This enhances structural integrity and reduces heat absorption.

• Print speed: The speed at which the printer operates relates directly to the filament’s cooling rate. Slow printing speeds allow for better thermal bonding between layers. According to research by Wegner et al. (2019), a decrease in print speed leads to a more uniform thermal profile in the finished product, enhancing overall thermal resistance by minimizing internal stresses.

• Temperature regulation: The print temperature directly affects the viscosity of the filament. A higher temperature can lead to improved flow but may also degrade the material. A study by Berretta and Zinn (2020) noted that maintaining consistent temperature control during printing can help maximize the filament’s heat resistance. For instance, if the filament cools too quickly, it can create internal defects, thereby reducing thermal performance.

• Cooling settings: The use of cooling fans during the printing process also plays a crucial role. Proper cooling can help solidify the printed layers more effectively. Research indicated that inadequate cooling can lead to poor layer bonding and decreased thermal resistance (Simpson et al., 2021).

• Material choice: The thermal properties of the filament itself are essential. Materials like nylon or polycarbonate have inherently higher thermal resistance compared to PLA. As noted in a review by Kita et al. (2020), the choice of filament material must align with the desired thermal resistance required for the application.

Each printing setting interacts with the filament’s properties, thereby impacting the thermal resistance of the final print. Adapting these settings according to material specifications can optimize performance for various applications.
