5:1 GEAR RATIO
OmniaDrop has a 5:1 gear ratio using a planetary gear system which allows for a small footprint. This gear ratio needs less torque to drive the 1.75 mm or 3 mm filament. Less torque means the use of a lighter stepper motor. As a result, the overall weight of the extruder is decreased to a minimum.
DUAL DRIVE GEAR
To achieve a perfect grip two drive gears are used in the OmniaDrop. The main drive gear is screwed on the M5 bolt, which centres it and a grub screw locks the drive gear in place. The idler drive gear has two ball bearing and is being driven by the main drive gear.
Both drive gears are made from stainless steel and have sharp teeth that ensure a secure grip on the filament.
The M5 sleeves centre the M5 bolt using bearings.
COOLING BLOCK AND AIR FLOW
The cooling block is designed to vent the cooling air vertically upwards. This air flow system ensures that no breeze from the cooling block interferes with the printed part. This reduces the risk of warping.
SHORT FILAMENT PATH
To make the filament path as short as possible the cooling fins were moved to the side of the cooling block. A short and restricted filament path makes the extruder more reactive and gives the filament less options to kink. Additionally the dual drive gears grip the filament from both sides and pushes it evenly into the hotend.
The combination of a short filament path and the dual drive gears make the OmniaDrop a optimal solution to print any kind of flexible filament.
OmniaDrop uses a ring heater as a hotend. The advantages of a ring heater are the following:
An even power density around the nozzle
A better temperature distribution
A more responsive temperature measurement
A u-shaped or o-shaped part cooling fan can be located closer to the nozzle
PART COOLING FAN
By adding a part cooling fan, you get a more complete printing experience, because:
it is essential for some polymers, like PLA and TPU
it helps to print bridges and small features
it avoids curling on overhangs
E3D compatible nozzle system
E3D has probably the biggest selection of 3D printing nozzles on the market and are the market leader when it comes to hotends and nozzles. The OmniaDrop is compatible with the E3D V6 nozzle ecosystem, so that the nozzle diversity from E3D can be used.
The OmniaDrop comes with an original E3D 0.4mm brass nozzle.
