Different types of 3D printers

There are several types of 3D printers available on the market, each with its own strengths and limitations. The most common types include:

1. Fused Deposition Modeling (FDM): FDM printers use a heated nozzle to melt and extrude a thermoplastic filament, which is then deposited layer by layer to create the object. This is the most widely used type of 3D printer and is known for its affordability and ease of use.

2. Stereolithography (SLA): SLA printers use a laser to selectively cure a liquid resin, creating solid layers that build up to form the object. SLA printers are capable of producing highly detailed and intricate prints, making them popular in industries such as jewelry and dentistry.

3. Selective Laser Sintering (SLS): SLS printers use a laser to selectively fuse powdered materials, such as nylon or metal, to create the object. SLS printers are known for their ability to produce strong and durable prints, and are commonly used in industrial applications.

4. Digital Light Processing (DLP): DLP printers work similarly to SLA printers, but instead of using a laser, they use a digital light projector to cure the resin. DLP printers offer high print speed and resolution, making them suitable for applications that require fine details.

Choosing the right type of 3D printer depends on factors such as budget, intended use, and desired print quality. It is important to consider these factors before making a purchase to ensure that the chosen printer meets your specific requirements.

Tip #1: Change print orientation

Increases strength of the print

One of the key factors influencing the strength of a 3D print is its orientation during the printing process. The orientation refers to how the object is positioned on the build plate of the 3D printer. By changing the print orientation, it is possible to significantly increase the strength of the print.

When a model is printed vertically, the layer lines become the weakest points of the print. This is because the layers are stacked vertically, making them susceptible to breaking along the layer lines. However, by simply changing the orientation to horizontal, the strength of the print can be greatly enhanced.

Printing an object horizontally reduces the reliance on the layer lines for strength. Instead, the walls of the object become the primary source of strength. This can be seen in the example mentioned earlier, where the vertically printed model easily broke along the layer lines, while the horizontally printed model remained intact.

In addition to increasing strength, changing the print orientation can also have a positive impact on print quality. By considering the orientation of the object on the build plate, it is possible to minimize the need for support structures, which can leave marks on the print surface. This results in a cleaner and more aesthetically pleasing print.

It is important to note that having a good understanding of print orientation comes with experience. The more prints you create, the better you will become at determining the optimal orientation for each object. By considering factors such as support requirements and material usage, you can achieve stronger and higher quality prints.

Tip #2: Add fillets

Strengthen weak points in the print

Another tip for improving the strength of your 3D prints is to add fillets to weak points in the design. A fillet is a curved surface that is created at the intersection of two surfaces, such as the connection between a gear and a shaft. By adding fillets, the stress concentration at these weak points can be reduced, making the print less prone to failure.

Weak points in a 3D print often occur at sharp corners or edges, where stress tends to accumulate. Without proper reinforcement, these areas are more susceptible to cracking or breaking. However, by incorporating fillets, the stress is distributed more evenly, resulting in a stronger and more durable print.

To add fillets, you can use 3D modeling software, such as Fusion 360 or any other software that offers filleting capabilities. Simply select the edges or corners that need to be filleted and specify the desired radius or size of the fillet. It is important to strike a balance between adding sufficient strength and maintaining the desired aesthetics of the print.

The size of the fillet depends on various factors, including the material being used, the size of the object, and the level of stress it will be subjected to. It is recommended to experiment with different fillet sizes to determine the optimal configuration for your specific needs.

By addressing weak points through the addition of fillets, you can greatly enhance the overall strength and longevity of your 3D prints. This technique is particularly useful for functional prints or objects that will be subjected to external forces or stress.

Tip #3: Add screws or insert objects

Make print stronger

In addition to changing the print orientation and adding fillets, another effective way to improve the strength of your 3D prints is to incorporate screws or insert objects into the design. This technique is especially useful for reinforcing connections or creating secure joints between different parts of a print.

When printing objects that require assembly, such as mechanical components or prototypes, relying solely on the interlocking features of the print may not provide sufficient strength. By adding screws or inserting objects, you can ensure a more secure and robust connection.

To implement this technique, you will need to design your print with appropriate holes or channels to accommodate the screws or objects. These holes should be sized to fit the chosen hardware or inserts precisely, ensuring a snug and secure fit.

By screwing together multiple printed parts, the overall strength of the assembly can be greatly enhanced. This is especially effective when dealing with components that will experience significant forces or stress during use. The threaded connection provided by screws ensures a more reliable and long-lasting joint.

Alternatively, inserting objects such as metal rods or dowels into the print can also reinforce the structure and add stability. This technique is commonly used in applications such as furniture or structural components, where additional strength is required.

When incorporating screws or inserts into a 3D print, it is important to consider factors such as the size and type of hardware, the material being printed, and the intended use of the object. Proper alignment and precision are crucial for achieving optimal results.

By utilizing screws or insert objects, you can significantly increase the strength and durability of your 3D prints, making them suitable for a wide range of applications and demanding environments.

Tip #4: Adjust print sequence setting

Print objects one by one

The print sequence setting is a powerful tool that can greatly improve the quality and efficiency of your 3D prints. By adjusting this setting, you can instruct the 3D printer to print objects one by one, rather than all at once. This can help mitigate certain print issues and improve overall print success.

When multiple objects are printed simultaneously, it can lead to problems such as stringing and interference between objects. Stringing occurs when excess filament is left behind during travel moves, resulting in unsightly strands connecting different parts of the print. Interference occurs when objects collide or overlap during the print, causing misalignment or failed prints.

By enabling the print sequence setting, the 3D printer will print each object individually, minimizing the risk of stringing and interference. This means that one object will be completed before moving on to the next, ensuring cleaner and more accurate prints.

However, it is important to exercise caution when using the print sequence setting, as it may introduce new challenges. For example, if objects are placed too close together or if the printer’s build plate has limited space, there may not be enough room for the nozzle to move between objects without colliding. This could result in failed prints or damage to the printer.

To make the print sequence setting work effectively, consider the size and positioning of your objects on the build plate. Leave appropriate spacing between objects to allow for proper nozzle movement and avoid collision. It may be necessary to remove certain objects or adjust the print sequence for complex prints with intricate designs.

By taking advantage of the print sequence setting, you can improve print quality, reduce stringing issues, and minimize interference between objects. However, careful planning and consideration of print layout are essential for achieving optimal results.

Tip #5: Consider tolerance for threads

Use Fusion 360 extension for designing perfect 3D printed threads

When designing objects with threaded connections, it is crucial to consider tolerance to ensure proper fit and functionality. Without appropriate tolerance, threads may be too loose or too tight, resulting in weak or non-functional connections. To overcome this challenge, Fusion 360 offers an extension specifically designed for creating perfect 3D printed threads.

The Fusion 360 Thread command provides advanced options for designing threads that are suitable for 3D printing. This extension allows users to specify parameters such as thread pitch, major and minor diameters, and length. By inputting the desired values and selecting the appropriate thread profile, Fusion 360 automatically generates a 3D model with accurate and functional threads.

The benefit of using the Fusion 360 Thread command is that it takes into account the material shrinkage and expansion that occurs during the 3D printing process. This ensures that the printed threads fit precisely with their corresponding counterparts, creating strong and reliable connections.

To use this extension effectively, it is important to have a solid understanding of thread specifications and the requirements of your particular application. Consider factors such as load-bearing capacity, desired torque, and the material properties of your print when selecting thread parameters.

By using Fusion 360’s thread extension, you can eliminate the guesswork and trial-and-error often associated with creating 3D printed threads. This results in more accurate and functional prints, saving both time and material.

In conclusion, by considering tolerance for threads and utilizing the Fusion 360 extension, you can achieve perfectly fitting and robust threaded connections in your 3D prints.

Creating a 3D model is just the first step towards producing a successful print. To ensure optimal print quality and performance, it is important to optimize your models specifically for 3D printing. This involves considering factors such as print orientation, support structures, and material usage.

As mentioned earlier, changing the print orientation can greatly impact the strength and aesthetics of the print. By carefully positioning your model on the build plate, you can reduce the need for support structures and minimize the occurrence of visible layer lines. This can result in cleaner and more visually appealing prints.

Support structures are often necessary when printing overhanging or complex geometries. However, they can leave marks or blemishes on the surface of the print, which may require additional post-processing. By designing your model with self-supporting features or utilizing software tools to generate custom support structures, you can achieve cleaner prints with minimal post-processing.

Another important consideration is material usage. Different materials have varying properties and requirements for successful printing. Factors such as print temperature, cooling time, and layer height must be optimized to ensure proper adhesion and fusion between layers. Consulting material-specific guidelines and performing calibration prints can help fine-tune these settings for optimal results.

By optimizing your models for 3D printing, you can achieve prints that not only look great but also function as intended. Taking the time to refine your designs and consider the unique requirements of 3D printing will yield higher-quality prints and reduce the likelihood of failed or subpar results.
