points down to 50 micrometer diameter, which can pierce the skin with
enough force. Ensure hands are clear of the dispensing tips while the
machine is in operation.
2.1 Pinch, Crush and Sharp Surface Hazards
Smart Dispenser Heater
The Smart Dispenser contains a 20W heater that is congured to
maintain temperatures at or below 40°C (104°F), up to a maximum of
65°C (149°F). It has a built-in temperature monitoring and control system
as well as a thermal fuse. If the control system fails, this temperature
can reach 80°C (176°F). Take care when handling a
hot dispenser.

9.1 Software Updates and Network Connectivity
NOVA’s Application software and NOVA’s rmware update frequently to account for
feature updates, improvements, security, and any potential bug xes.
An internet connection is required to receive auto-updates to NOVA’s rmware. If you
are not able to regularly update either the rmware or software, it is possible that the
functionality may be compromised, and so we would ask that you ensure that you are
able to connect your machine to the internet. If you are not able to connect to the internet,
contact Voltera for assistance.
9.2 Suggested 3rd-Party Tools & Software
NOVA allows you to pattern exible or rigid substrates with your materials of choice.
However, oftentimes, you may need programs, processing equipment, or additional
materials to achieve the full functionality of your device. Based on your discretion, we
recommend making any arrangement necessary to access the following:
9.2.1 Consumables and Equipment
1. Curing Systems: Whether thermal, UV, or other, you should be able to post-process
your materials as necessary.
2. Functional Materials: While Voltera has a standard conductive ink and a variety
of substrates available, NOVA is designed to handle a wide range of uids and
substrates.
3. Luer-Lock Nozzles: If your application requires it, the Voltera Dispensing Module
can accept any Luer-Lock nozzle up to 30mm in total length.

tutorials readily available online which should allow you to quickly learn how to design
and export Gerber les, if required. Voltera also has Gerber export guides for EAGLE,
KiCad, and Altium available on the Voltera website.
9.3 Clean the Pressure Sensor When Not in Use
NOVA is intended to print high-quality patterns with a variety of screen-printable inks.
NOVA comes with three included Pressure Sensors. The Pressure Sensor must be
cleaned under the following conditions:
• Clean the sensor if it is removed from a cartridge for an extended period
(longer than a quick switch-over).
• Clean the sensor if you want to dispense a different material or a different batch
of the same material.
• Clean the sensor if a nozzle is removed for an extended period (longer than a quick
switch-over), exposing the material in the sensor to air.
Follow Voltera’s online Pressure Sensor Cleaning guide when cleaning the Pressure
Sensor. Never insert anything other than the included Nylon Cleaning Brush into the
Pressure Sensor.
Note: Never pressurize the sensor unless it is mounted on the Smart Dispenser.
