3D printer: the great potential of volumetric printing

3D printers, also known as printers for three-dimensional printing, are innovative devices that are used to create volumetric models. These specialized machines offer endless possibilities and are now widely utilized in various sectors of modern life. Until recently, 3D printers were primarily used by large businesses, but now they are also accessible for home use and smaller enterprises.

History of appearance

The inception of such equipment can be traced back to the mid-1980s, however, due to limited advancements in computer technology, the active implementation of 3D printing was put on hold. Significant progress was made in 2005 when 3D printers started to gain traction alongside the improvements in computer capabilities. During this time, the first 3D printer capable of printing in color was publicly introduced. Since then, the technology has undergone numerous modifications and the development of modern software has allowed for better control over the printing process. As a result, users now have access to a versatile device capable of creating phone cases or even new 3D printers.

How it functions

The basic principle of operation of a 3D printer in theory is straightforward and comprehensible. In a 3D modeling software, an object or a portion of it is generated (for larger models, they are divided into multiple components). Subsequently, the file is transmitted for processing via a specialized software (to generate a G-code), following which the technology is in motion. The G-code divides the digital model into numerous horizontal paths, determining the trajectory for the printing carriage. The liquefied material is applied layer by layer onto the base, fabricating a tangible object.

• The most commonly employed technique for 3D printing and culinary applications is known as Fused Deposition Modeling or FDM printing. This entails heating a material and extruding it onto a platform via a nozzle located in the print head. The object is built layer by layer on the platform, with its size being constrained by the platform’s dimensions.

• Polyjet technology, which is currently owned by Stratasys, was first developed in 2000. This technology enables the creation of three-dimensional objects by polymerizing photopolymer under the influence of UV radiation. Photopolymer, which is an expensive and delicate type of plastic, makes these printers impractical for everyday use. However, they are widely used in medicine and industry for precise detail modeling and prototyping purposes.

One can acquire knowledge about the functioning of contemporary 3D printers that employ "plastic printing" through specialized videos, such as the one provided here. Furthermore, these videos often showcase the printer’s versatility in working with diverse materials to produce various objects.

Control of the printing process

Typically, before starting the printing process, the user is required to adjust several settings.

1. The equipment is connected to a PC using a USB cable.
2. The nozzle movement is calibrated in relation to the platform.
3. The heating of the platform and nozzle-dispenser is set up and controlled.
4. The temperature ratio is monitored.
5. The printing process (extruder) is controlled by adjusting the material feeding speed and replacing plastic bobbins.

The printing process is controlled through a PC. To transform an idea into a physical object, the user needs specialized software for 3D modeling and machine control.

Currently, it is not yet possible to design a printer that can perform all tasks with just a few key presses. Therefore, it is important to familiarize oneself with a variety of specialized software programs and gain a basic understanding of 3D modeling.

Prior to commencing the printing process, the operator must calibrate the printer by adjusting it to the tabletop platform. The printer’s firmware comes with a set of default settings, but the user can make more precise adjustments depending on the type of material being used. For instance, different melting temperatures are set when creating volumetric elements using ABS or PLA. Throughout the printing process, the operator keeps an eye on the progress using the accompanying software. The entire model creation process can take anywhere from a few hours to a full day, with the accuracy of execution being a critical factor. Precise objects with intricate details take longer to produce compared to simpler designs.

Where 3D printers can be used

The usage of 3D printers has a broad range: from hobbies to business. Business owners and students in architecture were the initial ones to recognize the immense possibilities of "plastic printing".

1. Developing and producing three-dimensional models of different structures.
2. Producing plastic components for machinery: protective covers, gears, handles. Another area of focus is the production of parts for imported vehicles, which is quite logical considering their price.

In addition, volumetric modeling finds application in the field of jewelry as well as various domains of design and engineering.

Back in the day, plastic was the primary material used for printing, but nowadays there are a wide variety of options to choose from. Manufacturers have developed various bases that can even mimic the appearance of natural wood. And it’s not just polymers that can be used as printing materials – nylon is also a viable choice. Designers quickly caught onto this idea and began creating entire collections of clothing using this new printing technique.

Collectors who enjoy gambling will be thrilled by the possibilities that "plastic printing" offers. Now it’s possible to recreate any object, whether it’s a model plane, a famous character, or a work of art. Rare collectibles can be quite valuable, just like a high-quality printer for your home. The choice is clear in this case.

To take or not to take: advantages and disadvantages of the equipment

The utilization of volumetric printing provides users with a wide range of opportunities. The primary benefit of this technique is the ability to replicate any three-dimensional object, with very few exceptions. Essentially, anything that can be constructed from plastic has the potential to be "printed," whether it is an expensive bumper for an imported automobile or a design for a forthcoming shopping mall at an architectural exhibition. The determining factor in this process will ultimately be the dimensions of the equipment, or more specifically, the size of its work surface.

The labor-intensive nature of preparation and management is a hindrance to the full potential of "plastic printing," as it necessitates specialized expertise. Designing even a basic geometric shape or one’s own portrait in 3D-MAX can prove challenging for an inexperienced user. Mastering the technique requires investment of time and effort.

The size of the 3D printer is another drawback. While there are compact models available for sale, their printing capabilities are limited, although they are suitable for step-by-step production of installations or architectural projects.

It would be impractical to purchase a 3D printer as a toy, as the average cost of models in the affordable range exceeds 30,000 rubles. However, purchasing a 3D printer would be a profitable investment if it serves a specific purpose, such as generating profit, developing skills, receiving education, fostering creativity, or aiding in work.

In the coming future, we can anticipate exciting advancements in this particular domain. At present, it is already feasible to fabricate an actual residential dwelling using conventional construction mix through the process of printing. Needless to say, such sophisticated machinery is not yet accessible for domestic purposes, but the mere utilization of innovative materials for printing paves the way for systematic augmentation of volumetric printing capabilities in residential settings.
