Neo450/800 Operation Manual
Introduction 7
1. Introduction
This operating manual describes the Neo®450 and Neo®800 3D printers.
The manual is a part of the product. Please read these instructions carefully before
operating the machine. Always observe all the safety guidelines in this manual. If
you have any questions regarding the contents of this manual, please contact RPS
(see the Customer Service section).
Keep the manual available for servicing, repairs, and product disposal. This manual
should accompany the product if ownership changes hands.
RPS reserves the right to update this operating manual at any time and without
notification.
Product Overview
The Neo450 and Neo800 are designed for building 3D models using the technique
of stereolithography.
Stereolithography is a form of 3D printing technology used for creating models,
prototypes, patterns, and production parts in a layer-by-layer process, using
photopolymerization, a process by which light causes chains of molecules to link
together, forming polymers. Those polymers then make up the body of a three-
dimensional solid.
The technical specifications of the product are summarised in the Technical
Specifications section of this manual.
Intended Use
Use the Neo450 and Neo800 only for their designed purpose as described above. Only
suitable accessories can be used with the product.
ID Plate
The ID plate which includes the
machine serial number is found on the
lower rear panel. A copy is also located
on the frame when the lower rear panel
is removed.

Neo450/800 Operation Manual
Principle of Operation 8
2. Principle of Operation
Stereolithography is an additive manufacturing process using a vat of liquid
ultraviolet (UV) curable photopolymer resin and a UV laser to build parts one layer at
a time. For each layer, the laser beam scans the cross-section of the parts on the
surface of the liquid resin. Exposure to the UV laser light solidifies the cross-section
and adheres it to the layer below.
After one complete layer has been scanned, the platform descends by a single layer
thickness, typically 0.1 mm. Then, a resin-filled blade moves across the vat applying
another layer of resin on the parts. On this new liquid surface, a next layer is
scanned, adhering to the previous layer.
The process continues until all layers of all parts have been scanned. After building,
parts are cleaned in a cleaning solution and then cured in a UV oven.

4. Safety
To reduce the risk of injury, read these instructions carefully before using the Neo450
or Neo800. Always observe the safety guidelines listed in this manual. Protection of
the user is impaired if safety instructions are ignored, or used in a manner not
specified in this document.
The safety and warning notices in this manual are indicated by the following symbols:
Instructions that may affect a person’s health.
Instructions that:
•Warn of damage that may occur
•Warn of reduced product performance
•Recommend best practice

Laser Safety
Laser Specification
During normal operation, and with all panels installed the Neo450 and Neo800 are
Class I laser products to BS EN 60825-1:2014. Class I products are not considered
harmful and require no special safety precautions under normal operating
conditions. The laser beam is completely confined. The viewing windows block the
UV laser radiation from exposure outside of the device.
Stray radiation can also be dangerous. This radiation can cause fire or explosion and
the generation of toxic gases or vapours.
The observance of laser safety must be ensured at all times.
Never stare directly into a laser beam, nor into any beam reflection, whether
diffused or from a highly reflective surface.
Safety regulations may differ from country to country. The customer bears
sole responsibility for compliance with all applicable safety regulations of
their respective regulatory jurisdiction.
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure

Neo450/800 Operation Manual
Safety 12
Interlock System
Safety interlock sensors on each door and lower front panel protect the user from
possible UV laser radiation exposure. By opening a door or removing the front panel
the interlock system is triggered, closing the safety shutter which physically blocks
the output of the laser.
The top cover(s) of Neo450 and Neo800 employ an additional interlock which ensures
that the laser cannot be switched on when the top cover remains open.
If the interlock system is active the user will be unable to action any move operation,
and will be unable to start a job. If the interlock system is triggered while the machine
is performing an operation or job, the shutter will close, the laser emissions will be
ceased, and other activity halted.
The interlock system may be defeated by trained service personnel in order to perform
onsite service procedures.
The Titanium User Interface indicates interlock status:
If any of the interlocks are defeated, the Neo450 and Neo800 become Class
IV devices. Eye damage can occur by looking directly into the beam or by
viewing any type of beam reflection.
Interlocks are to be defeated only by trained personnel when needed during
service procedures.
A user must not operate a machine which is displaying the Interlock Defeated
symbol.

Electrical Safety
Please refer to the Technical Specification section for electric supply specification.
Always observe the following guidelines:
Installation of the machine must not restrict the isolation switch at the rear of
the Neo. Please refer to the Site Preparation Guide.
Do not overload a wall outlet, extension cord or adapter as this may result in
an electric fire or shock.
Never use an inadequate rated power cord to supply the device.
Inspect the power cord for damage before use.
Do not bend or twist the power cord.
Do not touch the power plug with wet hands.
Do not remove covers as hazardous voltages are present inside.

Material Safety
The Neo range is an open material platform. Any commercially available 355 nm
photopolymer materials, more commonly referred to as resin, can be processed.
Please ensure you have the necessary safe handling guidelines from your material
supplier.
General Material Handling Safety Guidelines
Operating Conditions
When operating the Neo450 or Neo800, always observe the following guidelines:
•The ventilation ducts must be left uncovered to allow proper airflow into the
Neo.
•The Neo should not be exposed to liquids other than to top up the vat with
resin.
•Wipe off any resin spills immediately using a cloth dampened with isopropanol.
•Temperature range: 20-23 ˚C
•Maximum temperature rate change: +/- 1 °C/hour
•Relative humidity: 20-50 % (non-condensing)
•Protect the Neo from dust and corrosive vapours to avoid damage to the
mirrors, optics, and electronics.
IRRITANT: Always wear chemical-resistant gloves, goggles, and protective
clothing when handling material, containers, or partially cured parts.
100% nitrile gloves offer best hand protection. Latex gloves are not
chemically resistant, and are not recommended.
Always ensure good ventilation, and avoid breathing vapours
Wipe-up any spills immediately, using paper towel dampened with
isopropanol (IPA)
Use soap and cold water to wash material in contact with skin. Never use IPA
or hot water, as this will increase absorption.
Use care when handling IPA used for cleaning materials. IPA is highly
flammable.

Neo450/800 Operation Manual
Safety 20
•Avoid strong electromagnetic fields and static electricity. These can damage
the electronics of the interface and amplifier boards.
•For further details please refer to the Technical Specification section at the
rear of the manual.
