3D printing tutorial

3D printing is a technique for layering a three-proportional structure that uses a computer-generated template. 3D printing is an additive method that involves building up layers of material to make a three-dimensional object. Subtractive manufacturing techniques, in which we cut a model from big blocks of material, are the polar opposite of additive manufacturing. As a consequence, there is less waste from 3D printing. 3D printing is also ideal for rapid prototyping because it allows for the production of complex, custom objects. 

3D printing is a very satisfying and enjoyable hobby. It is a very pleasant feeling to begin a project with an idea and finishing it with a finished product in your lap. Thanks to the hobby’s often steep and continuous learning curve, it can be a very boring pastime.  

The technology of 3D printing

Sintering, freezing, and stereolithography are the three main methods of 3D printing technology. Sintering is a technique for creating high-resolution objects in sintering; we heat the object but prevent it from melting. For direct metal laser sintering, metal powder is used; for selective laser sintering, thermoplastic powders are used.

Direct energy, electron beam melting, powder bed fusion, and disposing of are 3D printing melting techniques that use lasers, electric sparks, or electron beams to melt materials together to print artifacts. 

Photopolymerization is used in stereolithography to produce components. This technique uses the right light origin to selectively communicate to substance, curing and solidifying a thin layer object’s cross-section.

Kinds of 3D printing

3D printing can be classified into the following categories:

• Binder Jetting

• Accumulation of Quick Power

• Diffusion of Components

• Bouncing of Products

• Fusion of Powder Beds

• Laminating a Sheet 

• Polymerization of VAT

Basic Tips for 3D printing

Here are the tips for better 3D printing techniques: 


It’s important to stay secure when working with 3D printers, and there are, though, a few things to bear in mind as you continue your journey into the world of 3D printing.

Nozzle’s temperature:

The temperature of the nozzle, regardless of how many there are, has a major effect on the print’s composition. If the nozzle gets too hot, filament strings will form between the bits. High temperatures allow the earlier layers of a tall piece to melt, allowing the material to deform. With a centimeter block on the converse direction for taller prints, make a plate. It prevents the hot nozzle from being printed and lets it cool. Slicer systems typically use a wall or drip shield frame, as well as filament strings within structures.  

Find the Right Temperature for Your Bed:

Controlling the temperature of the build plate (or bed) aids print adhesion. Each layer of the model shrinks as it cools as it prints. As a result, each sheet above the bed shrinks, causing the print’s edges to pull away from the create plate. The model will evolve if the bed temperature is too high. This means that you can lower the bed condition slightly for the next print. 

Different plates and their effects:

On the bottom of the print, various create plates produce different textures. Glass, PEI, or Kempton tape leaves a flat surface on the bed. To create a gloss coating, stick-on polycarbonate paper may be used without leaving gaps or abnormalities, using only enough spray on the top to stick to the print. It’s also impossible to erase the print if there’s too much glue or spray on it. Forcing it off may destroy the print or, if applied with enough force, crack or warp the plate for the test to see which solution fits your setup well while still leaving a finish that complements the print. 

Printer modifications and servicing:

Every 3D printer has its unique characteristics and flaws that need to be addressed to better print quality. Some are low-cost printers that benefit from an upgrade. This post goes into a couple of these updates. It also includes suggestions for identifying and correcting the flaws of other low-cost printers. Cleaning and greasing the bars according to vendor instructions is one of many minor measures in optimizing your printer. If the printer’s Z-axis has two stepper motors, make sure the frames are the same height on both sides. Check continuously to see if there is some flutter in the picture. Check the manufacturer’s website for new firmware to ensure the bolts are tight and all 90-degree angles are square.

Caring of Filament:

Many filaments like water and absorb it from the air. Exposed filament absorbs moisture and causes problems, particularly ABS, nylon, and flexible materials. Through extrusion, the filament stretches as the water bubbles out of the plastic and in it turns to steam. It clicks or crackles, and a closer examination shows what seems to be smoke as the filament goes through the nozzle. The key thing, though, is that when the print is out, it may seem shabby. With regular turnover between applications, hold spools in plastic bins. In certain cases, the filament spool may be dried in the oven at very low temperatures for a few hours. Making your heated bin is an enjoyable process and easy and feeds into your 3D printer.


It’s impossible to speak about 3D printing performance without considering slicers. A slicer turns a 3D picture into printer G-code instructions. There are several choices to choose from, the bulk of which are open. Check to see whether a “perfect” or “hyper” quality setting is available if the print isn’t as “neat” as it should be. The results can be worth the wait, although the printing will take longer. If a few prints come out bumpy, don’t go to a different slicer. Tweak one setting at a time, investigate the problem thoroughly. Try printing it again to see how it works.


3D printers operate by extruding molten filament that adheres to the substrate under it. The slicer can attempt to bridge the overhang if there is no layer beneath it to bind with. Sagging or total loss of the print will occur if the bridge is too long. Knowing how and where to use supports requires both research and practice. 

Closing the Gaps:

Small holes may appear on the top and sides of precision-printed products. By steadily increasing how the perimeter overlaps the infill, quality issues on the sides may be alleviated. Check to see how the print fills the space after each small update. If the infill rate is too fast, the molded filament cannot stick with the perimeter since the nozzle isn’t able to extend as much for the molded filament to form a link. This can cause other problems, decrease the speed of print, but not so much. Examine the amount of filament removed as well. Make slight adjustments when changing this amount. For each update, increase the rate by a hundredth of a percent (.01), and then print a test print. 

Prevent from Dragging:

Ringing or flickering along corners or print elements degrades image consistency. Movements from the extruder’s action create these untidy lines. Reduce the print speed to solve the query. However, ensure that the extruder moves sufficiently to keep the printed region from overheating and causing other consistency issues.


A sharp drill knife or sandpaper may be used to remove supports or minor defects, particularly if painting or polishing is necessary. Acetone vapor treatment works well on certain plastics, such as ABS. The effect is a gleaming finish, but as the plastic dissolves, which is a chemical change, it weakens the mold. To create a tarnished look, composite plastics, with sanding and a special coating such as brass or copper-infused plastics, are reinforced.

Keep it clean:

Pay careful attention to the construct surface of your printer. The layer that holds your print as it is being printed is known as the construct board. It is undoubtedly one of the most critical elements for effective 3D printing, but it is still the most underestimated. Holding it clean and free of damage can improve the 3D printing experience dramatically.
