The following Use and Maintenance Manual describes the dedicated operations for correct and safe operation of Sharebot MetalOne. All the tasks described are aimed at Machine Operators. MetalOne has the following features: - Technology: LPBF - Laser Powder Bed Fusion - Print area: X side: 30 to 350mm Y side: from 30 to 350mm Z side: from 30 to 500mm - Inert gas: Argon or Nitrogen - Required inert gas pressure: between 3-7bar; reduced in the machine to 0.4bar - Required inert gas flow rate: 1-30l/min depending on the processing phase MetalOne - User Manual © Sharebot srl via Montello 18 23895 Nibionno...

MetalOne complies with the following safety regulations: Page 6 of 73 MetalOne - User Manual © Sharebot srl via Montello 18 23895 Nibionno (LC) Italia - Codice Fiscale, Partita IVA IT 03482570136

The safety systems adopted in MetalOne are implemented to guarantee the safety of the operator in compliance with the above regulations. Once started the machine has two states: In which the control system is active but all systems that can give rise to safety problems are not powered, in particular the power supply is not connected to: - laser source; - inert gas recirculation pump; - solenoid valves for supplying the inert gas present in the machine (the external line remains in any case under pressure); Page 7 of 73 MetalOne - User Manual © Sharebot srl via Montello 18 23895 Nibionno (LC)...

Status ARMED In which all systems will be active and ready for use. The ARMED state can only be reached by completely closing the emergency circuit and pressing the activation button with the silk-screen "1". On the front panel of MetalOne there are: 1 - Machine control interface It allows the management of the machinery, requests confirmation before executing the operator’s commands and signals with colored bands the status of the machine if armed or disarmed; 2 – Machine “ARMED” and “DISARMED” control It allows you to arm the machine by pressing the green button and to disarm it, or reset an...

4 - Print compartment door safety control When the front door of the print compartment is open, the printer cannot be armed. If the door is opened while the printer is armed, it causes the opening of the emergency circuit and therefore disarming. Warning: The piston and recoater motors remain active to allow process preparation operations. The personal protective equipment (PPE) required to work with metal powders are as follows: All of the items listed above must be available to each employee before the machine and materials arrive on site. All PPE must remain in place. A place for the storage...

The preparation of the premises and the safety features required by the machine is left to the customer. The machine is expected to be installed in a closed room with adequate lighting. To protect against the danger of asphyxiation, a residual oxygen detector with alarm must be set up in the room that houses the machine. Provide extensive signs of mechanical risk. The temperature of the...

In addition to the minimum measurements for positioning the machine and opening the front door, provide adequate space for movement. Minimum dimensions of the room (L x W x H): 3000 x 4000 x 2700mm. Operator work areas The machine operator must be able to move freely around it and safely perform all the operations described in this manual. Preparing for installation Use this guide to prepare the structure for the installation of the MetalOne printer. Once you have satisfied the requirements for each section of this guide, contact [email protected] before proceeding with the unboxing...

Oxygen monitoring system ATEX vacuum cleaner Installations must have an explosion-proof vacuum cleaner with wet separator certified for ATEX 21 / NEC, class II, group E. Oxygen monitoring system For safety when using inert gases (Argon and / or Nitrogen), it is necessary to install an oxygen monitoring system in the air of the room hosting the MetalOne printer. The oxygen monitoring sensor must be installed at a height of approximately 600mm (24 inches) from the floor. Storage of reactive metal powders To store reactive metal powder in your facility: Use closed containers. Closed containers prevent...

stored powder catches fire. In the ideal situation, the large quantities of powders are stored in a suitable separate building, away from the production environment. Room ventilation MetalOne processes take place in inert atmosphere inside the process chamber. During the preparation and loading/unloading operations of the machine, the inert gas is released into the environment. Therefore in small rooms ventilation is essential. During the loading and unloading of the machine, the powder particles are dispersed in the air. The presence of metal powders in the air of the work environment is dangerous...
