In this segment of the video, upgrades and modifications for the Creality CR30 3D printer are discussed. The focus is on reducing the printer’s noise levels. The main sources of noise are identified as the motherboard fan and the power supply fan. By adding standoffs to create a gap under the fan and adjusting the voltage to reduce its speed, considerable reduction in noise levels is achieved without impacting thermal performance significantly. Thermal testing results are monitored, demonstrating the impact of the modifications on temperature levels in the printer components.

In this part of the video, the content creator tests a fan cover for the power supply to reduce noise, but finds it hampers airflow and increases internal air temperature to 35 degrees Celsius. They then upgrade to the Meanwhile UHP350 power supply for noise reduction, improved efficiency, and encapsulated components for protection. The new power supply is 6% more efficient, saving about 5% power consumption. The creator reuses most AC and DC wiring, adds an extra ground wire, and mounts the power supply using the original holes and aluminum brackets due to unavailability of a drill for new holes.

In this segment of the video, the speaker powers up the unit and verifies everything is working. They conduct sound testing and find low decibel levels and good temperatures. The speaker then adds new printer feet made of flexible filament, organizes spare parts and tools, and creates a tool holder for the printer. They also design an origami box for spare parts, demonstrating how to embed magnets and attach the box securely. The segment concludes with the speaker upgrading the PTFE tube with Capricorn tube by replacing the section inside the heat sink.
00:09:00
In this part of the video, the key actions are focused on upgrading the 3D printer. The Capricorn tube is preferred over PTFE for its higher melting point. It emphasizes getting a square cut on the tube and removing debris from the hot end. Special beveled washers are used for assembly, ensuring proper alignment. A grounding terminal is mentioned. An acrylic sheet is added to prevent cats from accessing the printing bed. The upgrades are tested with a longer print job for quality inspection.
00:12:00
In this part of the video, the speaker mentions that after upgrades, the printing quality has improved, with a six-hour print showing smooth and consistent results, aside from some dirt on the bottom. They are happy with the outcome and plan to move the printer to its permanent location. The video concludes with the anticipation of smoother printing and an invitation to join them for future content at Desktop Inventions.
