3D Printing- A modern way of making objects

-By Monika Sachan

3D Printing which is other times referred to as additive manufacturing is simply a three-dimension object basically from a CAD model.3D printing may also refer to processes whereby, materials can be deposited, combined, or solidified to make a three-dimension object through the help of a computer. Below are some facts you need to know about 3D Printing technology.


3D technology is becoming more popular and it’s gradually overpowering the traditional way of making objects in some industries. 3D printing uses computer technology to make 3 dimensions objects The process involves purely arranging of materials into a horizontal cross-section of layers to print solid objects such as machine parts gun and toys are good examples of successful 3D technology. A Japanese Inventor, Hideo Kodama, holds a record as the first person to invent the use of the technology in 1981. He manufactured solid objects by using ultraviolet lights to harden polymers.

Selective Laser Sintering is more advanced compared to previous ones, the technology uses additive manufacturing and also polymer powder, pure nylon to make the objects. As the name suggests, the technology uses a laser to mix the powders together layer after layer to make more complex shapes.

Scott Crump, developed Fused Deposition Modeling form off 3D printing, the process involves heating of thermoplastic cable into liquid form then eliminated layer by layer. For instance, this is the commonly used form of 3D printing, it is also referred to as a desktop 3D printer. The use of 3D printing technology has changed and contributed a lot to the development of manufacturing industries

Top Four Application of 3D Printing

Below are some effects on introduction of 3D printing technology in a number of industries. They include

  • Medicine

3D Printing technology has been more important in the world of medicine for the last couple of years. The technology has been employed in areas such as Bioprinting to help in the making biomaterials such as cells and growth factors combined together to make tissue-like-structures to produce an imitation of natural look alike.

In the area of prosthetics, 3D printing has been used to make simpler and less expensive prosthetics that is suitable for the patient, for instance, children who are in need of prosthetic used to wait for long in order to get a prosthetic that they will not outgrow, nowadays it is easy to acquire one with the aid of 3d printing after every few months. In most developed countries, they have taken the advantage of technology. (Rance Tina, n.d.)

In the field of medicine, the application of 3d printing is used to make metal orthopedic implants since the application has enabled the making of porous surfaces. Their many cases of patients getting a successful titanium pelvis implant or someone having a new titanium lower jaw, in other cases a motorcyclist can get involved in a road accident and got serious injuries on his face, with the help of 3D printed parts he will have it rebuild.

Also, in the field of bioprinting, it is easy to print artificial organs which helps to solve the issue of kidney failures to patients faster, which is nice to the health sector and to the patient as well. Some 3 D printed tissues have been invented to be used in the pharmaceutical field to help in determining the cost-effectiveness and also assist in examining any side effects of drugs and help to identify the best dosage.

Through the application of 3d printing, pills are manufactured by applying Binder Jetting process, however, the pills are made to be porous hence high dosages in a particular pill which is easily dissolvable for easy digestion. Good news for treating epilepsy.

Scans of animal hearts have been used by researchers at Washington University in St. Louis who created printed models. A stretchable electronics peeled off silicon device can be taken out of the printed model and attached to a human heart as desirable.

  • Construction

3D Printing offers a couple of technologies in the field of construction, for instance, is used in extrusion, which includes, concrete, wax, foam and polymers. Also is used in powder bonding, that is polymer bond, reactive bond and sintering and lastly in additive welding. 3D printing is widely applied in the private commercial, industrial and public sectors. The most important as to why the technology has been mostly used is that there are more complexity and accuracy reduced labor cost, less wastage of materials without forgetting to mention faster construction hence saving time. The first residential house was build at (Yaroslavl  Russia, 2017 (website) (Placeholder3)). 3D printing was applied to print 600 elements of walls which were printed in a shop and brought to the site. Thereafter, they completed the roof of the building then finalized on interior decoration, covering a total area of 298.5sq meters. The project is the first worldwide to employ 3d printing technology in the house construction sector process.

Concrete 3d printing is a faster and a less costly process of construction of structures, use of large scale 3d printers are used purposely to print concrete that can pour a foundation and also build walls on the site.

The first pedestrian bridge to employ 3D technology was printed in Alcobendas, Spain, they reinforced concrete for 12 meters of length and 1.75 meters of width respectively. The whole project was laid through the use of a set of rules, values, that guide designing. 3D printing is being studied in the school of construction as the new technology in the area of building houses and structures, the technology is mostly targeted to be employed in the construction of extraterrestrial habitats on moons, mars. These habitats will only require ten percent of structure to be taken from the earth through lunar materials.

  • Prototyping and Manufacturing

3D printing technology was purposely developed to enable faster prototyping, the most important about the application is that is more affordable and flexible for small-scale manufacturing and prototyping. Contrary to an injection-molded prototype which is costly to use and also will not save time. The application of 3D printing is friendly and suitable when printing a few products. Some big companies such as Mahle (mahle) well known for automotive parts supplier, employed 3D printing technology.

  • Education

Many schools are introducing 3D printing technology into their curriculums. The importance of incorporating 3D printing is to prepare learners on how to make prototypes without the use of expensive tools. Students apply the application through designing and also producing models which they can simply hold, in other words, 3D printing acts as the bridge between ideas on paper or on a screen to the creation of the same ideas to physical objects hence, 3-dimensional world.

Most schools and universities are now introducing 3d printing for learners to use in classes and on their projects. Maker Bot company encourages the introduction of the new technology by giving out certificates for both teachers and students.

Learners acquire more knowledge about varieties of 3d printing applications through venturing into designs, architectural principles and engineering fields, therefore, science students are able to learn a cross-section of human organs and other specimens.

One such example of Using 3D printing for educational purpose is presented below:

How 3D Printing Works

The process includes a sequence of steps that are necessary for making any object, the process comprises of

CAD Model,

The cad model is the first step and also the most delicate element which without it an object cannot be produced. The model is either manufactured in a 3d modeling software example is Solidworks or through reversing of engineering by using a 3d scanner.

Slicing Software

The process includes converting STL files in a way that 3D printers can read hence imported into slicing software. The software thereafter controls the range of parameters responsible for high-quality 3D printing results.

3D Print

The 3D print is the last step, whereby, the sliced file from slicer software is directed to 3d printer. Through the press of the printer button, the 3D printer will print the objects layer after layer.
