Safety Information
WARNINGS
The Nautilus 3D printer contains electronic, motorized, and heated parts. Always be aware of possible hazards
during operation. Keep your printer indoors in a dry, ventilated area and do not expose to rain or snow.
Burn Hazard
Never touch the nozzle, heater block, Print Surface, or build plate while hot, especially during printing. Make sure
heating to the tool and bed are turned off and internal parts have cooled completely before touching. Do not touch
recently extruded plastic, it is very hot and can stick to the skin causing burns. Avoid touching motors during or
after printing as they can also get hot.
Pinch Hazard
The Nautilus uses motorized, moving parts that can get caught on body parts, hair, jewelry or clothing. Do not
reach or put anything inside the printer during operation to avoid possible injury.
Fire Hazard
Never place flammable materials or any liquids on or near the printer while it is powered on. Electronics and
heated parts can pose a fire hazard when used improperly. Never cover the fan vents on your printer; doing so
can damage your printer and is a fire hazard.
Electric Shock Hazard
Always power down and unplug your Nautilus before connecting or disconnecting wires or accessing the
electronics enclosure. Never open the power supply; it contains parts that can cause harm when handled
improperly. Even when powered off, some power supply components pose a risk of electric shock. Place the
power cable so that it does not pose a tripping hazard and do not use a damaged power cable.
Print Surface
Do not print directly onto the Aluminum Build Plate, it can damage your printer and violate your warranty.
Keep Attended
Never leave your Nautilus unattended during operation or while powered on.
Appropriate Surface
Always keep your printer on a clear, stable, and level surface.
Age Warning
For users under the age of 18, adult supervision is strongly recommended. Small components or printed parts
may present a choking hazard.
Warranty Warning
The warranty included with the Nautilus covers manufacturer’s defects. Failure to observe the above warnings will
void your warranty. Operation instructions can be found in this user manual; failure to follow the instructions or
improper operation can damage your printer and void your warranty. Keep the packaging from your Nautilus; it
must be shipped in packaging approved by Hydra Research for all warranty claims.

other way. To flip the door, remove the screws holding
the hinges to the printer and swap them with the
placeholder screws on the other side.
ⓘ Do not overtighten the screws; you can strip
out the threads in the front panel
IO Panel
1. Panel USB Port: This Micro USB port is used for
updating the touch panel firmware.
2. Main USB Port: This USB-B port is used for tethered
printing. If you are unable to send files to the Nautilus
over a wireless network, you can connect the Nautilus
to a computer via this port and stream the print job
from Cura to your printer. The printer must not lose
connection to the computer for the duration of the job.
3. Power Switch: Used for powering the Nautilus ON
and OFF.
5
Top
1. Spool Holder: This is where you will place your spool
of 1.75 mm diameter filament. Ensure the free end of
the filament is at the front of the spool and pointing
downwards. The spool holder can accommodate a
spool up to 11 cm wide and 30 cm in diameter.
2. Active Ventilation: Ventilation port with a fan that will
turn ON when needed. Do not cover this vent.
3. Filament Insertion Point (FIP): There is a hole at the
top of the FIP lined with a PTFE tube. This is where
you will insert filament for printing. This part also
contains the switch for filament runout detection.
4. Passive Ventilation: Ventilation port, do not cover.
Back
1. Fume Vent: Two 80mm fan vent holes are located
behind the black plastic cover. The cover can be
unscrewed from the inside of the printer.
2. Power Inlet: This is where the power cord is plugged
into the Nautilus. Make sure to use a cord rated for
10A at 110W or better. The Nautilus can be configured
for 220W input rather easily, if you are interested
contact support.
3. Ethernet Port: This is where you connect an ethernet
cable for wired network connection if you opted for the
Ethernet version of the Nautilus. This port will be
covered if you purchased the WiFi version.
6
1.1.2 Interior
1. Tool Head: This is the part of the printer responsible
for heating and extruding the plastic filament. It
includes the extruder, Tool Cartridge, part cooling, and
bed probing systems.
2. Tool Cartridge: This part is removable by the white
tab sticking out on the right side of the tool head. (See
Section 1.4.1 for instructions on changing the Tool
Cartridge.)The Tool Cartridge is where the plastic
filament is melted and pushed out of the nozzle to
create 3D printed parts.
3. BLTouch (Bed Leveling) Probe: The BLTouch is the
white cylinder located behind the blower fan on the
front of the toolhead. A small plastic pin will drop down
from the BLTouch during the bed leveling procedure
and for a moment when the printer is powered ON.
4. Purge Bucket: The purge bucket captures excess
material purged from the nozzle during material
load/unload, at the beginning of each print, and when a
print is resumed after a pause. It also has a square,
orange, silicone pad used for wiping excess material
from the nozzle after a purge.
5. Build Plate: This is the heated aluminum plate that
moves up and down. The Print Surface is magnetically
attached to the build plate. Do not print directly on
the build plate, a Print Surface is always required.
6. Print Surface: The magnetically attached, flexible
Print Surface is what the print adheres to during
printing. This part can easily be switched for a
replacement or to use an alternative surface for
improved material adhesion.
7
1.2 Touch Screen UI Overview
The Nautilus uses a 7’’ touch screen for user control of the printer. Here you can start print jobs, monitor the
printer’s activity, load/unload material, and much more.
Tabs
The main interface is organized into four tabs that are always displayed at the bottom of the screen (highlighted in
green). The Nautilus defaults to the Control Tab on startup.
Each tab is explored in depth in the following section.
ⓘ The Nautilus uses the Duet open source CNC Control Platform. This platform was designed to work with as
many different configurations as possible so the Nautilus does not use everything that is available. Hydra
Research has streamlined the display configuration as much as possible, but you may run into the occasional
button that does not do anything on your Nautilus.
8
1.2.1 Control Tab
This Tab is opened upon startup of the Nautilus. This and the Print Tab will be where you spend most of your
time.
1. Printer Status: Displays the current printer status: Standby, Idle, or Printing.
2. Stop: The button acts as a software emergency stop. For all intents and purposes, it is like turning the
printer OFF and then back ON again. Uses this if you need to stop what the printer is doing urgently.
3. Heatbed ON/OFF: Turns the bed heater ON and OFF.
4. Hotend ON/OFF: Turns the hotend heater ON and OFF.
5. Current Heater Temperatures: The current temperature of the heaters on the Nautilus display in
Celcius.
●Red - the heater is ON and heating to the set active temperature.
●Green - the heater is OFF.
●Purple - heater fault. Check to ensure that the tool cartridge is properly inserted.
6. Active Heater Temperatures: The temperature the heaters will heat to when powered ON. Click the box
below the desired heater to manually adjust the active temperature.
7. Standby Heater Temperatures: The Nautilus does not use standby temperatures. The standby
temperature will usually be set the same as the active temperature unless the active temperature is set
manually by the user via the display or Duet Web Control. Click the box corresponding to the desired
heater to manually adjust the standby temperature.
8. Tool Head Position XYZ: The current XYZ position of the tool head within the printer.
9. Manual Homing: The far left of the homing buttons will home the X, Y, and Z axes all at once; the other
three homing buttons will home each of the axes individually. The Nautilus conducts homing routines
automatically, so you should rarely need to use these functions.
10. Print Jobs: This button opens the file menu for all the Print Jobs that have been uploaded to your printer.
This is where you select a job for printing.
9
11. Manual Movement: Opens manual axis jog control, allowing you to manually move the tool head and
build plate around. This is primarily used for maintenance and troubleshooting, but may be useful after
pausing a print job for inspecting or repairing prints.
● X moves the tool to the left (-) or the right (+).
● Y moves the tool to the front (-) or the back (+).
● Z moves the print surface up (-) or down (+).
12. Manual Extrude: Opens the manual extrusion control, allowing you to manually extrude or retract
material/filament. This is primarily used for maintenance and troubleshooting.
13. Macro Menu: Opens the Macro menu, which is home to the majority of the printer functions you will need
for setup and calibration. Four key macros are displayed in the top right corner for easy access.
14. Change Tool: Activate when you want to switch Tool Cartridges, or if you need to remove a Tool
Cartridge for maintenance.
15. Cooldown: Disables all heaters.
16. Material Load: Activates the material loading sequence.
17. Material Unload: Activates the material unloading sequence.
18. Bed Probe Reading: This is the reading from the bed probe, which is used during automatic bed level
compensation. You do not need to pay attention to this. It will display P0 when the probe is not triggered.
19. Automatic Bed Level Compensation: Manually initiate the automatic bed level compensation. This is
only needed for diagnostic/debugging purposes; the Nautilus initiates auto bed level compensation at the
beginning of every print job by default.

material before initiating this process. The process will reset the heater fault that is triggered when you
remove a Tool Cartridge.
●Cooldown: Turns OFF all heaters on the Nautilus.
●Material Load: Runs the material loading procedure. Make sure to preheat first; if you are changing
materials, always preheat for the higher of the two materials.
●Material Unload: Runs the material unloading procedure. Make sure to preheat first; if you are changing
materials, always preheat for the higher of the two materials.
●Power Loss Recovery: In the event of a power loss during a print job, this feature gives you the chance
to resume/save the job. This recovery relies on the power stored in capacitors to run some emergency
procedures before all power is lost. Additionally, jobs using materials that shrink significantly as they cool
may not be resumable if the printer has cooled before power loss recovery is initiated. Power loss
recovery is not guaranteed to work every time, and you should always visually inspect the Nautilus
and the part to make sure the part is still stuck to the Print Surface and everything looks in order
with the printer.
12
1.2.2 Print Tab
The Print Tab gives you control over the active print job. Here you can adjust print speed, printing temperature,
Z-offset, and view remaining time estimates.

1.4 Accessories
1.4.1 Tool Cartridges
Tool cartridges are quick and easy to change and offer a wide variety of printing capabilities from high detail to
rapid drafting.
Changing a Tool Cartridge
1. Before starting, make sure to unload filament.
2. On the Control tab select the Change Tool option from the menu in the top right.
3. Once the printer stops moving, a message will pop up prompting you to remove the installed Tool
Cartridge. Remove the Tool Cartridge by grabbing the white tab located on the right side of the print
head. Pull the tab to the right and up slightly. The Tool Cartridge is held in by both friction and a magnet
so it will take a little force to get it out.
⚠ CAUTION The Tool Cartridge may be HOT when you remove it, especially if it was just
heated to remove filament.
4. When you are ready, insert the new Tool Cartridge you want to use. Make sure the red line on the tool
cartridge is covered by the Tool Head. Press OK on the pop-up message to clear the heater fault that was
triggered by removing the previous tool. You are now ready to use your Nautilus.
The Tool Cartridge is properly installed when the red mark is covered
18
X Series Tool Cartridges
All X Series Tool Cartridges use genuine E3D Nozzle X, a specially designed, hardened steel nozzle plated with
nickel for abrasion resistance and a W2 coating for low friction and better flow properties. These nozzles are
suitable for all FFF materials supported on the Nautilus. They can withstand repeated use of abrasive
materials like carbon or glass fiber reinforced materials.
The thermal properties of Nozzle X often require a 5°C to 10°C temperature increase over what would be used for
a typical brass nozzle of the same nozzle diameter.
X 400 - all around
This is the standard, 0.4mm Tool Cartridge included with every Nautilus. It offers a great balance between
speed and detail. Additional Tool Cartridges for more specialized applications are sold separately.
X 800 - rapid drafting
This large, 0.8mm nozzle diameter Tool Cartridge excels at printing large parts quickly when there are no
small features and surface finish is less important. Due to the much thicker extrusion width, parts are
typically stronger when printed with this tool.
B Series Tool Cartridge
All B Series Tool Cartridges use genuine E3D Brass Nozzles. Brass’ thermal properties improve flow properties
allowing for faster printing speeds. These nozzles are only suitable for non-abrasive materials; repeated use of
abrasive materials will likely damage your nozzle.
B 250 - high detail
The 0.25mm Tool Cartridge can produce very high detail prints at the cost of greatly increased print times.
It is best used for smaller parts that have small features and need a smooth surface finish. Due to the thin
extrusion width, parts are typically weaker than those printed with larger nozzles.
