3 D printing is also known as additive manufacturing. It is a process of preparing 3 D objects out of a digital file. The process of additive manufacturing or 3D printing is done by layering the material (thin layers) till the creation of the desired object. This is a very innovative methodology of the 21st century wherein you can create an object out of a simple digital file.
The 3D objects get created by first starting with a virtual design i.e. a Cad (Computer Aided Design) of what you finally want to create. Either a 3D modeling application or a 3D scanner is used to create the CAD file.
3D modeling software
3D modeling software can cost you a few thousand dollars a year per license and it comes in different forms as well. However, you can also find some open sources where you can find beginner video tutorials. One of these open sources is the Blender. But if you are a beginner, we recommend you to begin with Tinkercad. Tinkercad works on Google Chrome and has an option of even getting your object printed through 3D printing devices.
3D scanners To create a 3D model, the 3D scanners use varied technologies like using the time-of-flight, volumetric scanning, structured or even modulated light. In future, Mircosoft and Google aim to digitize real objects into 3D models by just taking a picture. Their plan is to have the next generation of smart phones 3D scanners installed in them. This will make it much cheaper than the current 3D scanners which today come in the range of approximately $30.
Tips for Buying A 3 D Printer
Here is a 3d printer guide for your next purchase. We have listed out some of the key points to keep in mind when you go for your next buy of a 3D printer.
* Size: The bed size or the table of the printer is one of the important criteria to keep in mind. The large the bed size or the table of the printer, the larger objects you will be able to print.
* Price: The 3D printers can of course more expensive as most of them can be anywhere between $1500-2500. But you can end up finding some models cheaper than this. If you are planning to buy 3d printers under 500USD then here are some assembled as well as non-assembled options for you but not all of them are available over the shelf. Some of these you might have to obtain by donating on their project.
* Type of Polymer: The type of polymer used is also an important factor in this case. There are two types of filaments that are used for a 3D printer – Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA). There are the two best known thermoplastics. Though ABS is a strong and slightly flexible plastic, but it also has an odor that might be
unpleasant for some people. On the other hand, PLA is a biodegradable polymer made from sugar. It also has fewer tendencies to warp and it is better used if the printer table isn’t heated. However, PLA may be a bit more brittle than ABS. You can also get affordable PLA and ABS filament in the market which can work well.
* Best Reviews: One of the best ways of choosing which 3 D printer is most sought after and value for money is to go through the 3D Printing Supremacy 2016/2017.
