3D Printing Technology Guide

3D Printing is now one of the fastest-growing fields due to its uncountable advantages and unimaginable potentials. From developing prototypes to creating replacement parts, from reconstructing fossils to designing customized consumer products, the 3D printing technology uses are expanding each day.

3D printing technology is now playing a significant role in nearly all major industries across the globe, and its impact will keep on growing as more and more people and industries gain access to the amazing 3D printing technology.

What are 3D printers?

 3D printers

3D printers use computer-aided design (CAD) to produce three-dimensional objects. The 3D printed items are made from a variety of materials, including powders, to molten plastic.

Also referred to as – “additive manufacturing,” 3D Printing involves layers of different materials to produce a three-dimensional object. The commonly used layering materials include composites, plastic, and bio-materials; these materials are used to create items of different shapes, sizes, colors, and rigidity.

These printers act similar to 2D inkjet printers and used a layering method to produce the desired design and object. 3D printers create objects from the ground up and stack layers on top of each other until the desired object shape is achieved.

One of the biggest reasons behind these printers’ widespread popularity is the extreme versatility and flexibility of creating various customized objects. From printing consumer objects from plastic-like sunglasses, phone cases, bike handles to utilizing carbon fiber and metallic powders to print extremely strong industrial products – 3D printers have endless possibilities.

How Do 3D Printers Work?

As mentioned above, 3D printers are from the additive manufacturing family, and they utilize a similar printing method as the traditional inkjet printers. 3D Printing is a revolutionary technology that uses a combo of hi-tech software, powder-like manufacturing materials, and precision tools to produce 3D objects from scratch.

Unlike traditional office printers, 3D printers use computer-aided design (CAD) to produce three-dimensional objects. The 3D printed items are made from a variety of materials, including powders, to molten plastic.

The process of 3D Printing begins with making a digital 3D model, which you can develop of download from a 3D model repository. If you are creating it yourself, you will use a 3D scanner, haptic device, app, code, or a 3D modeling software.

3D Modeling Software

There are various 3D modeling software tools that you can use, including software designed especially for industrial use that costs thousands of dollars per year. Nonetheless, there are also open-source software that are available for free.

If you are a new to 3D printing technology and wish to dip your toes in the world of 3D Printing, then we recommend free software that works in your browser. You can find beginner-friendly options that come with instructions and tips to help you along.

Once the three-dimensional model is finished, you will prepare the file to send it to the 3D printer; this process is called slicing.


Slicing is the process of dividing a 3D model into thin horizontal layers using a slicing software. After your file is sliced, it is ready to be sent to the 3D printer through the internet, USB, or SD. The model is then printed as per the sliced layers.

A built-in slicer is also available in some 3D printers in which you can input raw .stl, .obj, or even CAD files.

The Process Of 3D Printing

After the modeling and slicing of a 3D object is finished, the 3D printer can finally take over. In the direct 3D printing process, the printer behaves similarly to a standard inkjet printer, with a nozzle moving back and forth while depositing a wax or plastic-like polymer layer by layer, waiting for each layer to dry before adding the next one. It simply layers hundreds or thousands of two-dimensional prints on top of each other to create a three-dimensional item.

Materials For 3D Printing

A printer employs a variety of materials in order to duplicate an object to the maximum of its ability. Here are a couple of such examples:

Acrylonitrile Butadiene Styrene (ABS)

Plastic that is simple to mold and challenging to break. The same stuff that LEGOs are composed of.

Carbon Fiber Filaments

Carbon fiber is utilized to make products that must be both robust and lightweight.

Conductive Filaments

These printable materials are currently in the testing stage but can be used to create electric circuits without wires. This is a material that can be used in wearable technologies.

Flexible Filaments

Flexible filaments create prints that are both pliable and durable. These materials can be used to print on a variety of items ranging from wristwatches to smartphone covers.

Metal Filament

Metal filaments are created by combining finely ground metals with polymer glue. To achieve a metal object’s authentic look and feel, it can be made of steel, brass, bronze, or copper.

Wood Filament

These filaments are made of finely ground powdered wood and polymer glue. These are undoubtedly utilized to print wooden-looking items, plus they can appear lighter or darker depending on the printer’s temperature.

The 3D printing process can take a few hours for straightforward prints, such as a box or a sphere, to days or weeks for larger, more complicated projects, such as a full-sized house.

Processes And Techniques For 3D Printing

Various sorts of 3D printers are available based on the scope, size, and detail of a task. The way an object is produced will vary slightly depending on the type of printer used.

Fused Deposition Modeling (FDM)

FDM is most likely the most popular type of 3D Printing. It’s pretty helpful in making plastic prototypes and models.

Stereolithography (SLA) Technology 

SLA is a type of rapid prototyping printing that works best for Printing in fine detail. The printer creates the things in hours using an ultraviolet laser.

Digital Light Processing (DLP) 

DLP is among the most traditional types of 3D Printing. Since the layers dry in seconds, DLP printing can produce prints at a faster rate than SLA printing.

Continuous Liquid Interface Production (CLIP) 

CLIP is one of the quicker Vat Photopolymerisation techniques. CLIP technology is used to project a succession of UV pictures across a cross-section of an entirely 3D-printed item, resulting in a perfectly controlled curing process. After that, the part is baked in an oven or thermal bath, which causes multiple chemical processes that allow the piece to solidify.

Material Jetting 

Material jetting layers droplets of printing material using a nozzle with a small diameter to create a platform that is hardened by UV radiation.

Binder Jetting 

Binder Jetting makes use of a powder base material that is evenly coated with a liquid binder that is delivered through jet nozzles to serve as a glue for the powder particles.

Fused Deposition Modeling (FDM)

Fused filament fabrication (FDM), or Fused Filament Fabrication (FFF), unwinds a plastic filament from a spool and directs it through a heated nozzle in horizontal and vertical directions, producing the object as the molten material hardens.

Selective Laser Sintering (SLS) 

SLS is a kind of Powder Bed Fusion that employs a high-powered laser to fuse microscopic powder particles together to create a 3-D shape. The laser scans and selectively connects each layer on a powder bed before dropping the powder bed by one thickness, then repeating the process till completion.

Multi-Jet Fusion (MJF) 

MJF, another type of Powder Bed Fusion, employs a sweeping arm to drop powder with an arm equipped with inkjet to apply binder on top selectively. The detailing agent is then applied precisely around the detailing agent. Lastly, thermal energy is used to initiate a chemical reaction. This identical procedure is used in Direct Metal Laser Sintering (DMLS) but using metal powder.

Sheet Lamination

Sheet lamination uses external force to bind material in sheets and layered ultrasonic welding to join them. The sheets are next machined on a CNC machine to make the shape of the product.

Directed Energy Deposition

Directed Energy Deposition (DED) is an industrial metal technique that uses a 3D printing device attached to a robotic multi-axis arm with a nozzle for dispensing metal powder. The powder is put onto a surface and an energy source, melting and solidifying the substance.
