Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →The CCTREE PLA 3D Printing Filament 1.75mm – Transparent Green is a versatile, beginner-friendly filament for FDM 3D printers. PLA (Polylactic Acid) is the most popular 3D printing material for good reason: it prints easily at low temperatures, doesn't require a heated bed or enclosure, and produces clean, detailed parts with minimal warping.
This spool delivers a vibrant Transparent Green finish with tight diameter tolerance for reliable feeding. Whether you're printing cosplay props, desk organizers, prototypes, or educational models, PLA is the ideal starting point.
| Property | PLA | ABS |
|---|---|---|
| Ease of printing | Very easy — great for beginners | Needs heated bed + enclosure |
| Heat resistance | ~60 °C glass transition | ~105 °C glass transition |
| Strength | Rigid but brittle | Tougher, more impact-resistant |
| Surface finish | Smooth, glossy | Matte; acetone-smoothable |
| Odor | Minimal (slightly sweet) | Mild fumes — needs ventilation |
| Biodegradable | Yes (industrial compost) | No |
Figurines, toys, cosplay armor, phone stands, vases, plant pots, educational models, architectural mockups, desk accessories, cookie cutters (with food-safe coating), and rapid prototypes.
Works with virtually any FDM printer — Creality Ender, Creality CR series, Prusa, Anycubic, and more. A standard 0.4 mm brass nozzle is all you need.
