What are 3D printers and its types?

3D printers are devices that can create physical objects from digital models. There are several types of 3D printers available in the market today, each with its own set of strengths and weaknesses. Some of the most common types of 3D printers include: 

  • Fused Deposition Modeling (FDM) - This is the most common type of 3D printer and is often used for prototyping and small-scale production. It works by heating a filament of plastic and extruding it layer by layer to create the object. 
  • Stereolithography (SLA) - This type of 3D printer uses a laser to cure liquid resin, layer by layer, to create the object. It is often used for creating highly detailed and precise parts. 
  • Selective Laser Sintering (SLS) - This type of 3D printer uses a laser to fuse together powders of materials such as metal, plastic, or ceramic to create the object. It is often used for creating highly detailed and precise parts, and for small-scale production. 
  • Digital Light Processing (DLP) - This type of 3D printer uses a projector to cure liquid resin, layer by layer, to create the object. It is often used for creating highly detailed and precise parts. 
  • Metal 3D printers - This type of 3D printer can print in metal, such as titanium and steel, making it great for aerospace and industrial applications. 

Importance of 3D printers:

3D printing has the potential to revolutionize the way we design and create products. It allows for faster, more efficient, and cost-effective product development, as well as the ability to create unique, custom designs. It also enables on-demand manufacturing, reducing the need for inventory and warehousing. Additionally, it has opened up new possibilities in fields such as healthcare, where 3D printing is being used to create prosthetic limbs and surgical models, and in architecture, where 3D printing is being used to create full-scale building components. 

How does a 3D printer work?

3D printers work by laying down successive layers of material to create a three-dimensional object. The process starts with a digital model of the object, which is then sliced into layers by 3D printing software. The 3D printer then reads these slices and lays down the appropriate amount of material layer by layer, creating the final object. The process can take anywhere from a few minutes to several days, depending on the size and complexity of the object. 

What can you 3D print?

3-dimensional (3D) printing technology has the capability to manufacture a vast array of items, ranging from simple playthings and statuettes to intricate mechanical components, prosthetic appendages, and even edifices. The process entails using various materials, such as plastics, metals, ceramics, and even comestibles, to create the desired products. 


Among the most popular uses of 3D printing are: 


  • Prototype fabrication and product advancement: 3D printing enables the swift and effortless construction of prototypes, which can significantly reduce time and expenses in the process of product development.  
  • Personalized and customized product production: 3D printing facilitates the production of one-of-a-kind and tailored goods, such as customized trinkets and smartphone casings. 
  • Manufacturing: 3D printing is increasingly being used in small-scale production and on-demand manufacturing, reducing the need for inventory and warehousing. 
  • Healthcare: 3D printing is being used in the creation of prosthetic limbs, dental implants, and even human tissue. 
  • Architecture: 3D printing is being used to create full-scale building components and even entire buildings. 


Intro to 3D printing software:

3D printing software is used to create digital models of the objects that will be printed. It can also be used to slice the models into layers that the 3D printer can understand. There is a variety of 3D printing software available, including open-source and commercial options. Some popular 3D printing software includes: 

  • Cura 
  • PrusaSlicer 
  • MatterControl 
  • Ultimaker Cura 



Step-by-step 3D printing process:

The 3D printing process typically involves the following steps: 

  • Create a digital model of the object using 3D modeling software. 
  • Prepare the model for printing by slicing it into layers using 3D printing software. 
  • Send the sliced model to the 3D printer via USB or over the network. 
  • Set up the 3D printer and load the appropriate material. 
  • Start the print process and wait for the object to be printed. 
  • Once the print is complete, remove the object from the printer and clean up any excess material. 

How much do 3D printers cost:

3D printers can vary greatly in cost, depending on their capabilities and the materials they can use. A basic FDM 3D printer can cost as little as a few thousand Rupees, while a high-end industrial 3D printer can cost several hundred thousand Rupees. In India, the cost of a 3D printer can range from 20,000 INR to 20,00,000 INR. 


Some examples of 3D printing include: 

  • An aerospace company uses a metal 3D printer to create complex engine parts. 
  • A dental lab using a 3D printer to create custom dental implants. 
  • A fashion designer using a 3D printer to create unique jewelry designs. 
  • An architectural firm using a 3D printer to create full-scale building components. 
  • A medical facility uses a 3D printer to create a customized prosthetic limb for a patient. 

The picture below shows aerospace components that are created by a 3D printer and it is in use for commercial applications. The raw materials used are accordingly chosen to give structural rigidity as required. 


3D printing is a rapidly evolving technology that has the potential to revolutionize the way we design and create products. It is becoming increasingly accessible to consumers and small businesses and is being used in a wide range of applications, from prototyping and product development to healthcare and architecture. With the growth of this technology, the possibilities of 3D printing are endless and the future of 3D printing looks promising. So get a 3d printer and start 3d printing.

Frequently Asked Questions

1. What is 3D printing and how does it work?

3D printing is a method that utilizes additive manufacturing technology to generate three-dimensional objects from a digital file. The procedure involves first creating a 3D blueprint with computer-aided design (CAD) software. After that, the 3D printer reads the digital file and forms the object by laying down successive layers of material. The materials used in the process can vary and commonly include plastics, metals, and ceramics. This technique is referred to as additive manufacturing because the final object is produced by adding material layer by layer until it is complete.

2. What is 3D printing used for?

3D printing is a highly adaptable technology with numerous applications. Some of the most prevalent uses include creating prosthetics, hearing aids, and other medical devices. It is also used for rapid prototyping and manufacturing. The technology is beneficial in creating models of organs, and other internal structures for medical research and education. Moreover, it is used for creating sculptures and other art pieces, customized products like jewelry or phone cases, and replacement parts for machinery and equipment.

3. How do 3D printers work exactly?

3D printers utilize a process known as additive manufacturing, which involves creating a design through computer-aided design (CAD). The printer then dispenses a material, such as molten plastic, layer by layer, to create a three-dimensional object from scratch. This is achieved using either a hot nozzle or precision tool. The object is built from the bottom up, slice by slice until the desired shape is formed.

4. What is the future of 3D printing?

The 3D printing industry is anticipated to become more dynamic and robust in the future, with a more comprehensive ecosystem offering solutions ranging from design to materials and post-processing. Although 3D printing was initially perceived as a technology for consumers, it has since transformed into a much more sophisticated field. Experts in additive manufacturing are optimistic about reporting on 3D printing for another decade. Forbes has also recognized ten intriguing ways that 3D printing will be utilized in the future.
