About Project

When components are mounted directly to heat sources like motors, sensors, or aerospace chassis, structural integrity cannot be compromised. The DLP 3D Printed PI Cylinder Housing represents the ultimate shield for high-temperature mechanical and electronic sub-assemblies.

The primary highlight of Polyimide (PI) is its world-class thermal stability. While standard engineering plastics soften at a fraction of the temperature, our DLP-printed PI withstands continuous operating temperatures from 220掳C up to 300掳C+ without losing its shape or load-bearing capability. This heavy-lifter cylinder features robust structural mounting flanges designed to bolt securely into harsh environments. Under extreme heat and torque, regular plastics suffer from stress-relaxation, causing mounting bolts to pull through; PI remains completely rigid and immutable.

Furthermore, this housing boasts native flame retardancy (FST compliant) and supreme resistance to aggressive automotive fluids, fuels, and aerospace solvents. It serves as an indestructible shield for internal sensors, solenoids, or actuators operating in the absolute harshest conditions.

At FacFox, we have perfected the complex scaling and thermal baking profiles required to counter PI resin shrinkage, ensuring your large-walled housings fit perfectly every single time. Replace heavy metal casings and expand your design freedom today.

Solution

• Step 1: The heavy-walled housing model was configured with robust solid support anchors to withstand peel forces encountered during the liquid resin vat detachment cycle.
• Step 2: An FST-compliant (Flame, Smoke, Toxicity) thermal-grade liquid polyimide precursor was mixed and loaded into the heated printer reservoir.
• Step 3: The main thick-walled cylinder and the extended structural mounting flanges were continuously fabricated using precise ultraviolet exposure patterns.
• Step 4: The large-volume print was safely unmounted and subjected to prolonged solvent-flush washing to ensure the hollow interior channel was entirely hollowed and clear.
• Step 5: Anchor points were carefully ground down to produce uniform, smooth sealing surfaces along the mounting ears and cylinder faces.
• Step 6: A long-cycle thermal curing process exceeding 300掳C was completed in a controlled-atmosphere furnace, finalizing the rigid, chemically inert polyimide polymer structure.
