It is almost more expensive to purchase the required parts separately. Because I am planning to build a larger laser cutter, I have decided to use the Anet A8 parts for this. The Anet A8 printer is a very cheap printer and after some improvements you can get very good results. In a previous Instructable I converted my Anet A8 printer into a cnc machine and a laser engraver. But It is also possible to use another 3D program such as, for example, Fusion 360. Letters, drawings and even images can easily be converted into 3D objects. This is an online program that can be uses to create (simple) 3D objects. I've used Doodle3D to create 3D objects easily and quickly. This makes it is possible to place LED lighting inside the object. Most objects in this Instructable are printed with transparent filament. And it's therefore mainly a display object. There are some limitations: The entire object is printed hollow, without any support. This makes it possible to print an object of about 3 x 4 x 1 inch within one hour. In this instrucable I will speed up the printing process by making relative large objects with as little material as possible. The layer height must always be lower than the thickness of the nozzle. However, the layer height is limited by the nozzle size. The fewer layers, the earlier the print will be ready. But it requires a sturdy frame to be able to print at high speeds. You can increase the speed at which the print head moves. There are different ways to speed up the printing.
This is because these printers stack thin (0.1 to 0.2 mm) layers of plastic on each other. The main drawback of these printers is the time it takes to print something. For the price of a DIY printer from a few years ago, you can nowadays buy a ready-made large 3D printer. Partly because these have become more affordable in recent years. Nowadays 3D printers are available at more and more schools and other locations (like Makerspaces).
And all children watched attentively during the time it took to print the item. This isn't the fastest 3D printer, and It took about 40 minutes to print a very small object. I used a small Up Plus 2 printer which always works fine. A while ago I gave a 3D printer demonstration at a primary school.
