3D printing, also called additive manufacturing, is often defined as the construction of a three-dimensional object from a CAD model or a digital 3D model. The term “3D printing” is often explained as a spread of processes during which materials are deposited, solidified with computer control to present a three-dimensional object, with more material being added together typically layer by layer.

Looking at current scenarios 3D printing or additive manufacturing has been used widely for manufacturing, medical, industry etc. which facilitate 3D printing to become successful economical technology. The earliest application of 3D printing was on the toolroom end of the manufacturing spectrum.


3D printers are available and are a neighborhood of the additive manufacturing family and use familiar methods to a standard inkjet printer- albeit in 3D. It takes a mixture of top-of-the-line software, powder-like materials and precision tools to make a three-dimensional object from scratch.

The various steps include :

3D Modeling Software:Modeling helps printers to form the merchandise come right down to the tiniest detail. The 3D modeling software ensures precision designs is why 3D printing is being hailed as a real and important changer in many industries.

Slicing the Model: Engineers are required to slice the model into layers to assist the printer to make the ultimate product. Slicing software takes scans of every layer of a model and can tell the printer the way to move so as to recreate that layer.

The 3D Printing Process: The printer acts an equivalent as a standard inkjet printer within the 3D printing , where a nozzle moves back-and-forth while dispensing a wax or plastic-like polymer layer-by-layer, expecting that layer to dry, then adding a subsequent level.

There are various types of 3D printing depending on size, shape and also time consumed in making one depends on these factors. 


  1. Fast Design and Production, helps design and print faster also production rate saves time. 
  2. Minimises Waste, little wastage compared to traditional methods. 
  3. Cost Effective, requires lesser products, machine cost can be saved by outsourcing the project. 
  4. Easy To Use, easily accessible by everyone. 
  5. Environmental Friendly, Fuel efficient and less wastage. 
  6. Flexible Design, helps design and print complex designs. 


In the construction world , 3D printing is  used to create construction components or to print even entire buildings. Construction is well-accustomed to 3D printing as much of the information necessary to create an product will exist as a result of the design process, and the industry is already experienced in computer aided manufacturing.3d printing  is not a new technology, followed since the 1980s. Making a three-dimensional model, or prototype, from a computer made design by adding successive layers of material is now standard practice in many industries, ranging from aerospace and architecture to medicine and high-end manufacturing.

3D printing encompasses many sorts of technologies and materials as 3D printing is getting used in most industries you’ll consider . It’s important to ascertain it as a cluster of diverse industries with a myriad of various applications.
A few examples:
– consumer products (eyewear, footwear, design, furniture)
– industrial products (manufacturing tools, prototypes, functional end-use parts)
– dental products
– prosthetics
– architectural scale models & maquettes
– reconstructing fossils
– replicating ancient artefacts
– reconstructing evidence in forensic pathology
– movie props
