The project started as a 1 meter Cartesian Cube. But for easy transportation around the house, I had to reduce the printer width to 83 cm from 1 meter. Printer details can be found below ; Max tested printing speed : 150mm/s Best results as of now : 75mm/s with 550 acceleration & 0.04 junction Deviation Printer dimensions : Length : 120 cm Width : 83 cm Height : 83 cm Current Print Dimension : 60 × 60 × 50 cm Print Dimension upgradable : 120*83*83 cm Endstops set to : 48x * 38y * 28z cm Firmware : Marlin 2.0.6.1 upgraded to 2.0.8.2 with SKR2 Steps per unit A4988 (100, 100, 2600, 95) DRV8825 (200, 200, 5200, 190) Iinear Advancement K = 0.22 Baud 250000 # printing Material (All metal) [PLA, ABS, Nylon, ASA, TPU etc] # 1.75mm filament # 100k ntc b 3950 Thermistor # 12v 40w heating cartridge # E3D V6 All Metal J-Head Hotend Extruder PID Tuning 195°c Kp : 41.88 Ki : 7.41 Kd : 59.18 185°c Kp : 42.65 Ki : 7.23 Kd : 62.90 # Fat Nema extreme Extrusio...
The idea was sparked as i was walking to the town, where i notice thrown away LED Bulbs polluting the grasslands.
Later that day, Mels3D modified V020A2 Table lamp and made it into a prototype Bulb. The casing, Body is 3D printed with eco-friendle biodegradable PLA.
RECYCLABILITY
The major disadvantage of the LED lights available in the market is that once it fails, its impossible to repair. Companies seal the body with strong adhesives and mount the PCB in a way that it cant be taken out without ripping off the wires. Hence the customers are forced to buy new. From a eco-friendly prespective, over time it creates a lot of E-Waste.
An average household has about 10 LED, in which personally we had to replace or buy new 3 of them in the last 6 months. Over time the brightness of LED reduces, only if there was a way to replace those LEDs.
The Bulbs we made consists of LED modules which can be replaced easily, solving the major problems mentioned above.
LIGHT COMPARISON
The color of the 3D print determines the color of the Light emitted. As it was a prototype, The yellow PLA used shows average readability showing promising signs for testing it with White and transparent PLA Filaments.
TYPICAL LED VS MELS3D LED-BULBS
Even if the 3D printed LED BULBS wouldn't cut it for a home lighting replacement, it would make the best fancy-party show bulbs. We spend a lot for decorations which we throw away next time. Those E-waste do pollute nature over time. A 3D Printed Bio-Bulb is significantly expensive, But the servicability, eco-friendly design would make small changes over time if accepted widely.
