LeZao Tiny

Only 1KG filament needed! A textbook-sized, fully 3D printed high-speed 3D printer

🌟 Product Overview

LeZao Tiny - A fully 3D printed high-speed 3D printer designed independently by a high school student over 3 years, bringing the dream of "textbook size, fully 3D printed, high-speed printing" to reality. From the initial confusion with Voron0.1 to now having a mature product with a complete open-source solution, this is a story of perseverance and innovation.

⚠️ Important Notes

📦 Material Preparation Suggestions

• Spool holder selection: You can print one spool holder from the print profile. If using 1kg large spools, it is recommended to purchase an external spool holder or a standalone dry box to ensure print quality and material preservation.

🔧 Print Parameter Optimization

• Bottom shell limit slot: It is recommended to use tree supports for printing. The author used the "Support for PLA" setting, but you can change it to support parameters for other materials like PETG based on your actual material.

📋 Document Update Plan

• BOM List: Currently, only the print files and CAD drawings have been organized. The detailed BOM list will be completed and updated this weekend.
• Installation Tutorial: A detailed assembly tutorial is in the making and is expected to be released before National Day. Please stay tuned.

💻 Electrical Control System Description

• Current Configuration: The electrical setup uses a combination of Fly's Micro4 and Pad Mini.
• Screenless Version: The author is developing a screenless version, which is expected to be launched soon.
• Selection Recommendation: If personal use rarely involves offline situations or does not require a screen display, it is recommended to choose the upcoming screenless version for better value.

🛠️ Mechanical Parts Notes

• Linear rail E-value adaptation: The linear rail involves determining the E-value (first hole spacing). To avoid procurement issues, the author has implemented a dual adaptation design on the gantry (supporting 2 specifications).
• Y Bottom Shell Status: The adaptation of the Y bottom shell is still uncertain. It is recommended not to rush to purchase accessories yet and wait for the author to release a more detailed complete tutorial from procurement to assembly.

🔩 CNC Machined Parts

• Special Parts: 3 small parts, such as the CNC heated bed component, require STEP format files for machining.
• Cost Estimation: The machining cost is approximately between tens to 100 yuan, depending on personal operating skill and machining precision requirements.
• Beginner's Recommendation: If unfamiliar with CNC machining, it is recommended to wait for the detailed tutorial to be released before proceeding.

🤝 Future Plans

• Kit Collaboration: There is a possibility of collaborating with Mellow to launch a complete kit later. Specific collaboration details and timelines are pending and will be communicated to everyone promptly.
