3D printing is an additive process in which three-dimensional objects are made from digital files. It entails laying down a series of layers of material until the object is created. This innovative production process uses materials like plastic, ceramic, metal, or any other material to make complex shapes.
The relative ease with which we can now produce literally any three-dimensional object by generating thin layers over and over to produce the final product is amazing.
What is 3D Printing?
3D printing also referred to as Additive Manufacturing (AM) can help you create a design of an object using software and then the 3D printer creates the object by adding layer upon layer of material until the shape of the object is formed.
The final object can be made using any number of printing materials that may include plastics, metals, powders, filaments and paper.
The benefits derived from 3D printing include short production runs; easy and quick prototyping; quick customizability and adaptation; the ability to create complex shapes; cost-effectiveness; and reduced waste.
It has revolutionized production systems thanks to the fact that it prints parts in layers. This makes it possible to create complex objects that have internal structures or subassemblies in one single run which was previously difficult to do using traditional means of production.
Another innovation with this means of production is that material is added rather than subtracted. Here raw materials are added to build an object rather than removing or scrapping material.
This enables mass manufacturing runs without the need for individual tooling or hand-crafting. This in turn helps conserve raw materials and creates an efficient design and production process.
The worldwide 3D printing industry was valued at around 12.6 billion dollars in 2020. It is expected to grow at an annual rate of some 17% between 2020 and 2023. 3D printing technology is truly innovative and has emerged as a versatile technology offering a wide range of applications adopted by a wide range of industries.
The Benefits of 3D Printing
3D printing stands out for its ability to streamline the design and manufacturing process, offering benefits such as:

3D Printing Technologies for the Best 3D Printed Designs
Once you’ve created your design, it’s time to print! You’ll find a huge variety of 3D manufacturing methods to choose from. The method you choose will depend on what material you’d like to print on and what industry the product is being designed for.
Here are some of the leading examples of 3D printing methods and their uses.
Fused deposition modeling (FDM)
Considered among the best-known form of additive manufacturing it works by pushing a filament of solid plastic or other materials into a hot-end that then extrudes a thin stream of molten material in layers to build up the desired 3D piece.
Here the print head’s movement is controlled one layer at a time to define the printed shape.
This process is used for prototyping and rapid manufacturing in industries like automotive, manufacturing, medicine, and aeronautics. It mostly uses plastic material for 3D printing and polymers such as ABS, PolyCarbonate (PC), Polylactic acid (PLA), Polyethylene terephthalate (PETG) and others.
Stereolithography (SLA)
Stereolithography (SLA) or resin printing is a form of 3D printing layer by layer using liquid plastic resin that is hardened using light to create a chemical reaction for it to form hardened plastic.
It can be used to create prototypes , models, components and computer hardware.
This process helps create fine features and smooth surface finishes.
Its application includes manufacturing, printing custom tools, molds, jewelry, medicine as well as many other applications. Though stereolithography is fast and can produce almost any design, it can however be expensive.
Material jetting (Polyjet)
This process works in a similar manner to inkjet printing but rather than laying down ink on a page, it deposits layers of liquid material from one or more print heads.
It helps produce highly accurate, full-color visual prototypes. Its applications can be used in teaching, automotive, medicine, making molds and casting patterns.
Even though it is a precision process, it is one of the most expensive 3D printing methods with parts not being sturdy and degrading over time. This process allows for the creation of electronic devices as well.
Selective Laser Melting and Selective Laser Sintering (SLM/SLS)
Selective Laser Melting ( SLM) technique uses a high power-density laser to melt and fuse metallic powders together. It mostly uses a variety of metals including titanium, copper, nickel, aluminum and cobalt for industries such as medical, automotive, aeronautics, and even jewelry.
In this process you can produce parts with excellent physical properties that are often stronger than the conventional metal and good surface finishes. This comes in handy in prototyping and tooling as well.
Binder Jetting
Binder jetting process entails depositing a thin layer of powdered material such as a metal, polymer resin or ceramic, onto the build platform. It then drops adhesive which is deposited by a print head to bind the particles together.
Binder Jetting is used in various applications, including the creation of full-color prototypes, molds, and low-cost 3D printed metal parts.
The common materials used in this process are ceramic and metals. It can also be used in industrial applications, dental and medical devices, aerospace, part casting, and more.
Fused filament fabrication (FFF)
Fused filament fabrication (FFF), is a 3D printing process that uses a continuous filament of a thermoplastic material. The filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work.
This process is used in applications that include prototyping and rapid manufacturing in aerospace, medicine, machine design, and even food.
This process helps fuse a large selection of materials, including thermoplastics, wood and metal-infused thermoplastics, and even food. This is considered among the least expensive 3D printer technology as it uses inexpensive materials.
It is also easy to switch materials and lets you print using multiple different materials with a fast printing process.
Electronic beam melting (EBM)
In Electron Beam Melting (EBM) the raw metal powder or wire material is placed under a vacuum and fused together from heating generated by an electron beam. The hot process helps to produce parts with no residual stress and the vacuum ensures a clean and controlled environment
This technique results in the creation of high-density products as it utilizes the entire metal powder. As a result, it is predominantly used in the medical, aeronautics, and automotive industries.
Digital Light Processing (DLP)
Digital Light Processing (DLP ) is similar to stereolithography in that it works with photopolymers. The major difference is the light source. The DLP technology uses a more conventional light source, such as an arc lamp with a liquid crystal display panel.
This is then applied to the entire surface of the vat of photopolymer resin in a single pass, generally making it faster than stereolithography. As a result, it produces highly accurate 3D printed parts with excellent resolution that are ideal for prototype production.
Environmental Implications of 3D Printing
While 3D printing offers a more sustainable alternative to traditional manufacturing processes by reducing waste, its environmental impact is nuanced. The energy consumption of 3D printers can be high, especially for metal printing processes, and the materials used, such as certain plastics, may not always be eco-friendly.
However, the technology also presents opportunities for using recycled materials and developing new, more sustainable printing materials. As the technology matures, focusing on reducing its carbon footprint and finding greener alternatives will be crucial for its sustainable development.
