MRI images, truly personalized device using patient’s own medical imaging. It also used as an alternative device production method for traditional components or as a primary method to create patient-matched devices.
10Q: What are the major Technical Challenges in 3D printing?
Process verification and validation are the major technical challenges. These are especially important when products are produced individually or in very small batches.
