What is a 3D printer, its purpose

A peripheral computer device that, using a digital volumetric model, creates a material object by layer-by-layer application of a rapidly solidifying material, is called a 3D printer. For the operation of such a device, a computer three-dimensional model is required, made in any of the 3D editors or obtained on a 3D scanner. Today there are several varieties, depending on the technology used:

  • FDM and DIW 3D printers using the extrusion method based on forcing molten material through a thin hole in a special device called an extruder (in printers of the first type, a thermoplastic heated to the melting limit is layer-by-layer applied to the cooled surface of the platform, and in the second - ceramic sludge, which called ink, thick ceramic slurry can be used in large architectural models);

    How a 3D printer works using SLA technology

    In 3D printers based on SLA technology, the product is formed in a bath filled with photopolymer resin. Under the action of UV laser radiation acting on a thin layer of resin, it hardens and the base goes down to the thickness of the next layer

  • printers in which an aligned layer of powder is used to create a three-dimensional material object, which is bonded in layers by different methods, by applying glue using inkjet printing (3DP printers) or melting it with an electron beam in a vacuum (EBM), laser radiation (SLS or DMLS, depending on powder type) and heating head (SHS);

    When using SLS technology, a thin layer of powder in the right place is sintered with a laser, and the printing platform is lowered to the thickness of the layer, and the entire space of the table is filled with a new portion of powder.

  • EBF 3D printers, which use a wire that melts under the influence of electron radiation to obtain a material model;
  • printers based on the principle of lamination, or layer-by-layer application of a film, in each layer of which the contour of the part is cut with a special cutter or laser;

  • printers with a point supply of powder melted by laser or electronic radiation;
  • devices working using the method of multi-jet modeling (MJM), when the method of inkjet printing is applied to a rapidly solidifying material;
  • bioprinters are innovative peripheral computer devices that are just beginning to be introduced, they use cells of a living organism to form internal organs, and in the future will be able to create a full-fledged material for transplantology (there are already cases of successful manufacture and transplantation of a jaw for humans and a thyroid gland for a laboratory mouse) …

How to choose: parameters to pay attention to

When buying any complex device, you need to clearly define for yourself the purposes for which you are going to use it. This will determine what operating parameters it suits you best. Considering that such a peripheral device is not cheap, you should select it most carefully, taking into account all the operating parameters, so that you do not regret the purchase later.

First of all, you need to decide on the type of printer for the 3D printing technology used. The most popular and affordable models today for home use or small business are:

  • FDM printers, which use various types of polymer filament as a material, and have a fairly good print quality and the lowest price;

  • SLA devices on photopolymer with higher print quality and price, ideal for jewelry production;

  • the most expensive of the peripheral devices of this group are SLS-type devices that melt the powder with a laser, it is impractical to buy them for the home, and they can only be suitable for business, due to their high cost (up to 30 thousand dollars).

Among the main selection criteria are the following:

  1. The type of media used for printing. When choosing a 3D printer, you need to take into account that consumables for FMD devices will cost less than for SLA printers. For those who decide to purchase an FDM printer, there is a large selection of plastics of different colors and types (PLA, ABS, HIPS, PVA and others), but PLA plastic filament will be ideal for beginners, since this material is easier to use, and products from it are perfectly flat and smooth. Those who choose the SLA 3D printer will have to purchase more expensive material in the form of photopolymer resins. For non-professional printers, it is best to buy a photopolymer of the Vera, Somos or Tanga series, which are distinguished by transparency, high strength, heat resistance and plastic stability.

  2. Accuracy of printing. It is higher for SLA printers. The accuracy of the model reproduction in devices of the extrusion type largely depends on the thickness of the layer that is laid by the printer during printing. This means that the thinner the hole of the extruder nozzle, the higher the clarity of reproduction of the digital model in the material object. Today there are models of printers with different nozzle hole diameters from 0.1 to 0.4 mm. It should be understood that the smaller the hole of the extruder nozzle, the longer it will take to make the model. Here everyone has to choose for himself what is more important for him - the accuracy of the 3D model display or the printing speed.

    The top photo shows a detail made on a 3D printer with an accuracy of 0.1 mm, and the bottom one - 0.025. With greater print accuracy, the product is smoother, without visible plastic layers

  3. Printable area, which determines the maximum size of an object that can be printed by this printer. There is, of course, the ability to make larger objects, but only in parts, gluing them together with a special glue. To do this, using the 123D Make program, the digital model is split into separate parts. But, if you do not want to engage in gluing, then when choosing a printer, compare the desired dimensions of the manufactured layouts with the printable area of ​​a particular model.

    The maximum space that a layout can take on a 3D printer is its printable area

  4. Design features. Here it matters whether it is open or closed, and from what materials the body and bearing elements are made. These factors most of all affect the rigidity of the entire structure, on which the speed of movement of the print head depends, as well as the ability of the bearing parts of the device to damp vibrations and vibrations from several electric motors responsible for moving the printer head along all three axes (X, Y and Z) and its table along the Z axis. The case, made of wood, may seem too budgetary to some, but it perfectly absorbs vibrations. Bearing structures made of aluminum or steel will be stronger and more durable. It is better to buy SLA printers with a well-ventilated working chamber, which will facilitate faster curing of the photopolymer. And for FDM type devices,especially when working with ABS plastic or nylon, which have a high degree of shrinkage during rapid cooling, it is better to purchase a 3D printer with a closed case and lining of the working area.

    Closed printers (photo on the right) are more rigid and can achieve faster print speeds.

  5. The presence of auxiliary software. 3D printers are high-tech computer devices that require special software to operate. First of all, a 3D printer must recognize and be able to read all 3D editors and various data entry formats. The latter include the STL and X3D languages, as well as the VRML standard. There are many auxiliary programs that allow you to perform a wide variety of actions for preparing for printing and creating a material model. These are, for example, slicer programs that allow you to cut an object into parts for printing in parts (Kissslicer or Cura) or 123D Catch program designed to work with a cloud service, and allows you to get a three-dimensional digital model of an object from its photographs taken from different angles. Availability of auxiliary programs,supplied by the printer manufacturer, greatly facilitates the handling of such technically complex devices. And this fact should also be paid attention to when choosing them.

The most suitable 3D printers for small businesses

Bulk printing using 3D printers is the most promising direction for small businesses today. With the help of these computer devices, which do not require too large financial investments, as for industrial printers, it is possible to establish small-scale production of various goods.

Of the large variety of printers on the market for these purposes, models that meet the following criteria are most suitable:

  • print quality must be high enough to create unique and realistic models that are interesting for sale, which immediately excludes relatively cheap printers from the choice, costing up to $ 1000;
  • it is desirable that the printer be adapted for color printing (FDM, DIW, 3DP or EBF printers), which will save time for coloring the product in small-scale production;
  • the device must support work with at least two main types of plastics (PLA and ABS), which will expand the possibilities of its use, and will make it possible to produce products for children (PLA plastic is intended specifically for children's goods);
  • the price of consumables used by a 3D printer should provide an acceptable cost of finished products, sufficient for a normal level of business profitability;
  • the size of the working chamber should correspond to the dimensions of the models provided for production, while it should be borne in mind that printers with a larger print area will cost more.

In any case, the choice of printer will depend on what kind of business you intend to do. For the production of small crafts, devices of the extrusion type are suitable, and for the manufacture of jewelry or dentures - more expensive printers on photopolymers. Among the most suitable for small businesses are the following models:

  • Flashforge Creator Dual, with a working chamber volume of 5.2 liters and two extruders, the printer supports work with three types of plastics - ABS, PLA, PVA and has a printing accuracy of 0.1 mm;
