How 3D Printing Works

3D printing, also known as additive manufacturing, is a transformative technology that turns digital designs into three-dimensional objects. This innovative process is achieved by building objects layer by layer, using various materials such as plastics, resins, or metals.

The journey of a 3D printed object begins with a digital 3D model, which can be created using computer-aided design (CAD) software or obtained from online platforms. This digital model serves as the blueprint for the 3D printer, guiding it on how to construct the physical object.

Once the digital model is ready, it is sliced into thin layers, each representing a cross-section of the final object. These layers typically range from 0.05mm to several millimeters in thickness, depending on the desired level of detail and the capabilities of the 3D printer.

The 3D printer then interprets each layer and begins the printing process. There are several different technologies and techniques employed in 3D printing, including:

Fused Deposition Modeling (FDM): This is one of the most common 3D printing techniques. It involves feeding a continuous filament of plastic material, such as PLA or ABS, into a heated nozzle. The nozzle melts the filament, which is then extruded layer by layer onto the build plate. As the material cools, it solidifies, forming the object.

Stereolithography (SLA): SLA utilizes a liquid resin that is cured by a UV light source, selectively solidifying the resin layer by layer. The build platform gradually moves upwards as each layer is cured, resulting in a fully formed object once the printing is complete.

Selective Laser Sintering (SLS): In SLS, a laser is used to selectively fuse powdered material, usually plastics or metals, into solid layers. The untouched powder acts as support, allowing complex geometries to be created without the need for additional support structures.

After the printing process is complete, the 3D printed object may require additional post-processing to achieve the desired finish or functionality. This can include removing support structures, sanding or polishing the surface, and applying coatings or paints.

3D printing offers numerous advantages over traditional manufacturing methods. It allows for intricate designs with complex geometries that would be difficult or impossible to produce using traditional methods. It reduces waste, as only the necessary material is used in the printing process. It also enables rapid prototyping, allowing for quick iteration and refinement of designs.

While 3D printing has made significant advancements in recent years, there are still limitations, such as material selection, printing speed, and printing size constraints. However, ongoing research and development in the field are constantly pushing the boundaries and expanding the possibilities of 3D printing technology.

 

The Importance of Adhesion in 3D Printing

Adhesion plays a crucial role in the success of 3D printing. Without proper adhesion, the printed object may fail to adhere to the print surface, leading to warping, detachment, or misalignment during the printing process. This can result in a failed print and wasted time, material, and effort.

Adhesion refers to the ability of the printed object to firmly stick to the print surface throughout the printing process. It ensures that each new layer adheres securely to the previous layer, creating a solid and structurally sound object.

There are several factors that contribute to adhesion in 3D printing:

Print Surface: The choice of print surface material is essential. Most commonly used print surfaces include glass, BuildTak, or painter’s tape. These surfaces provide a smooth and flat base for the object to adhere to. Selecting the appropriate print surface for the type of material being used is vital for achieving good adhesion.

Leveling: Ensuring that the printer bed is properly leveled is crucial for maintaining consistent adhesion throughout the printing process. A level bed ensures that the first layer of the print is evenly deposited and adheres properly to the print surface.

Cleanliness: A clean print surface is essential for good adhesion. Dust, oils, or leftover filament remnants can hinder the object’s ability to stick to the print surface. Regularly cleaning the print surface and removing any debris or residue is essential for achieving optimal adhesion.

Temperature Settings: Different materials have specific temperature requirements for optimal adhesion. Adjusting the print bed and extruder temperatures to the recommended settings for the material being used helps improve adhesion. For example, some materials may require a heated build plate to prevent warping.

The use of a brim is a popular technique to enhance adhesion in 3D printing. A brim is a thin layer of material that extends outward from the base of the object, creating a wider area of contact with the print surface. It increases the surface area that adheres to the print surface, providing more stability and reducing the chances of the print detaching or warping.

Proper adhesion ensures that the printed object is securely anchored to the print surface, resulting in a successful print job. It promotes accuracy and precision, allowing for complex designs with overhangs or intricate details to be printed successfully.

Understanding and managing adhesion is crucial for achieving high-quality prints. Experimenting with different adhesion techniques, such as adjusting bed temperature, using adhesive sprays, or applying specialized adhesion sheets, can help optimize adhesion for specific materials and printing scenarios.

By prioritizing adhesion in 3D printing, you can significantly improve print success rates, reduce print failure, and ultimately achieve superior 3D printed objects.

 

What is a Brim

In the context of 3D printing, a brim refers to a thin layer of material that is added to the base of a 3D printed object. It extends outward from the object in a flat, sheet-like shape, creating a wider area of contact with the print surface.

The purpose of a brim is to enhance adhesion and stability during the printing process. By increasing the surface area that adheres to the print surface, a brim helps prevent the print from detaching or warping, especially for objects with a small footprint or with overhangs that might otherwise cause the print to fail.

Unlike a raft or a skirt, which are other types of adhesion structures used in 3D printing, a brim is directly connected to the object being printed. It is usually created by extruding or depositing the same material as the object itself, ensuring a seamless transition between the brim and the object.

The size and thickness of a brim can vary depending on the specific needs of the print. Typically, the width of a brim ranges from a few millimeters to several centimeters, while the thickness is usually kept relatively thin, around 0.1mm to 0.3mm. The size of the brim can be adjusted in the slicing software used for preparing the print.

A brim serves as a sacrificial layer as it is easily removed once the print is complete. It can be peeled away or trimmed off using a knife or a pair of scissors. Since the brim is connected to the object, any remnants left on the object can be easily cleaned or sanded away, leaving behind a clean and finished surface.

Adding a brim to your 3D printing process is particularly useful when working with materials prone to warping, such as ABS or nylon. These materials tend to shrink as they cool down, which can lead to detachment from the print surface. A brim provides additional adhesion and acts as a support structure for the object, preventing warping and promoting successful prints.

It’s worth noting that a brim may not be necessary for every print. Small or simple objects with a large enough base may have sufficient adhesion without the need for a brim. However, for prints with a small contact area or intricate designs, using a brim can greatly increase the chances of a successful print.
