Assembly may take several hours, so be patient.
Initial Setup and Calibration
Bed Leveling Techniques
Bed leveling is one of the most critical steps for successful 3D printing. If your bed is not level, the first layer of your print will not adhere properly, which can lead to warping or detachment of the print. There are several methods for bed leveling, including manual leveling and auto-bed leveling. With manual leveling, you adjust the height of the bed at each corner using the leveling screws until the nozzle is the correct distance from the bed. This distance can be checked with a piece of paper. Auto-bed leveling uses a sensor to measure the bed surface and adjust the Z-axis accordingly. Follow the instructions in your manual to perform either method, and repeat the process periodically.
Extruder Calibration
Extruder calibration is essential to ensure that your printer extrudes the correct amount of filament. An improperly calibrated extruder can result in under-extrusion or over-extrusion, which will affect the quality of your prints. To calibrate the extruder, you will need to measure the amount of filament the extruder is supposed to push through and then measure the actual amount. This is usually done by marking a specific length of filament and instructing the printer to extrude that length. If the actual amount extruded is different, you will need to adjust the E-steps setting in your printer’s firmware. The E-steps setting determines how many steps the extruder motor makes for each millimeter of filament extruded. It is necessary to consult online guides for detailed instructions on how to adjust this setting.
Slicing Software for Tevo Tarantula Prusa i3
Recommended Slicer Settings
Slicing software converts your 3D models into instructions (G-code) that your printer can understand. There are several excellent slicing options available, with Cura and PrusaSlicer being popular choices. Key settings to consider include: layer height (thinner layers for higher detail), print speed (adjust according to the filament), infill density (for strength), nozzle temperature (specific to the filament), bed temperature (for adhesion), and support settings (for complex geometries). Experiment with these settings to optimize your prints for quality and speed. Refer to online communities and forums for specific recommendations for your filament and printer combination.
Common Filament Types
PLA
PLA (Polylactic Acid) is a widely used filament, especially for beginners. It is easy to print with, has low warping, and is made from renewable resources. PLA requires lower printing temperatures (around 190-220°C) and does not require a heated bed, though it can be beneficial. It comes in a wide range of colors and is ideal for prototypes, decorative items, and educational projects. However, PLA is not very heat resistant and can become soft in hot environments. For example, it’s a good option for toys and display models. Storage should be in a cool, dry place, away from direct sunlight. PLA is a versatile material for general use, with good detail.
ABS
ABS (Acrylonitrile Butadiene Styrene) is a durable plastic known for its impact resistance and heat resistance. It is often used for functional parts and is commonly used in manufacturing. ABS requires a higher printing temperature (around 220-250°C) and a heated bed (around 80-110°C) to prevent warping. Printing with ABS can be more challenging than PLA due to the potential for warping and fumes, so a well-ventilated area is recommended. It is ideal for parts that need to withstand stress, heat, or physical impact, like RC car parts or phone cases. Enclosures are often recommended for ABS printing to maintain a stable temperature and reduce warping.
PETG
PETG (Polyethylene Terephthalate Glycol-modified) combines the best properties of both PLA and ABS. It’s easy to print like PLA, with minimal warping, and it has good strength and durability like ABS. PETG usually requires a printing temperature between 220-250°C, and a heated bed (around 70-80°C). PETG is a versatile material suitable for a wide range of applications, including functional parts, mechanical components, and food-safe applications. It adheres well to print beds, and produces parts with good surface finish. PETG is a good choice for beginners who want a material that is both easy to print and durable. PETG is generally considered food safe, but be sure to check the specific filament’s properties.
Troubleshooting Common Issues
Nozzle Clogging
Nozzle clogging is a common problem that can disrupt your prints. Several factors can cause a clog, including incorrect printing temperature, impurities in the filament, or simply prolonged use. Symptoms include a lack of filament extrusion or inconsistent extrusion. To address a clog, try these steps: Increase the nozzle temperature slightly to see if it melts the clog. Use a thin needle or the provided cleaning tool to push through the nozzle. Perform a ‘cold pull’ by heating the nozzle, extruding some filament, and then cooling it down to pull out any debris. In severe cases, you may need to disassemble the hot end and clean it manually. Maintaining a clean nozzle is essential for print quality.
Bed Adhesion Problems
Poor bed adhesion is another common issue, where the print does not stick to the bed surface. This leads to warping, detachment, and failed prints. Common causes include an uneven bed, incorrect bed temperature, or a dirty bed surface. To improve bed adhesion: Level your bed properly, ensuring the nozzle is the correct distance from the bed. Clean the bed surface with isopropyl alcohol to remove any oils or debris. Use adhesion aids, such as glue stick, hairspray, or painter’s tape (for PLA). Increase the bed temperature slightly. Consider using a brim or raft in your slicer settings, which provide a larger base for the print to adhere.
Print Quality Issues
Print quality issues can manifest in various ways, from layer separation to stringing and blobs. Many factors influence print quality, including temperature settings, print speed, and the quality of the filament. If you experience layer separation, try increasing the nozzle temperature. If you notice stringing or blobs, reduce the printing temperature or adjust the retraction settings in your slicer. Ensure your printer belts are properly tensioned. Slowing down your print speed can also improve quality. Fine-tuning your printer settings through trial and error is often necessary to achieve the best print quality for your specific setup.
