Introduction to 3D Printing

Major retailers like Home Depot, Microsoft, Staples, Sams Club and more are selling 3D printers in their stores, and the reliability and ease of use of printers are improving everyday.

While we are still in the early days of the technology from a consumer standpoint, the passion and excitement around this groundbreaking technology is going nowhere but up as new and incredible uses for 3D printers are found each day! While there are a number of different types of 3D printers on the market, they generally all have one thing in common: 3D printers use a digital 3D model file to tell a machine how to produce a physical object using a base 3D printer material.

How Does 3D Printing Work?

SLA printers are starting to expand their reach in consumer 3D printing. They use a photoreactive liquid resin as their base material instead of solid plastic filament. They work by curing the resin with a UV laser or a UV projector one layer at a time until the model is complete. SLA prints can be a lot faster, and many newer models have significantly better resolution than FDM printers, resulting in more detailed objects, but resin currently costs a little more than filament and the printers themselves are generally more expensive as well.

SLS printers are the main type of 3D printer used in professional and industrial applications worldwide. To create 3D printed objects, these machines use a high powered laser to sinter powdered material into the desired form. SLS printers work with a range of materials including plastics, metals and full color sandstone, making them the ideal choices for a number of applications.

This is the most common style of desktop 3D printer on the market today.

FDM printers deposit material in layers, building up an object a fraction of a millimeter at a time. They typically use plastic filament like thick fishing line as a base material, and create the object by melting down the filament and squeezing it out of a small nozzle to get precise placement. You can think of it kind of like an automated glue gun. This is a really slow process since every inch of every layer needs to be traced out by the nozzle, but these printers are also the least expensive.

Even within this category, there is a wide range of prices. More precise, consistent prints will require better printer parts, usually resulting in higher prices. Buying a printer made of cheaper parts may also lead you to have to maintain it more often or replace parts. Lower prices also usually have a smaller build plate, allowing you to only print smaller objects.

The most popular example of these kits are from the RepRap community, an open source printer platform. These open source 3D printer designs aid you in assembling and making sure you have all the necessary components and are supported by an active community of RepRappers who have built their own and are easy to contact in online forums.

More expensive parts, including using a higher quality 3D printer extruder design, will make the price of your kit go up, but they will likely result in a better 3D printer. The most commonly accepted file type for 3D printer software is. STL, while a number of other files types including. OBJ may be supported depending on the program. Most 3D design programs will be able to create. STL, you can convert it using a free 3D model converter.

Slicing is the act of converting the. STL or.

OBJ files into layers that the 3D printer can then reproduce to create the physical object. The result of the slicing process is usually a.

When printing starts, the 3D printer will follow the. GCODE instructions to trace out the object layer by layer as dictated by the slicer. In order to take full advantage of your 3D printer, you are going to need some great 3D models to print out. One of the best things about 3D printing is that you can create almost anything you can think of, and if you have the time and skills, you can design the files yourself. By the end of these lessons you should have a solid understanding of where you can implement this technology and why you should buy a 3D printer!

Throughout the course you will learn entry-level concepts behind 3D printing, the different kinds of 3D printers, various 3D printing materials and when to use them, and even some tips and techniques for how you can use 3D printing at home! If you want to learn about 3D printer operations or how to use 3D CAD softwares to design your own 3D models, you can continue on with the rest of our curriculum! Our additional courses cover more advanced topics, such as 3D printer operations and 3D modeling.
