Metal, rubber, plastic, or concrete and gypsum. These are all the materials from which you can print today. It just depends what kind of 3D printer you have available and what the copy you need. For printers that are available for both the home and the school, with prints of plastics ABS (Akrylonitrilbutadienstyren), PLA (Polylactic-acid of polylactic acid), nylon, also the WPC (wood plastic copolymer) and PVA (polyvinyl alcohol). Professional 3D printing of plastic are used mostly mixtures of ABS + Polycarbonate, nylon and more. When a professional 3D printing in metal are used metals such as titanium, stainless steel, high strength steel, and their mixtures. In this article, however, we will dedicate the resources from which you can print at home.
This material is the most widespread, as regards domestic (retail) printing. It is the material from which they are made and the familiar LEGO parts. When used in the 3D printing material and different colors. In the original neobarveném implementation is white to cream in color.
Material is good for: beam, gear, spring, screw/nuts, plugin
Benefits: - health and safety
- good mechanical resistance to temperatures of around 100 °C
- the relatively high strength (all types of stress)
- excellent toughness
- good "workability" after printing (grinding, cutting ...)
- from the material can print parts with minor details (threads...)
Disadvantages: - at low temperatures (below 0 ° c) it is possible that disturb its surface
- a higher melting temperature (approx. 260 °C)
- not every printer supports ABS plastic (mostly due to the temperature of melting)
Material at first used more on support. That is the plastic from natural material (lactic acid) can be called. wash out using sodium hydroxide. The process of washing is done, when we have a part of, for example, material ABS and supports from the material PLA. The whole printed piece and with inserts in an ultrasonic bath, where the dissolved sodium hydroxide. After about 4 h washing away, when it must be heated to hydroxide approx. 60 ° c will dissolve the material PLA literally and are only required to remain part of ABS plastic.
Material is good for: art objects, accessories, covers on mobiles, holders
Benefits: - excellent material on supports
- higher hardness than ABS
- part have better surface
- less melting temperature of approx. 160 °C
Disadvantages: - the worse the "workability" of printing (cutting, grinding etc.)
- a small thermal resistance
- greater fragility due to higher hardness
This material is best suited for parts for practical use in terms of home 3D printing. Nylon is basically an improved ABS plastic, as is the stronger, more resistant to higher temperatures than the ABS and has a greater life.
Material is good for: gear box, gear, shaft, plugin
Benefits: - very high strength
- the most suitable for the practical parts
- excellent heat resistance (approx. 150 °C)
Disadvatages: - longer print times
- the higher cost
