3D printers are by far the most innovative product that world has seen in the past few years and while at first they were something that only scientists or those with unlimited funds could access, these days 3D printers have become more and more affordable. Even so, those who are interested in buying a 3D printer for sale should take their time and do the proper research, as the lowest prices can start from $250, so they will still be making an investment. Even so, the prospect of being able to print virtually anything is definitely worth a closer look into this subject:
There are two main types of printers currently available on the market: the FFM or Fused Filament Manufacturing 3D printer that basically liquefies a plastic filament to create the desired shape and the SLA or Stereo Lithography printers that use an UV laser to create the solid shape. The FFM printers are usually easier to use and cheaper, which is why they are a more popular choice among those who have limited resources.
Depending on what you are planning to print, you will need to make sure that the printer you choose to invest in can deliver the expected results. FFM printers can use materials such as PLA, nylon, ABS (plastic similar with the ones used to make Legos), TPE (a soft, rubber-like material) and many others. SLA printers may offer fewer functions, but they can use resins to create very flexible products, so this might still be a more suitable choice for some people. The point is you have to think of your current needs and your potential future ones and choose the 3D printer that will work best for you.
Another important aspect you will have to look for is the build volume the printer you are investing in has. Naturally, you will only be able to build parts that are up to a certain size and the bigger the printing volume, the higher the cost. The limit of any printer is determined by the size of its bed and how far its print head will be able to move.
Printing speed is definitely an important factor as well and something that can be adjusted in certain printers. All items are printed in layers and the thicker the layer, the lower the quality will be. However, a high quality item can take up to 12 hours to print, even if it is not larger than 5 or 6 inches. Not all printers allow users to adjust the quality of the print, which is why it is an aspect you should look for before buying one, especially if you are interested in printing very detailed items.
These are just a few aspects that those who are interested in purchasing a 3d printer should look for, as they will help them make a better decision.
