Delta Printer Features

Many have heard about the already familiar 3D-printers, working on the coordinate system of Descartes. The print head in such devices moves in three axes (X, Y and Z). Recently, however, new so-called delta 3D printers using an innovative extruder motion system have been developed on the market. The print head in such designs is suspended on thin levers, with each lever attached to one of three vertically arranged guides.

What is the delta 3D printer, its features

Delta printers have the ability to print more structured and tall shapes. Their design is not overly complex. Matt Walters, an amateur engineer and inventor who designed and constructed a delta printer called Thingystock, says that most of the parts for the device he created can be designed even in "artisanal" conditions.

The aforementioned Thingystock is equipped with an extruder type E3D V6. The volume of possible "dimensions" of printed products is 150x150x150. The operation is controlled by an integrated RAMPS 1.4 processor. Through the liquid crystal screen is the correction of the work and settings. The approximate accuracy of the print produced is about one hundred and fifty microns. The total price of the device with replaceable belt pulleys, extruder fasteners and guides is no more than $ 550, which is actually a record figure for a 3D model.

Those who are thinking about purchasing a 3D printer for their own use should decide what result they want from the device. Models with Cartesian kinematics are usually delivered to the customer already in finished form and you can begin the process of printing on them almost immediately after unpacking.

REFERENCE! Models with Cartesian kinematics are most common, and it will be easy to find thematic Internet communities and forums on them on the Internet, which will indirectly facilitate their operation.

As for the delta printers, they are delivered in the form of prefabricated kits with instructions to them. It is sometimes quite difficult to find information about the nuances of working with such models, since they are currently less popular.

Pros and cons of a delta printer

Among the most relevant advantages of delta printers, experts point out:

  • the relatively low price of the device when compared with the "Cartesian" models;
  • high speed printing of materials due to the rapid movement of the head;
  • almost complete lack of noise at work;
  • more convenient design parameters for printing vertical objects;
  • low probability of distortion when printing due to compact platform;
  • compactness.

As for the main drawbacks of the so-called delta bots, they include:

  1. High demands on the detail of products, with the necessary coincidence of sizes up to one hundredth of a millimeter.
  2. The need to work mainly on 32-bit processors.
  3. High complexity of retract correction. In the case of installation of light direct extruders like "Titan", there is an increase in the mass of the effector and, as a result, a decrease in the print speed parameters. In addition, the installation of such extruders increases the cost of the device itself.
  4. Possible difficulties with calibration, which on more expensive systems are solved by installing auto-calibration systems.

REFERENCE! Experts recommend that those who decide on self-assembly of the "delta" at home, rely on ready-made working solutions, otherwise the problems with calibration and adjustment will not be avoided, which will increase the assembly time.

The best models of 3D printers delta

Below are the best models of printers in this category and their distinctive characteristics.

Mass Portal D300

The model has the largest construction area in the series, and uses high-temperature materials for operation. It operates at a temperature range of 475 degrees Celsius and has a water cooling system for the extruder. It is equipped with a camera with a volume of 300x300x300 mm and an average speed of movement of the head of 250 mm / sec.

3DQuality Prism Pro Dual

Specialized delta printer with automatic calibration and desktop heating system. The closed type of camera device allows you to not fear for the deformation of the printed product in the process of creation. The working chamber has a diameter of 400 and a height of 860 mm. The speed of movement of the head is slightly lower than that of the previous model, and is only 200 mm / sec. The device has two printheads and can be remotely controlled.

Delta WASP 2040 Clay

Irreplaceable model for those manufacturers who work with 3D-ceramics. Support for all types of ceramic materials, speed and accuracy, openness and compactness of this model makes it one of the best in its segment. The speed of movement of the head is about 150 mm / s. The volume of the working chamber is not too large: about 400 mm in height and 200 in diameter.

As a conclusion, it is worth noting that the production technology of modern delta printers over the past few years has been largely modernized. This has improved their functionality and ease of use.

These types of printers are used in the following areas:

  • architecture;
  • arts;
  • industry;
  • private use.

Despite the visible advantages, delta devices still require certain knowledge and skills to operate, and when choosing them, special attention should be paid to the parameter of the control board's width and the presence of the auto-calibration function.
