Here are some guidelines to help you make an informed decision, considering factors like strength, flexibility, color, etc:

1. Strength: Consider the strength and durability requirements of the final printed object. If you need a strong and durable part, materials like ABS, PETG, or Nylon may be more suitable than PLA. For decorative or prototyping purposes, PLA might be sufficient.

2. Heat resistance: For projects that require higher heat resistance, ABS or PETG is a better option than PLA. Resins formulated for high-temperature resistance can also be considered if you are using an SLA or DLP printer.

3. Chemical resistance: If your object needs to withstand exposure to chemicals or moisture, PETG, ABS, or Nylon might be more suitable due to their better chemical resistance properties compared to PLA.

4. Color and finish: Consider the color and finish you desire for your project. PLA is available in a wide range of colors and finishes, including matte, glossy, metallic, and even color-changing options. ABS and PETG also come in various colors, though the selection may be less extensive.

5. Ease of printing: For beginners or those looking for an easy-to-print material, PLA is often the best choice due to its low melting temperature and minimal warping. ABS and PETG may require more fine-tuning of print settings and proper bed adhesion techniques.

6. Cost: The cost of consumables can vary depending on the material type and quality. PLA is generally the most affordable, followed by ABS and PETG. Specialty materials like TPU, TPE, or Nylon may be more expensive. Consider the cost of the material in relation to your budget and the requirements of your project.

7. Printer compatibility: Ensure that the material you choose is compatible with your 3D printer. Some printers may have specific temperature, speed, or extruder requirements that may limit the range of materials that can be used.

Here are some tips on how to store and handle printing materials correctly:

1. Store in a cool, dry place: Keep your printing materials in a cool and dry environment, away from direct sunlight, heat sources, or high humidity. High temperatures can cause filament to soften or degrade, while excessive humidity can lead to moisture absorption, which can affect print quality.

2. Use airtight containers: To prevent moisture absorption, store your filaments in airtight containers or resealable plastic bags. Adding desiccant packs, such as silica gel, to the container can help maintain low humidity levels and absorb any residual moisture.

3. Keep materials on spools: Store filament materials on their original spools or use a spool holder to keep the filament organized and prevent tangling. Ensure the filament end is secured to prevent unraveling.

4. Label materials: Clearly label your materials with the type of filament, color, and any specific printing settings or temperature requirements. This will help you quickly identify the correct material for your project and prevent confusion or mistakes when loading the filament.

5. Keep materials clean: Make sure your hands are clean when handling filaments to avoid transferring oils, dirt, or other contaminants that may affect print quality. Similarly, ensure that the printer's extruder and print bed are clean before starting a print.

6. Inspect materials before use: Check the filament for any signs of damage, such as cracks, kinks, or inconsistencies in diameter, which may affect print quality. If you notice any issues, it may be necessary to discard the affected portion of the filament or replace it entirely.

7. Monitor shelf life: Some materials, particularly specialty or experimental filaments, may have a limited shelf life. Be aware of any expiration dates or recommended storage durations for your materials and use them accordingly.

1. Temperature:
  - Nozzle temperature: Each filament type has a specific temperature range for optimal printing. Consult the manufacturer's recommendations and start with the suggested temperature. Adjust the temperature in small increments (usually 5°C) if you encounter issues like poor layer adhesion or stringing.
  - Bed temperature: Some materials, such as ABS and PETG, require a heated bed to ensure proper adhesion and prevent warping. Refer to the manufacturer's guidelines for the recommended bed temperature, and adjust as needed to achieve optimal adhesion.

2. Printing speed:
  - Different materials may require different printing speeds to achieve the best results. In general, slower speeds (30-50 mm/s) are recommended for materials like ABS or flexible filaments, while PLA and PETG can typically be printed at higher speeds (50-80 mm/s).
  - Slowing down the printing speed for the first few layers can help improve bed adhesion and reduce the risk of warping.
  - Adjust the speed in increments of 5-10 mm/s to find the optimal setting for your material, balancing print quality and printing time.

3. Layer height:
  - The layer height determines the resolution and print time of your project. Smaller layer heights (e.g., 0.1 mm) result in higher resolution prints but take longer to complete, while larger layer heights (e.g., 0.3 mm) print faster but may have a rougher surface finish.
  - Choose a layer height based on your project's requirements and the capabilities of your 3D printer. In general, a layer height between 0.1 and 0.3 mm is suitable for most materials and applications.

4. Additional settings:
  - Retraction: Adjusting retraction settings can help reduce stringing or oozing when using materials like PETG or flexible filaments. Experiment with retraction distance and speed to minimize these issues.
  - Cooling: PLA usually benefits from active cooling using a part cooling fan, which helps solidify the material quickly and improves print quality. ABS and other high-temperature materials may require less cooling or even no cooling at all to prevent warping and ensure proper layer adhesion.
  - Infill and shell settings: For stronger prints, increase the infill percentage and the number of shells (perimeter layers). This will result in denser and sturdier parts, particularly when using materials like ABS or Nylon.
