Summary:
A cost-effective DIY upgrade for diode laser engravers. This air assist nozzle directs compressed air into the cutting path to reduce charring, increase cutting depth, and protect the laser lens. Designed specifically for 33mm x 33mm square laser modules.
Description:
## 💡 Project Overview This printable nozzle is designed to significantly improve the cutting quality of your diode laser. By creating a focused air stream, it clears smoke and debris instantly, ensuring the laser energy hits the material directly without obstruction.
## 📏 Compatibility & Dimensions
- Fits: Square diode laser modules with a body size of 33mm x 33mm.
- Total Nozzle Dimensions: ~42.5mm (L) x 33mm (W) x 38mm (H).
- ⚠️ Important: Please measure your laser module and check for clearance around your machine (gantry/frame) before printing to ensure it fits.
## ✨ Key Benefits
- Cleaner Cuts: Blasts away smoke and soot, resulting in lighter, cleaner edges on wood and acrylic.
- Lens Protection: Prevents smoke and residue from rising up and sticking to the optical lens, extending the life of your laser.
- Deeper Penetration: Clears the optical path, allowing the laser to cut deeper and faster per pass.
- Safety: Helps suppress minor flare-ups during cutting.
## ⚙️ Print Settings (Crucial)
- Material: PETG, ABS, or ASA is highly recommended.
- Note: Avoid standard PLA as the heat radiating from the laser head or the workpiece can cause it to soften and deform.
- Infill: 100% (Solid) or at least 4 walls.
- Reason: High density is needed to prevent air leakage through the walls and ensure structural integrity.
- Supports: Yes (Likely required for the internal air channel or overhangs, depending on orientation).
- Layer Height: 0.2mm or finer for smoother threading/fitting.
## 🛠️ Hardware Needed
- Air Pump: An aquarium pump or specialized laser air compressor.
- Tubing: Flexible silicone or PU tubing (Check the model port size, typically fits 4mm/6mm tubing).
- Mounting: Designed for a friction fit or to utilize existing mounting points on the 33mm module.
