The LILY Kit Lite is a downsized version of our original LILY Kit. The core technology with our patent-pending extrusion zone design, the self-developed dispenser PCB, and the overall design, will be the same. We downsized some of the motors and other components to offer approx. 80% of the performance at 59%of the original price.
The modular mounting plates with M4 x 0.7 threaded holes, let you bolt-on the extruder to your 3D printer carriage. The orientation of the U-shaped brackets can be individually changed, which delivers 3 different vertical hole distances (34, 47.7, 61.4 mm).
The next step is to wire the LILY Pellet Extruder to your 3D printer. We recommend using the included MOSFET to connect the 80W heating cartridge. The Auto Pellet Dispenser needs no connection with the 3D printer. It works autonomously via its own PCB and power supply.
For the LILY Kit to transfer material and signals automatically a few last connections are needed. The IR level sensor of the extruder needs to go to the dispenser. Then Connect the PE feeding hose to the extruder and the dispenser. Last but not least connect the power cord of the dispenser.
Follow the detailed instructions in the documentation to adapt the firmware (Marlin, Repetier, Smoothie) and slicer settings to pellet 3D printing. The LILY Kit works with standard .gcode files.

Super Volcano 80W Heater
6 mm diameter, standard Super Volcano heating cartridge. Easy to replace and/or exchange in order to adapt to 12 V and 24 V.
Low Current Stepper Motor
The geared 34 mm LDO stepper motor (19:1) delivers 5.2 Nm of torque while only using 1.0 A. This guarantees compatibility with your 3D printer board.
M6 threaded Nozzles
The LILY Pellet Extruder Lite is designed to work with M6 threaded nozzle. Large diameter nozzles - 0.8,1.0, 2.0 mm are included.
The LILY Kit Lite uses the same patent-pending extrusion screw than the original LILY Kit. Thus it can handle industrial pellets, chunks/flakes from shredded waste plastic and extrude in color by using colorants.
IR Feedstock Level Sensor
The integrated IR feedstock level sensor in the hopper triggers automatically the Auto Pellet Dispenser, when the extruder needs more pellets.
Dual Metal Extrusion Zone
For the screw, barrel and hopper we opted for 2 different metals. The different heat conductivity of the metals helps to avoid clogging.
Axial Pellet Cooling Fans
2 x brushless fans (24 or 12 V) prevent clogging of pellets at the entrance of the hopper by creating a cross airflow in the reservoir.
Duralumin mounting plates with M4 x 0.7 threaded holes, let you bolt-on the extruder to your 3D printer carriage. The orientation of U-shaped brackets can be individually changed, which delivers 3 different configurations of vertical hole distances (34, 47.7, 61.4 mm).
Electronic Brain
The independent electronic brain of the Auto pellet Dispenser is our self -developed, open-source and ATMEGA based PCB (ATMEGA32U4-AU)
NEMA 17 Pancake
The NEMA 17 stepper motor allows for precise movements, which ensures controlled dispensing of pellets into the conveyor airflow. This ensures reliable and consistent feedstock supply to the extruder.
Long Distance Feedstock Travel
The 7.5 Kpa and 240 L/min max capacity of the DC blower generates an air flow strong enough to carry granule feedstock across a 1.5m distance between dispenser and extruder or through a up to 2.5m long feeding tube.
The Auto Pellet Dispenser supplies granule feedstock, whenever the LILY Pellet Extruder needs it. For this to work fully automatically an IR level sensor can be connected to the dispenser PCB. For the LILY Pellet Extruder our open-source PCB code computes the IR level sensor signals and efficiently controls the feeding sequence. The granule feedstock is rapidly supplied in bursts of few seconds, which allows for the system to switch to stand by mode between opeartions.
