Part 1

Compressed Air

The Printer uses compressed air for its resin-tray tension arms. The compressed air connection can be shop air or a standalone compressor. It must have a minimum pressure of 70-110 psi of dry air. Consult 3D Systems if your air pressure does not go that high. Each Printer consumes less than 1 cfm. The compressed-air input is on the bottom-left of the back of each Printer. The air tubing must be either 9.5 mm or 6.4 mm (0.38 in. or 0.25 in.). The customer is responsible for providing all tubing, fittings, and connections for each printer. The fitting that connects to the printer must be a 3/8 in. connector. compressed-air-location.jpg

 

Floor/Area Surface

Floors and counter spaces in the Figure 4 work area should be non-porous and suitable for cleaning with solvents. The feet of each Printer must be on strong, stable concrete. The Printer should not straddle any floor seams. The maximum permissible floor incline is 2.5 cm/12 m (1 in/40 ft). The Controller may be on any desired flooring.

Floor Vibration and Shock

To ensure part quality and accuracy, choose a ground floor location for the Printer with a thick concrete pad, which will minimize vibration. Figure 4 equipment is slightly self-damping, and should not be affected by normal or incidental environmental vibration; however, the area should be isolated, either via location or some other physical or mechanical means, from any significant internal or external vibration sources such as heavy machinery, airplanes, or trains, which could cause unacceptable shock or vibration levels.

It is recommended that the amount of vibration/shock from the floor not exceed the SPIE 1991 VC standards of VC-A. This corresponds to a max floor velocity of 50 µm/sec over a 4-80Hz bandwidth.  Users are responsible for verifying the level of vibration in their facility.

Floor Capacity

The Controller weighs 98.5 kg (217.2 lbs). The Printer weighs 190.5 kg (420 lbs.), plus 2.5 kg (5.5 lbs.) with a full resin bottle installed. Refer to the Weights and Measurements Chart to determine the total weight of the equipment to be housed in your printing room to ensure that you do not exceed the maximum load-bearing capacity that your flooring can support.

Electrical Requirements

Electrical voltage requirements for the Printer:

100 - 240 VAC, 50/60 Hz., Single Phase, 10 A - does NOT need a dedicated circuit.

Electrical voltage requirements for the Controller:

100 - 240 VAC, 50/60 Hz., Single Phase, 10 A - does NOT need a dedicated circuit

Both the Controller and Printer draw the same power. You may have any combination of three Modular devices on one 15A circuit. For example:

Circuit 1: Controller, Printer, Aux. 1

Circuit 2: Aux. 2, Aux. 3, Aux. 4

These circuits should each be surge-protected. 3D Systems does not require the use of a UPS (Uninterruptible Power Supply) for the printer system. However, if you live in an area with frequent power surges/outages, a UPS would be useful. A UPS would prevent a build from crashing in the event of a brief power outage/surge. External circuits must conform to the double-insulation requirements for protection against electric shock in both normal- and single-fault conditions.

Ensure that the space you select for the Printer and Controller has enough power outlets reachable by the length of the power cord provided (2.3 m, 7.5 ft.) with each module. Use of an extension cord or power strip is not recommended.

If your power cord becomes damaged or lost, please ensure you order a replacement from 3D Systems for a power cord that is adequately rated for the machine. Do not replace the power cord with a cord that is not rated for the printer system.

Heat Dissipation

The Figure 4 Modular Printer is not expected to give off significant heat under normal operating conditions.
