3D printing is more than just useless figurines

When building a 3d printer it is good to have some idea of ??how this device works. Every builder probably knows what FDM technology is, which consists in modeling an object from molten plastic, squeezed through a nozzle. Perhaps it is also worth knowing what the individual parts of the printer are for, which will facilitate not only the assembly, but above all, the subsequent diagnosis of problems. Taking advantage of the opportunity that the parts are slowly reaching me, I will describe what it looks like in the case of Graber i3, whose construction I am starting . Many of the parts are so universal that they are common to most devices. In particular Graber i3 is very similar for the whole family based on Prusa i3 – with accuracy to the
frame structure and the number of printed parts. I hope that anyone who would like to build a 3d printer, and not quite know how to do it, will find something for themselves in today’s post.

The frame is the main structural element of druk 3D szkolenie the printer, maintaining its stiffness. The rest of the printer is attached to the frame. The frame can be made of various materials – wood, metal, plastics, in various combinations and quantities. The frame of my Graber i3 was cut from a 6mm thick MDF board. Graber is characterized by the fact that most of the structural elements (such as engine mounts, table base, engine holders, or cart / head carriage) are made of the same material as the frame. This is a bit of the idea of self-reproduction” of printers (which is still a fiction), but it suits me.

To protect the frame and get rid of the unpleasant odor of burned MDF, I painted it with water-thinned enamel Beckers Designer Universal in the color of “melon”. The color was determined by the sale in the local store, and I trust Tikkurili for its producer. The paint does not stink, it dries quickly, the tools are washed with
water, and in addition I did not want anything flammable. The first layer hides poorly, but it should be treated as a foundation (according to the manufacturer’s suggestions), while each of the following layer gives the right effect. I painted 2-4 layers (depending on the element) mainly with a roller, the smallest elements
with a brush. The whole operation requires a lot of patience due to the number of parts, but it went without a hitch.
