Step 1: Preparing the TPU Filament

TPU (Thermoplastic Polyurethane) is a flexible and elastic material commonly used in 3D printing. To make the TPU infill squishy and pliable, it’s essential to prepare the filament before printing. Here are the steps to prepare the TPU filament:

  1. Inspect the filament: Before using the TPU filament, visually inspect it for any signs of damage or contamination. Check for knots, kinks, or excessive dust that may affect the printing process.
  2. Store the filament properly: TPU is susceptible to moisture absorption, so it’s crucial to store the filament in an airtight container with a desiccant pack. This will help maintain its flexibility and prevent printing issues.
  3. Preheat the printer bed: TPU is best printed onto a heated bed. Preheat the printer bed to the recommended temperature according to the manufacturer’s guidelines.
  4. Load the TPU filament: Insert the TPU filament into the printer’s filament path or extruder. Make sure it is properly seated and secured to ensure a smooth extrusion process.
  5. Purge the extruder: To ensure that any previous material is cleared from the extruder, extrude a small amount of filament before starting the actual printing process. This will help avoid any possible contamination or clogging.
  6. Perform a test print: Before printing the TPU infill, it’s a good practice to perform a test print. This will help you verify the extrusion settings, bed adhesion, and overall print quality.

By following these steps, you can effectively prepare the TPU filament for printing the squishy infill. Remember to refer to your 3D printer’s user manual and adjust the settings accordingly to ensure the best results with TPU filament.

Step 2: Adjusting the Extrusion Temperature

TPU filament requires specific extrusion temperature settings to ensure optimal printing results. Unlike rigid materials, TPU is more sensitive to temperature fluctuations, so it’s crucial to adjust the extruder temperature appropriately. Follow these steps to adjust the extrusion temperature for printing the TPU infill:

  1. Refer to the manufacturer’s guidelines: Consult the manufacturer’s recommendations for the ideal extrusion temperature range for the specific TPU filament you are using. Different TPU brands may have slightly different temperature requirements.
  2. Start with a lower temperature: Begin by setting the extrusion temperature towards the low end of the recommended range. This helps prevent excessive heat that can lead to stringing or oozing during the printing process.
  3. Conduct temperature tests: Print a small test object using the lower temperature and examine the results. Look for any issues like under-extrusion, poor layer adhesion, or excessive warping. If these issues are present, gradually increase the temperature and repeat the test until the desired print quality is achieved.
  4. Avoid excessive heat: While it’s essential to reach the optimal extrusion temperature, be cautious not to go too high. Excessive heat can cause the TPU filament to degrade or become too fluid, resulting in poor print quality or even clogs in the extruder.
  5. Take note of the successful temperature: Once you find the ideal extrusion temperature that produces high-quality prints with the TPU infill, make a note of it for future reference. This will help streamline your printing process and ensure consistent results.

Adjusting the extrusion temperature is crucial for achieving successful prints with TPU infill. It may require some trial and error to find the ideal temperature for your specific printer and TPU filament. Remember to document your findings and make any necessary adjustments to optimize the temperature settings for future prints.

Step 3: Setting the Infill Density

The infill density determines the amount of material that will fill the interior of your 3D printed object. When it comes to creating a squishy TPU infill, adjusting the infill density is crucial. Follow these steps to set the appropriate infill density for your TPU prints:

  1. Consider the desired squishiness: Before adjusting the infill density, consider how squishy you want your printed object to be. A higher infill density will result in a more rigid structure, while a lower density will create a softer and more flexible outcome.
  2. Balance between strength and squishiness: It’s important to strike a balance between strength and squishiness. Lower infill densities are ideal for objects that require flexibility, such as phone cases or stress balls, while higher densities are suitable for more structural parts like brackets or prototypes.
  3. Experiment with different densities: Start by testing different infill densities to determine the optimal squishiness for your specific object. Print a small test piece with varying infill percentages, such as 10%, 20%, 30%, and so on, to evaluate the level of flexibility achieved at each density.
  4. Consider the structural integrity: While aiming for a squishy infill, it’s important to consider the overall structural integrity of your printed object. Ensure that the chosen infill density provides enough support for the external layers and any functional requirements of the object.
  5. Adjust based on the object’s purpose: The infill density can also be adjusted based on the purpose of the printed object. For example, if you are printing a cushion or a shoe insole, a lower density would be more comfortable, while a higher density may be preferred for a toy or tool handle that requires a sturdier construction.

By experimenting with different infill densities and considering the intended purpose of your printed object, you can achieve the desired level of squishiness with the TPU infill. Remember to take into account the balance between flexibility and structural integrity to ensure optimal print results.

To make TPU infill squishy, decrease the infill density in your 3D printing settings. A lower infill percentage will result in a softer and more flexible final product.

Step 4: Customizing the Infill Pattern

Customizing the infill pattern allows you to add a personal touch to your 3D printed object. When it comes to creating a squishy TPU infill, choosing the right infill pattern can enhance its flexibility and compressibility. Follow these steps to customize the infill pattern for your TPU prints:

  1. Explore different infill patterns: Most 3D printing software offers various infill patterns, such as honeycomb, grid, triangles, or gyroids. Each pattern has its own unique characteristics, which can affect the squishiness and strength of the printed object.
  2. Consider the desired flexibility: The choice of infill pattern can significantly impact the flexibility of the printed object. Patterns with larger voids or more open spaces, like honeycomb or gyroids, tend to provide greater flexibility and squishiness. On the other hand, patterns with denser structures, like grids or triangles, can result in a more rigid infill.
  3. Experiment with different patterns: Print small test pieces with different infill patterns to evaluate their impact on the squishiness of the TPU infill. Adjust the infill percentage along with the pattern to fine-tune the level of compressibility and flexibility.
  4. Consider the print time and material usage: Keep in mind that complex infill patterns may increase the print time and require more material compared to simpler structures. Consider the trade-off between the desired squishiness and the time and material constraints of your project.
  5. Combine different patterns: You can also experiment with combining different infill patterns in a single print to create unique and customized effects. This can add visual interest to your printed objects while maintaining the desired level of squishiness.

By exploring different infill patterns and understanding their impact on flexibility and compression, you can tailor the infill pattern to achieve the desired level of squishiness for your TPU prints. Experimentation and testing with different patterns and percentages will help you find the perfect combination for your specific project.

Step 5: Printing the TPU Infill

Now that you have prepared the TPU filament, adjusted the extrusion temperature, and customized the infill settings, it’s time to start printing the TPU infill. Follow these steps to ensure a successful print with the desired squishy infill:

  1. Prepare the printer: Make sure your 3D printer is properly calibrated and leveled. Ensure that the printer bed is clean and free from any debris or residue that may affect adhesion.
  2. Select the appropriate print settings: Set the desired layer height, print speed, and wall thickness according to your specific project requirements. Refer to the manufacturer’s recommendations for optimal settings when printing with TPU filament.
