OmniaDrop Pre-Order

 

The OmniaDrop comes as a kit in two different versions. The standard version uses two mounting holes which are 60 mm apart. These mounting holes can be used to attach the OmniaDrop extruder to your 3D printer carriage. The second version is a Prusa edition which was developed to be a drop-in replacement for the standard extruder on the Prusa i3 MK3. 

A third option is to use the files of the OmniaDrop extruder and adapt it to your specific carriage. With the purchase of the OmniaDrop you get a link to the files.

 

Update 15.01.2020: Most of the parts are now in stock. The heatbreak did not arrive with the specifications required and our supplier was not able to manufacture these to our specifications. As a result we needed to find a new supplier. The shipping date for OmniaDrop pre-orders is now the 20.02.2020, If you want/need further information on your pre-order do hot hestiate to contact us.

 

Which filament diameter is better for flexible filaments?

Generally speaking, 3 mm flexible filament cannot kink in the extruder, while 1.75 mm flexible filament can. This is just due to the physical size of the 1.75mm filament. As a result, it is easier to extrude more filament per time with a 3 mm flexible filament than with a 1.75 mm filament. However, the print quality will always suffer if you print too fast regardless of filament diameter and filament material. Just work with that filament diameter you feel most comfortable with. Just be patient with flexible filaments and you will not see any big issues with either filament diameter.

 

Are there any differences between the 3 mm Filament and the 1.75 mm Filament version? 

The only difference between these two versions is the stepper motor and drive gears.

 

1.75 mm Nema 17 stepper motor

Body length: 20mm 

Weight: 140 gr.

Motor Type: Bipolar Stepper

Step Angle: 1.8 deg

Holding Torque: 13 Ncm (18.4 oz.in)

Rated Current/phase: 1.0A

Voltage: 3.5V

Phase Resistance: 3.5ohms

Inductance: 4.5mH ± 20%(1KHz)

 

3 mm Nema 17 stepper motor 

Body length: 34mm 

Weight: 230 gr.

Motor Type: Bipolar Stepper

Step Angle: 1.8 deg

Holding Torque: 22Ncm(31oz.in)

Rated Current/phase: 1.33A

Voltage: 2.8V

Phase Resistance: 2.1ohms

Inductance: 2.5mH ± 20%(1KHz)

 

It is possible to use the smaller Nema 17 motor with a 3 mm filament however, you will run into issues when extruding a lot of filament, for instance with a 0.8 mm nozzle printing at 0.4 mm layer heights. If you wish to use a the smaller Nema 17 with the 3 mm version, write that in the comment section when ordering.

 

What are the components of the OmniaDrop made of?

All the printed parts are printed with PETG, except the Planet-Gears. The Planet-Gears are printed in Igus Iglidur I150 which is a tribo-filament with high abrasion resistance. All the metal parts (except the cooling block and nozzle) like screws and hobbed gears are made from stainless steel. The cooling block is made from an aluminium alloy with a high heat transfer coefficient. The sun gear on the Nema 17 stepper motor is made from brass. 

 

Why is the OmniaDrop Prusa edition only available with 24V?

The OmniaDrop Prusa edition was developed for the original Prusa MK3, this why the OmniaDrop Prusa edition comes with a 24V ring heater and two 5V 3-pin blower fans. If you have a Prusa clone or Prusa MK2 that runs on 12V or 24V, then write that in the comment section when ordering and you will get the ring heater and blower fans in that voltage. 

 

Are there any downsides compared to the stock Prusa extruder?

The OmniaDrop extruder was built to optimally print flexible filaments and was not built to fit a certain printer. As a result, due to the design constraints on the Prusa MK3 printer you will lose 17.5 mm on the Y-axis and 7.5 mm on the X-axis however, this still leaves you with a print area of 242.5 mm in X and 192.5 mm in Y.

Currently the OmniaDrop does not come with a filament sensor, so you will not be able to use the filament sensor on your Prusa. The filament sensor on the Prusa could not be converted to fit the OmniaDrop extruder.

This is however a project for the future.

 

Can you use a BLTouch on the OmniaDrop?

Yes, there is a BLTouch mounting option avaiable for the OmniaDrop extruder. When you order just write BLTouch in the comment section of your order and you will get the OmniaDrop with a BLTouch mount.
