Building and Calibrating Your Own DIY 3D Printed 3D Printer: A Comprehensive Guide

3D printing has revolutionized rapid prototyping and DIY projects, with 3D printed 3D printers becoming increasingly popular among enthusiasts. A DIY 3D printed 3D printer not only allows you to customize your build but also provides a hands-on learning experience. In this article, we will delve into the working principle of a DIY 3D printed 3D printer and provide a detailed guide on calibrating the NEWAY 3D printed printer.

Benefits of a DIY 3D Printed 3D Printer

Customizability

One of the most significant advantages of a DIY 3D printed 3D printer is the ability to customize every aspect of the build. You can choose components that suit your specific needs, such as a larger print bed or a more powerful extruder. This flexibility ensures that your printer is tailored to your requirements, making it more versatile and efficient.

Cost-effectiveness

Building your own 3D printed 3D printer can be substantially cheaper than purchasing a pre-assembled model. You can source individual components or kits that offer better value for money. This approach allows you to invest in quality parts that provide long-term durability and performance, making the overall cost more economical.

Hands-on Experience

Assembling a DIY 3D printer from scratch is an educational experience that enhances your understanding of 3D printing technology. It teaches you how each component functions and how the printer operates as a whole. This knowledge is invaluable for troubleshooting and optimizing your printing process.

Components of a 3D Printed 3D Printer

3D Printed Extruder

The extruder is a crucial component of any 3D printer. It melts plastic filament and deposits it layer by layer to create the final object. In a 3D printed 3D printer, the extruder is custom designed to work with different types of filament. Components such as the hotend, cooling fan, and drive gear are often 3D printed to specification, ensuring precise control over filament flow.

Print Bed

The print bed is the surface where the layers of the printed object are deposited. For a DIY 3D printed 3D printer, the print bed can be made of various materials such as glass or metal. It's essential to ensure the print bed is level and able to hold the printed object securely. Adding features like a magnetic bed allows for easy removal of printed objects.

Mechanisms

Mechanisms in a 3D printer include the axes (X, Y, and Z) that move the extruder and the print bed. These are typically actuated by stepper motors, which provide precise control over the movement of the print head. The frame structure supports the moving parts and ensures stability during the printing process.

Electronics

The control board and motherboard are the brain of the 3D printer. They manage the movement of the extruder and print bed, temperature control, and other critical functions. Customizing these components allows you to optimize performance and achieve better print quality.

Step-by-Step Guide to Calibrating the NEWAY 3D Printed Printer

Calibrating your 3D printer is essential to ensure optimal print quality. Here's a detailed guide to calibrating the NEWAY 3D printed printer:

Preparing the Printer

Before calibration, ensure all components are correctly assembled. This includes mounting the extruder, attaching the print bed, and connecting the control board. Check the wiring and ensure all connections are secure.

Initial Setup

1. Connect the Printer: Connect the control board to your computer via USB. Install the necessary drivers and software (such as Repetier Host or Cura).
2. Power On the Printer: Turn on the power supply and wait for the printer to initialize.
3. Check Firmware: Ensure the firmware is up-to-date. This can be done through the slicing software or directly through the control board.

Calibrating the Print Bed

1. Level the Print Bed: Use a digital caliper or a leveling tool to ensure the print bed is level. Adjust the screws to make sure the bed is perfectly flat.
2. Apply Adhesive: Apply a layer of adhesive (such as PLA filament) to ensure the printed object sticks to the bed. For the NEWAY printer, the recommended adhesive is a fine layer of BuildTak.
3. Heat the Bed: Preheat the print bed to the appropriate temperature (usually around 60C for PLA) to ensure the object adheres correctly.

Adjusting the Extruder

1. Extruder Mounting: Ensure the extruder is properly mounted to the frame. Adjust the screws to tighten the extruder and ensure it's securely attached.
2. Extruder Alignment: Check the alignment of the extruder to the print bed. Use a piece of paper to test the distance between the nozzle and the bed. The paper should fit snugly but not too tightly.
3. Temperatures: Adjust the extruder temperature settings to ensure it melts the filament correctly. The recommended temperature for PLA is around 200C.

Fine-Tuning Print Quality

1. Layer Height: Experiment with different layer heights to determine the best setting for your prints. For most applications, a layer height between 0.1mm and 0.2mm provides a good balance between print quality and speed.
2. Infill Percentage: Determine the appropriate infill percentage for your prints. A higher infill percentage increases print strength but extends printing time.
3. Retraction Settings: Fine-tune retraction settings to prevent oozing and stringing. A retraction distance of around 1.5mm and speed of 50mm/s typically work well for PLA prints.

Best Practices for Assembling and Maintaining Your DIY 3D Printed 3D Printer

Proper maintenance ensures your 3D printer runs smoothly and produces high-quality prints. Here are some best practices:

Storage Tips

• Dry Environment: Store your printer in a dry environment to prevent corrosion of metal components.
• Covering: Cover the printer when not in use to protect it from dust and debris.
• Temperature Control: Keep the printer in a stable temperature range. Extreme temperature fluctuations can affect print quality and hardware longevity.

Cleaning Procedures

• Routine Cleaning: Regularly clean the print bed and extruder to remove residual filament and debris. Use isopropyl alcohol or a degreaser to clean the print bed.
• Extruder Nozzle: Clean the extruder nozzle with a thorough cleaning tool or by printing a cleaning cube.

Common Issues and Solutions

• Extruder Clogging: Preheat the extruder and use a cleaning filament to unclog the nozzle. Regular cleaning during printing can prevent clogging.
• Layer Separation: Ensure the print bed is level and the adhesive is applied correctly. Adjust print settings like layer height and infill to improve adhesion.
• Overheating: Monitor the temperature of the printer components. Use cooling fans to dissipate heat and prevent overheating.

Recommended Maintenance Schedule

• Monthly:
• Check the print bed level and adhesive condition.
• Inspect all connections and tighten any loose screws.
• Quarterly:
• Clean the extruder and nozzle.
• Check for wear and tear on belts and bearings.
