Site Selection - Post-Processing Equipment

Locating the post-processing equipment depends in large part on which resin types you will be using. The following abbreviated site specifications are recommended for your post-processing equipment.

Space and Location Selection

You may choose to locate the part-washing, drying, and curing stations in the same room as the printer system, or in a room adjoining the system.

NOTE: 3D Systems does not provide part-washing stations or drying equipment.

 

With either option, please consider the following:

  1. The further the distance the printed part is moved from a Printer to the post-processing area, the longer the opportunity for the part to get damaged by dropping, bumping into objects, and other environmental factors.
  2. The further the distance the printed part is moved, also longer is the opportunity for uncured resin to drip onto the floor. If floors are porous, such as carpeting or some tiles, they can absorb the spilled resin and would need to be professionally cleaned or replaced.

Refer to Optimal Site Layout for a suggestion for overall layout. Refer to the Weights and Measures Charts for weights and measurements of the LC-3DPrint Box and Figure 4 UV Curing Unit 350. Consider the following additional specifications when selecting the location for your post-processing equipment.

Figure 4 UV Curing Unit 350

Choose this as your UV curing solution if you plan to print parts over 200mm (7.9 in.) tall, or if you wish to have a higher capacity for curing many parts at once. This unit has the capacity to cure a part up to 350 mm (13.8 in) tall, or to cure many parts simultaneously on a multi-tier rack with glass shelves. 350mm is the maximum height of a part on the Figure 4 Modular system.

NextDent LC-3DPrint Box

Choose this as your UV curing solution if you plan to print parts less than 200mm (7.9 in.) tall, or if you do not need the higher capacity of the UV Curing Unit 350. This unit has one tier and cannot cure as many parts at a time as the UV Curing Unit 350.

Floor Surfaces

Flooring under a curing unit should be non-porous and suitable for cleaning with solvents. Carpeted floors are not recommended.

Electrical Requirements

Figure 4 UV Curing Unit 350

Power configuration:

120-240 V~, 50/60Hz, 3.5 A

Electrical power for the UV Curing Unit 350 must be on a surge-protected circuit. A UPS, while not required, is recommended in areas with frequent power fluctuations, as surges and spikes can damage electronic components and power loss can damage the unit.

If your facility's voltage is 100V~, you must purchase a step-down transformer to plug the unit into.

NextDent LC-3DPrint Box

Power configuration: 110V/240V – 50/60Hz – 2.6A/1.3A

Electrical power for the LC-3DPrint Box must be on a surge-protected circuit. A UPS, while not required, is recommended in areas with frequent power fluctuations, as surges and spikes can damage electronic components and power loss can damage the unit.

Ultrasonic Cleaner

Power configuration: An example of the power configuration for a consumer-grade ultrasonic cleaner is 120W at 40,000Hz. There are ultrasonic cleaners of many sizes, from around 2.5L (0.66 gal.) to upwards of 757L (200 gal.) Determine which size ultrasonic cleaner is best for your needs.

You must also get an ultrasonic cleaner that is rated to use flammable solvents like IPA. Failure to do so could present a fire hazard.

Electrical power for an ultrasonic cleaner must be on a surge-protected circuit, particularly for a bigger (not desktop) cleaner. A UPS, while not required, is recommended in areas with frequent power fluctuations, as surges and spikes can damage electronic components and power loss can damage the unit.

Part Cleaning

Please see the Post-Processing Guide section Cleaning Parts Printed with Figure 4 Resins for a list of required tools and equipment for post-processing printed parts.

Connection to AC Power

The Figure 4 UV Curing Unit 350 is designed to plug into a standard power outlet in different countries.

The LC-3DPrint Box is designed to plug into a standard power outlet in different countries.

Smaller ultrasonic cleaners will also plug into standard wall outlets; bigger ones, however, may require a custom power outlet.

Ventilation (Ductwork)

The Figure 4 UV Curing Unit 350 may be vented outside via a vent hood over the machine if required by your facility; however, ventilation is not required by 3D Systems. Contact your Facilities Manager for your requirements.

The NextDent LC-3DPrint Box may be vented outside via a vent hood over the machine if required by your facility; however, ventilation is not required by 3D Systems. Contact your Facilities Manager for your requirements.

CAUTION: Never disconnect a ducting system that is connected to an external extraction system.
