The best 3D printer

Najbolji 3D štampač

Of course, there is no such thing. Because each device has its advantages and disadvantages.

In this text, we are first of all considering the printers that we have selected, because we believe that they are among the best and unique in their purpose. And our opinion is shared by the majority of 8,624 printer users registered on the world's largest site for service 3D printing - 3D Hubs https://www.3dhubs.com/best-3d-printer-guide The main features of these 3D printers are: print quality, reliability, ease of use, quality support and excellent value for money. What defines the purpose of a printer is the materials it works with. Each printer in this field has its own specifics, advantages and disadvantages. Of the materials, the most resistant to chemicals is CPE+, which is essentially PET with impurities, which is inert to all types of bases, acids and acetone that we tried. Ultimaker family 3D printers work best with it. A very interesting material is also PC (polycarbonate), which is very strong and stable up to 110⁰C. The strongest non-composite material. TPU (Thermoplastic Polyurethane) 95A which is flexible, yet highly chemically resistant and wear resistant. Among the special materials, there is also the Material ABS CarbonX http://www.3dxtech.com/carbonx-carbon-fiber-abs-3d-printing-filament/ it can easily be used on Ultimaker 2+ printers and thus increases toughness and mechanical resistance, but it is still ABS which is very porous to acetone and a lot of thinners. The main limitation of the Ultimaker 2+ is that the same material is used for the support, so it is impossible to print very complex shapes, because the same support cannot be removed. This is solved with the Ultimaker 3 family of printers. Because it has a head with two extruders, it is possible to combine Nylon and PVA material that dissolves in water. You can see it the fastest here https://www.youtube.com/watch?v=oeJLLC2NJQs Nylon is a material with good physical and solid chemical characteristics (resistant to bases, organic solvents and acetone, but not to acids). Furthermore, we have the Form 2 printer, which definitely has the highest finishing of the desktop printers and considering that it works with a laser for resin, it is much faster than all FDM printers. This printer has very good materials for engineering use. One is extra strong, the second is elastic, the third is resistant to high temperatures up to 289 °C, making it the most temperature-resistant material on the market, the fourth is mechanically durable like PP, the fifth is specially used as a casting material. The main disadvantages of this printer are the size of 145x145x170mm and the higher price of the material. In this whole story, it is necessary to add the excellent printers of the company Markforged. With their printers, material that strengthens the print is pressed into the building material (Nylon or Onyx) with a special head. And this results in elements that have higher durability and strength than aluminum. Here I would single out the Mark Onyx Pro, which combines Onyx (nylon with microfiber carbon) which is reinforced with fiberglass. As for chemical resistance, it is similar to nylon (resistant to bases, organic solvents and acetone, but not to acids). The main limitation here is that the support is made of the same material as the object, so it is impossible to make very complex shapes. The X model has almost appeared, which, in addition to better stability in operation, also has laser control during printing. In the middle of this year, a printer will be released that will work with metals (stainless steel, aluminum, tool steel, inconel and titanium). If you need a very large printer, there is a BigRep with a working volume of one cubic meter 1050x1050x1050mm and two heads for work. Two more smaller models will appear in a few months.
