SINTERIT Lisa X SLS 3D Printer

Please read the full instruction manual before putting the device into service.

The short manual provides only a basic overview of the device and its general use. It will guide you throughout the entire printing process. For detailed information and to learn more about specific features of your printer, please view the full manual at www.sinterit.com/support-page/. Sinterit disclaims any liability resulting from the lack of knowledge provided in the full manual.
Listed below are the conventional symbols used throughout the guide and basic safety rules for working with the machine. They indicate warnings or carry important notices, so as to protect the user, any bystanders and objects in the vicinity. They also provide the basic guidelines for proper and safe operation of the device.

SAFETY INSTRUCTION

WARNING!
An inevitably dangerous situation, potentially resulting in bodily harm or even death. The initiation, refusal or neglect to carry out the specified procedure, or carrying it out in a careless or negligent manner, may cause potential injury to the user or any bystanders.
ATTENTION!
The initiation, refusal or neglect to carry out the specified procedure, or carrying it out in a careless or negligent manner, may cause property damage and/or injury to person(s) operating the device and/or those located in its vicinity.
DANGER!
Risk of electric shock. An inevitably dangerous situation, potentially resulting in severe burns or even death. Before operating any electric device, it is important to understand the dangers of electricity and the proper procedures to mitigate them, as well as the steps necessary to perform in case of a related emergency.
WARNING!
Pressurized gas! Danger of asphyxiation!
The gas canister could potentially become unsealed – the intert gas is a simple asphyxiant (displaces oxygen from the air). Low oxygen levels may result in the loss of consciousness and ultimately death, if not correctly mitigated. The immediate symptoms include shallow or labored breathing, migraines and vertigo; in critical concentrations, the afflicted may experience nausea, weakness, long-term loss of consciousness and, ultimately, complete asphyxiation.
ATTENTION!
IR laser radiation. The laser emits infrared (IR) light, which is not visible to the naked eye. It is important to avoid skin and eye contact. Direct eye exposure to the laser beam may result in deterioration of eyesight or even blindness. It is forbidden to observe the beam with optical instruments (i.e. looking glass, lenses). Additionally, direct skin exposure might result in burns.
ATTENTION!
High temperature – do not touch! Contact with the heating elements can result in severe burns.
ATTENTION!
Mind the moving parts, which could potentially crush limbs.
ATTENTION!
Mind the sharp edges, which could result in cuts, especially to the hands.
ATTENTION!
Beware of high intensity light.
DANGER!
Fire and/or explosion hazard!
Mitigate the risk of combustion; the powder dust is extremely flammable!
ATTENTION!
Risk of electric shock. The device is equipped with a ground. It is necessary to observe the precautions described in the manual as well as all the safety warnings and notices posted on the device itself.
STOP!
The described action is strictly forbidden.
ATTENTION!
It is necessary to wear personal protection: clothing, eye wear, face mask and gloves. It is absolutely crucial while performing any work with the powder, in order to prevent potential injuries.
ATTENTION!
Antistatic clothing and footwear required. They are absolutely necessary while working with powder.
IMPORTANT!
Before attempting the described action, please consult the instruction manual.
