3D Printing: Everything You Need To Know (Complete Guide)

Are you in shock to know that even the most talented artists struggle to represent what real objects look like in 3D printing? Now you must be thinking that it is easy to get a good idea by looking at the picture or sketch.

But if you are involved in a business that demands developing fresh products to show to the customer then what would be best that a model you can feel, hold and touch? The only problem is that it takes ages to make a mode by hand as well as machines but with 3D printing, you can create the same object layer by layer in less time and cost. 

Now the question arises: What is 3D printing? How does a 3D printer work? Well, 3D printing is a method of making a three-dimensional object step by step by using a computer-generated design. 3D printing enables you to create complex shapes utilizing less material than the traditional methods. Wait, don’t take 3D printers like the one you see in movies. They are similar to the 2D inkjet printer and creates an object layer by layer.

These printers are considered to have superb flexibility in printing. And they also use plastics to print materials such as sunglasses, bike handles, phone cases by using a plastic powder or hybrid rubber. Not only this, but some 3D printers are also capable of printing using metallic powders and carbon fiber, and metallic powders for sturdy industrial products.

Brief Into 3D Printers

Brief Into 3D Printers

3D printers create 3D models and products using various types of materials such as plastic, powder by using CAD (computer-aided design). 3D printers are not different from 2D printers as the only fact which distinguishes them is the layering technology for creating objects. As mentioned above, these printers are super flexible in printing and using numerous materials.

3D printers are accurate and fast which is why they are expanding their foothold. Also, they are gradually becoming a powerful tool for the manufacturing industry. One can easily perform rapid prototyping via 3 printers which help in replacing the million dollars cost in research.

You can analyze their importance for the future by the fact that now companies are employing 3D printers to create prototypes instantly. According to numerous companies, the technology of the 3D printers is at least 8 to 9 times faster in the process of prototyping and costs 6 times less than the R&D process. These printers are acquiring every sector as they are used for multiple purposes such as printing finished objects.

3D printers are virtually acquiring every industry. Not only prototyping but many 3D printers are also used for printing finished objects. If we see the construction industry then homes are completely printed using futuristic printing. Looking at the present situation, the healthcare industry uses 3D printers technology to counter the Covid pandemic. It plays a vital role in the science and robotic field. 3D printing is a gamechanger in every industry.

Let’s Learn How Does 3D Printing Work

Numerous software combines to form 3D printing that uses materials such as plastic, powder, carbon fibers, etc to make a 3D product. There are three main processes through which 3D printing functions.

3D Modeling Software

3D Modeling Software (3D printing)

This is the foremost step that brings precision and accuracy to your prints. But some designs are a little difficult as well as detailed and here we use CAD software. It takes care of the tiniest detail and creates the product with utmost precision. This software is a powerful as well as game-changer in the industries such as dentistry.

This software creates teeth aligners. Not only this, but the space industry also uses this unique modeling software to design spaceships, rockets, and other parts.

Slicing the Model

Slicing the Model

After creating the product/model, there comes the part to “slice” it. The “Slice” means creating layers of a model consecutively to form a final object with accuracy and perfection. Slicing software does scanning of each layer of the 3d model and guides your printer on creating those consecutive layers.

Slicers help the printers in guiding them where to fill an object. Filling means giving lattices and internal columns for smooth shaping and powerful solid objects. On completion of the slicing model, the 3D printer will receive it to carry forward the process of printing.

The Process of 3D Printing 

The Process of 3D Printing 

After completing both modeling and slicing, the 3D printer will then conclude the task. Note that, the 3D printer works similarly to an inkjet printer. The nozzles move backward and forward while ejecting simultaneously a plastic-type polymer wax. After that, it waits for the layers to get dry and repeat the similar steps layer by layer.

Numerous 2D prints come together to form an accurate 3D object. Many materials are used for it such as:

  • Acrylonitrile Butadiene Styrene: LEGOs are made up of ABS because this plastic can’t break easily and you can shape it conveniently.
  • Conductive Filaments: Used in wearable technology to print wireless electric circuits.
  • Carbon Fiber Filaments: Used to make strong but lightweight products like carbon fibers.
  • Metal Filament: It is a combination of polymer glue and ground metals. Also, they are present in steel, copper, brass, and bronze to enhance the look and outer structure of a metal object.
  • Flexible Filaments: It is rigid and tough but bendable. This feature makes it demanded highly in printing wristwatches and phone covers.
  • Wood Filament: It is a combination of polymer glue mixed with groundwood powder to print wooden-looking models. Here the print’s contrast depends on the printer’s temperature.

Depending on the size of the print (Simple box printing, ball, or home prints), the 3D printing process can take time from hours to weeks.

  • SLA (Stereolithography): It is mainly for detailed printing or fast intricate prototyping. This technology makes use of ultraviolet lasers for crafting objects in hours. 

SLA (Stereolithography)

  • DLP (Digital Light Processing): It is the oldest form of 3D printing that uses lamps for making prints fastly making ink dry faster between layers.

DLP (Digital Light Processing)

  • FDM (Fused Deposition Modeling): It is 3D printing used for creating plastic objects for manufacturing designs.

Examples of 3D Printing 

We use 3D printing in many spheres of our lives and it has become an important part of almost every industry. Let’s check out some examples of things to 3D print:

  • Footwear, furniture, eyewear, and other products. 
  • Dental equipment. 
  • Manufacturing tools, as well as, designs of industrial products. 
  • Architectural scale prototypes.
  • Prosthetic.
  • Fossils reconstruction.
  • Maquettes.
  • Reconstruction of forensic pathology evidence.
  • Old artifacts replicating models.
  • Movies props.

Aerospace technology is using 3D printing since 1980. This industry uses 3D printing in numerous ways different ways. From creating 3D printed aircraft and space shuttles to cobalt-chrome fuel nozzles, the technology never fails to surprise us. The rockets designed are custom-printed via a proprietary alloy metal. And it helps in decreasing the assembly time and increasing the payload volume. 

Aerospace parts contain thin walls, internal channels, difficult curved surfaces for conformal cooling. The technology of 3D printing design helps in producing complex and lightweight models. With maximum stability and high strength, it allows the integration of various parts into one component. This can lead to:

  • Waste Reduction.
  • Costs Reduction.
  • Increased Consistency.
  • Faster Production.
  • Better Surface Finishing.
