How Does 3D Printing Work?

3D Printing is regarded as a very versatile method to produce and comprehend rapid prototyping. Since recent years, many breakthroughs in the industrial sector have resulted in increased demand for 3D Printing. More precisely 3D printing involves additive manufacturing technology which is helpful in the creation of an object model in layers. Additive manufacturing is called with various other terms like stereolithography and 3D layering.


The 3D Printing Process starts with making a graphic representation of the object model which is needed to be printed. These are designed by using a CAD software package in the very labor-intensive step of the 3D printing process. CAD programs include TinkerCAD, Sketchup, Fusion360, and more.

For complex product models, extensive testing is done in simulation to make sure that all potential defects are eliminated from the final product. If the object to be printed is decorative then in this case this step holds less face value. One of the major benefits of 3D printing includes rapid prototyping of any object you so ever can think of your eyes closed and fingers crossed. CNC milling and molding constitute the traditional means of manufacturing methods relating to 3D printing. After 3D designing, the next step involves digital slicing of the model to be printed layer after layer. The step is best known to all 3D printers as the 3D printer is unable to conceptualize a 3D model just like humans can perceive a certain object through mental cognition.


The slicing process allows the slicing of the object model into multiple layers. The design of the individual layer is then sent into the printer from the head to start printing or in an order of lay down. The slicing process is done via specially designed slicer programs such as Astroprint and CreaftWare.


These software tools also handle the ‘fill’ of the model by creating a lattice-like structure within the solid model for increased stability ratio. Such things also happen to take place in the area where 3D printers excel. These specialized and care-sensitive tools allow easy printing of stronger materials that have less density level. This process can be achieved by the addition of pockets of air within the inner section of the final product.


Slicer software adds columns wherever they are required due to the reason that plastic can’t be laid in thin air and columns help retain the gaps between the printer to the bridge. All columns are afterward removed from the scene if required so. After performing its function slicer program sends the data to the printer for final processing. From here, the later processing is done via a 3D printer until completion. The object model is then printed out exactly as intended with specific instructions and requirements in a perfectly orderly manner. Remember that the output of any type of printer employed for the purpose may vary accordingly to the advancement of technology.




Direct 3D Printing involves extensive use of technology quite similar to inkjet technology. In such technology, the nozzle can be moved forth and back position and can easily dispense thick waxes of polymers (plastic). Such polymers after some time solidify into forming a new cross-section of the 3D object model in the process. In Multi-jet Modeling dozens of jets work counteractively and are best to model objects at a relatively higher speed. In Binder 3D Printing the nozzle of the inkjet leaves a dry powder with liquid glue (binder). Such a material binds different layers of the model together firmly and effectively. Binder 3D Printer makes at least two passes for each layer type. The first one is helpful in deposited equally a thin fine coat of powder and the latter pass make use of the nozzles to spread the binder. Also, Photopolymerization involves dropping off plastic in liquid form which is then exposed to a laser beam UV light, and conversion of the liquid phase to solid phase takes place during the course.


Another efficient 3D printer named Sintering makes use of both melting and fusion processes to bind different successive layers of the model.


The Process


The process may vary for objects ranging from simple to complex but even different types of 3D printers operate on the same principle steps. The process of 3D printing is simple and easy if you care to follow the below-mentioned steps cum rules in the given orderly manner:


Step 1: Have a reference or think of an idea according to which specific CAD software is going to be used for 3D printing needs.


Step 2: All CAD drawings must be converted to an STL (Standard Tessellation Language) format. Other formats like ObjDF and ZPR are also accessible to most 3D printers.


Step 3:  The STL file format can be then transferred to computers which give orders of functionality to 3D printers and in this way the user can identify and design the size and other specifications of printing a 3D Model successfully.


Step 4: The 3D printer itself is an incredible setup. Every machine type includes its operational requirements like refilling polymers, consumables, and binders, etc.


Step 5: Just begin with the machine setup and wait until the build is complete. The machine keeps a check during the process to ensure every step is in perfect order and no errors are brought up.


Step 6: The printed object can be easily removed from the 3D machine. 


Step 7: the last step involves a post-processing arrangement. Just like brushing off the remaining powder and washing through the printed object to rinse away all the water-soluble particles.


What can a 3D printer make?


As we have discussed in the earlier opening section of the blog, 3D printers are best known to be versatile, 3D printers can create anything in this world theoretically speaking. There are many different kinds of materials that can replace ink for printing. For bigger and heavier objects let us think of a house, all you need is to print in separate individual parts or employ a very large 3D printer to print the object at a commercial scale.


Different examples of 3D printing objects are mentioned below:


Prosthetic limbs

Musical instruments 


Movie props

Homes and other buildings 


Liquid Structures


Glass Products


Acrylic objects

Medical models and other devices
