This User Manual contains important safety directions that should be followed during

installation and operation of the Nova3D ELFIN. It also mentions situations which require

special attention and includes warnings against negligence and misuse that could cause damage

or injuries.

Always read the safety data sheets available at:

http://www.nova3dprinter.com/material.html. There are a source of basic information and

safety procedures for the materials you bought. It is essential to regularly update the firmware

to avoid any kind of failures.

Visit our website: http://www.nova3dprinter.com/ to learn about the latest news and

updates.

Printing process with the Nova3D ELFIN requires using liquid photosensitive resin which

in a liquid form is low toxic and may cause allergic reactions. Therefore, you must protect your

skin and eyes when using the printer by wearing safety gloves and glasses. Proper ventilation is

required in the print room.

It is also extremely important to avoid spilling the resin on the printer and its surroundings

while operating the printer, filling the vat and removing prints from the platform. Ensure that

the printer is level and keep it on a stable surface. Do not remove the UV cover during the

printing process.

Do not leave the machine unattended during the printing process ,check it periodically for

proper functioning in order to avoid potential accidents or breakdowns. Turn off the printer and

empty the resin vat once the printing process is finished.

Keep the printer away from heat sources, flammable materials, equipment emitting

radiation, sources of fire, humidity, water and other liquids. To prevent any inadvertent use,

keep the device out of reach of children and animals. It is forbidden to drop or shake the printer

as it may cause breakdowns. The equipment is not intended for use in a potentially explosive

environment.

The Manufacturer strongly recommends setting up a special room dedicated only to 3D

printing. The room should be as free of daylight as possible and properly ventilated. It is

important to avoid situations in which liquid resin is exposed to daylight.

Workplace Health and Safety

Keep the workplace clean. Containers with resin should be tightly closed and kept in a dark

place. The device should be configured according to its intended purpose. Improper

configuration may cause defective operation which may lead to damage of the device. Food

and beverages should be kept away from both the 3D printer and the 3D printed objects. Do not

put any objects under the UV cover. While operating the Nova3D ELFIN, all measures

regarding health and safety that are provided in this User Manual as well as in separate

regulations should be taken into account.

Electrical Safety

Nova 3D printers have been tested for compliance with Low Voltage Directive. In order to

ensure the highest safety standards, including protection against short circuit, overload,

overvoltage and printer overheating, do not attempt to modify the printer and do not use

unauthorized electronic replacement parts other than those recommended by the Manufacturer.

Replace electronic units according to the instructions and be particularly careful while

using the tools supplied with the printer. Before plugging the power cable into the outlet, make

sure that the power supply voltage in the outlet matches the required value provided on the

nameplate at the back of the printer.

Avoid overloading the outlet with too many devices. The printer must connect to the

ground properly. Always make sure that the ground complies with local and national

regulations. Do not expose the device to rain and humidity. While filling the vat with resin, be

careful not to spill the resin outside the vat. Liquid that enters the inside of the device increases

the risk of an electric shock. All maintenance and repair work should be carried out while the

device is off and unplugged. Modifications such as soldering of electronic subunits are

forbidden.

Mechanical Safety

The Nova3D ELFIN has movable components, such as the build platform and the Z-axis.

Therefore, it is forbidden to reach into the printer or put anything inside the printer when it is

running, about to start running or at rest. Tools and accessories delivered with the printer should

be used with special care. Improper use may cause serious injuries. While following

post-processing procedures, wear safety gloves and glasses to avoid injuries that may be cause

by sharp edges and fragile elements of models. A finished print must be removed from the

platform outside the printer, after both the platform and the model have been cleaned from

uncured resin in a liquid detergent. To avoid injuries, be particularly careful while removing

prints from the platform. Always wear gloves and glasses. The FEP film that is installed in the

resin vat is very thin and fragile, therefore, special care should be taken when cleaning,

installing and disassembling the vat.

Risk of Burns

There is no risk of burns as all components working in high temperatures are enclosed，

but don’t touch the inside parts. Constructional modifications of the printer’s operating

temperature are not permitted as it may cause serious injuries or bring damage to the device.

Nova3D devices must be stored between 18 and 35° C [64 - 95° F]. The storage space should

be free of moisture and other extreme conditions.

Transport Instructions:

When stacking several devices on a pallet, follow the instructions provided on the

packaging. Once device may weigh more than 10 kg [22 lb]. It is therefore advisable to provide

safe pallet storage but not higher than 1.7 m [5’7’’]. It should be noted that the packages must

not project beyond the outline of the pallet. Packages stacked on the pallet should be then

bound together and wrapped in foil. The pallet prepared as above can be then forwarded to the

shipping company.

Pallet stacking and destacking should be carried out by two people. The package with the

device should be lifted or moved using special handles.

Electromagnetic Compatibility (EMC)

Nova3D printer complies with Part 15 of the FCC rules. Its operation is subject to the

following two conditions: this device may not cause harmful interference, and this device must

accept any interference received, including interference that may cause undesired operation.

The printer generates, uses, and can radiate radio frequency energy and, if not installed and

used in accordance with the following User Manual, may cause harmful interference to radio

communications.

1. Learn More About the Nova3D ELFIN

Nova3D ELFIN is a 3D printer which, together with NovaMaker and dedicated materials,

constitutes the whole 3D printing ecosystem. This device makes it possible to turn digital,

three-dimensional projects into reality using the UV LCD technology which relies on curing

liquid photopolymer layer after layer. The UV LCD technology involves projecting an image of

a layer on the transparent underside of the vat with liquid resin and curing the layer using

backlight from a UV lamp. After each layer is cured, the lamp pauses to operate. During the

pause, the layer solidifies and the platform rises and lowers itself so the resin is equally

distributed in the vat. The printer is equipped with an LCD screen which is responsible for

projecting successive layers and masking the UV light. Thanks to that, the resin that is outside

the image of a layer is not cured and can be used to print the rest of the model. The printer

allows users to print multiple parts at the same time without affecting the accuracy and printing

speed. Once the printing process is finished, the model has to be post-processed in two steps.

The first step involves cleaning the print from residues of uncured resin in a liquid detergent,

whereas the second step involves additional UV curing so that the object acquires its intended

properties.

Everything begins with preparing a model. The work on the project can start in any

program which creates 3D models and generates .stl, .obj files. These are the standard file

formats supported by most types of modeling software - the model is saved as a set of

three-dimensional triangles (triangle mesh). The next step is to open the .stl file (or .obj、.nmk

files) in NovaMaker - the program created specifically for Nova3D devices. NovaMaker

prepares the model by slicing it into individual layers and saving it as a .cws file. NovaMaker

also allows you to choose the material type to be used for the model and to adjust the necessary

print settings, such as layer thickness, layer exposure time, exposure off time or how many

support structures should be generated. The file is then ready to be printed.

To start the printing process, turn on the printer, prepare the material which corresponds

with the one you have chosen in NovaMaker and carefully fill up the vat with an appropriate

amount of liquid resin. While working with the Nova3D ELFIN, you can start, stop and pause

the printing process in NovaMaker. Once your file is prepared, you can transfer it from

NovaMaker to the printer’s storage in two ways. You can either save the file on a USB flash

drive and plug it into the port at the back of the device or transfer the file from NovaMaker

over Wi-Fi / Ethernet cable. In addition, NovaMaker allows you to add several printers to the

panel and create a network of devices. This solution makes it possible to produce 3D models in

a small series and manage the whole process from the screen of your computer. Each printer

can still be operated using the touch screen at the front. It is also possible to change all settings

related to exposure time of particular elements of the model directly during the printing

process.
