Part 3


Your HVAC system should perform at least six air exchanges per hour in the room where a Printer is located. You may wish to have a fume hood installed for your part-cleaning area. Ensure that your facility complies with all local and regional regulations regarding ventilation of vapors, dust, and other by-products of printing, cleaning and secondary processing.  Always refer to and follow the information on the SDS for your specific material.

Each Printer may be connected to external ventilation if desired. The extractor-duct connecter is 13 cm (5.1 in.) in diameter. The customer is responsible for arranging for any external ventilation system to be installed. 3D Systems will not service any part of such a system, including attaching the ducts to the Printer. To have your Modular system up and running with external ventilation as quickly as possible, it is recommended to have your ventilation provider install all duct work before your Modular system installation date. Then, on the date of installation, your ventilation provider should be present to connect the Modular system to the ventilation and ensure that it is working properly.


Air Cleanness

The room housing the Figure 4 system should be well-ventilated. Reasonable care should be taken to minimize dust and smoke which could contaminate the resin and cause deterioration of optical surfaces. Avoid temperature fluctuation. Since dust, smoke and temperature fluctuations can affect the performance of the machine and the quality of the parts, a restricted area with positive-pressure, filtered air flow is recommended. Avoid proximity to machine shop areas, or where milling, grinding, sanding debris, or insects can be introduced.


Standard fluorescent lamps with clear plastic diffusers are recommended to minimize ultraviolet exposure, which will negatively affect the Figure 4 resins. Sunlight, quartz-halogen lamps, and high-intensity incandescent lamps are not suitable; and UV-intensive lighting or ultraviolet exposure through windows should be avoided. UV filters are available for windows and exposed fluorescent lamps.

Door or Other Method of Preventing Access to Room

The site should be able to be isolated from other employees or personnel during installation or future service calls, as 3D Systems Service personnel may need to perform open-radiation operation of the machine. A separate room or area that can be closed to others is necessary. The system is safe and does not present hazards to properly trained personnel operating the system in accordance with our specifications. However, the system should be installed in an area that can be cleared of untrained personnel during service and maintenance of the machine due to optical-radiation safety requirements. An optical-radiation warning sign should be created and stuck to all doors during open-radiation operation by 3DS Service.

Network Access

Please pass off the following information to your network administrator:

There are two primary ways to connect your Modular system to your network, as described below. Take note of the setup for Port A and Port B on the Controller, as these ports are not interchangeable. Port A can only be used for internet input. Port B can only be used for connection to a dedicated printer LAN.

Common LAN

This will connect your Controller and Printers to your company's network.


Dedicated Printer LAN

This will allow for a dedicated network for your Modular system. This requires a DHCP server for setup and for DHCP printer configuration.


Networking Requirements and Necessary Equipment

Both the Controller and Printer include Ethernet interfaces, which can be connected to a Gigabit Ethernet network to offer network access to the Modular system. Ensure your networking equipment conforms to the following:

  • One or two Cat-5e/Cat-6 Ethernet outlets for the Controller, depending on which network setup you chose above
  • One Cat-5e/Cat-6 Ethernet outlet for each printer
  • Network ports 30301 – 30320 shall be available on the LAN to which the printers are connected.
  • 3D Sprint connection to Controller requires TCP port 5000 using REST API over HTTP.
  • 3D Connect™ requires connection to the internet via a gateway/NAT. All services use port 443 with encrypted connections

Each Printer is supplied with one 3m (10 ft) Ethernet cable. The customer is responsible for providing the following networking equipment:

  • One or two Ethernet cables for the Controller, depending on which network setup you chose above.
  • Networking equipment for your Controller and Printers

Other notes:

  • Static IP is supported for the Controller's ports A and B.
  • Proxy server is NOT supported for the Controller or Printers.
  • Static IP is supported for Printers - a DHCP server is required during setup to initially discover printers; then the printer IP addresses can be statically assigned via the Controller.

Telephone Service

Dedicated telephone lines are not required for normal operation of a Figure 4 system. You may wish to install a dedicated telephone line in the Figure 4 system installation area to facilitate discussions with 3D Systems Customer Service personnel while the machine is in operation, should the need arise.
