The current 3D printers offer is varied in the spectrum of the hobby, semi-professional and professional equipment. How to choose? It may be simple but it's also the final option may require inspection and test prints. Consider what parameters are important for us, and what less or not at all. The following lines is given a basic and very indicative overview.



-          What you will print the most frequently-the approximate character models, size, their use on, etc. (the size of the construction Chamber, material, printing technology)

-          The precision of the detail (the ability of resolution, height, layer, printing technology)

-          What kind of strength to meet the models (material of the printout, and printer's ability to reliably print it)

-          The complexity of the models/need (the ability of the current print model and easily remove support)

-          The speed and the number of copies in the desired time (printing technology)

-          Ease of operation and the use of it (the necessary operations before printing)





Intended for: Home (non-professional) print

Materials: ABS, PLA, NYLON...

Benefits: Low cost, relatively high strength

Disadvantages: supports, accuracy of about 0, 5mm

One of the most widely used 3D printing technologies. Thanks to the low cost of the printing is possible with this technology 3D printers use to be in schools, households, etc.



SLA (stereolithography)

Intended for: Professional printing (goldsmiths...)

Materials: photosensitive resin

Benefits: very high accuracy, high resolution printing


The oldest technology of 3D printing its accuracy still surpasses all others. The quality of the surface, the building dimensions, reliability, wide range of materials. This and many other makes of plastics prototypes, one of the most widely used technologies today. With this technology, the printer may have a resolution equivalent to 4000 DPI with more consistent mechanical properties in all three axes than other printing technologies.



SLS (selective laser sintering)

Intended for: Professional printing

Materials: NYLON (+ various mixtures)

Benefits: High strength and precision parts, suitable for practice, good materials

Disadvantages: Price of printing

A powerful force of the laser! This technology is used with very hard materials for creation of functional prototypes. Material in the form of dust (nylon with various admixtures) is sintering with powerful lasers. The resulting volume is very resistant to many kinds of stress.



CJP (colorjet printing)

Intended for: Professional printing

Materials: gypsum

Benefits: the option "full color" print (up to 6 million colors), high accuracy, full support

Disadvantages: Price of printing

ColorJet Printing is the technology of 3D printing, which allows you to print photorealistic models. Uses up to 6 million while the palette of colors. It is therefore appropriate for such a sector where it is important such as color representation of design or architecture. Print software cuts the virtual 3D model on each 0.1 mm thin layers, and then one after the other is sent to the printer. The always spread after the press backing as a thin layer of building materials and the print head draws a cut as a normal inkjet printer. Then apply another layer of the material and the process is repeated until the entire model is finished. After you finish you need to clean the model from "soft" material and immerse him in a special infiltrant (special liquid), which gets the final hardness and a clear color.
