The most relevant group to review this topic would be the Advanced Desktop Fabrication and Fluid Dynamics Collective. This group values innovative manufacturing processes using accessible tools but remains highly critical of efficiency, scalability, and material science choices.
Here is the abstract and summary, framed according to their skeptical, efficiency-focused perspective.
Abstract
This submission details an iterative engineering solution for the fabrication of custom liquid cooling distribution plates ("Distro Plates") without relying on traditional Computer Numerical Control (CNC) machining. The core problem—layer-based leakage in 3D-printed fluid channels—is effectively rejected by repositioning the 3D-printed part or laser-cut acrylic not as a fluid channel itself, but as a mold for a single, comprehensive platinum silicone gasket. Multiple iterations refine the process, moving from large 3D-printed forms to a more efficient, all-acrylic, laser-cut molding assembly. Critical findings include successful high-pressure sealing (demonstrated up to 50 PSI), process scaling challenges necessitating an injection method, and a key material incompatibility between thermoplastic polyurethane (TPU) and platinum silicone curing agents. The final design provides a functional, high-resolution alternative to traditional CNC manufacturing, though its scalability for large volumes and efficiency relative to industrial processes remain questionable.
I Fixed The Biggest Problem with 3D Printed Water Cooling (Review)
1:13 Rejecting the Premise: The central innovation is recognizing that fused filament fabrication (FFF) prints are unsuitable for fluid retention under pressure (2:11). The solution bypasses this limitation entirely by using the print only as a constrained form for a custom-molded silicone gasket (2:18), which then handles the sealing. Pragmatic.
2:55 Pressure Validation: The design targets high confidence by successfully handling 50 PSI, significantly exceeding typical cooling loop pressures (5 PSI). The initial reliance on a 3D-printed barb fitting failed immediately (3:10), necessitating an immediate switch to a more robust threaded connection (3:19).
5:17 Efficiency Iteration (Molding): The process improved by using the final acrylic sheets as part of the mold assembly, reducing unnecessary 3D print volume and improving visualization of the silicone propagation (5:33).
8:53 Material Science Failure: Using TPU (a flexible filament) for the mold shims inhibited the curing of the platinum silicone, resulting in a large, messy volume of uncured goo (10:29). This is a known incompatibility issue (sulfur compounds); switching back to standard PLA resolved the chemical problem (10:41), requiring manual flashing cleanup instead.
10:56 Process Scaling Solution: Gravity filling proved inadequate for larger forms (10:00), leading to incomplete filling and air bubbles. The adoption of syringe injection (10:56) successfully mitigated bubble ingress and ensured complete mold filling, which is essential for consistent results.
11:33 Mechanical Retention: Small holes added to the acrylic channel allow silicone to cure through, mechanically locking the finished gasket to the structure (11:42). A necessary functional improvement for assembly ease.
14:48 Scalability Bottleneck: The final full-scale prototype pour failed to fully traverse the main reservoir channel from a single injection point before curing, requiring manual injection from the opposite side ("cheating") to complete the fill (14:57). This highlights a clear constraint on the current process scaling for large, complex channels.
16:59 Conclusion: The resulting distribution plate assembly is demonstrably leak-free after one week of continuous operation (17:08). While the iterative development process is clever, the final manufacturing steps are highly labor-intensive (silicone mixing, degassing, injection, manual trimming, tapping, assembly), confirming this method is best suited for complex, low-volume custom work rather than efficient production.
