Resin Curing Options

For Resin Curing, you can specify the following process setup options:

• Layer Resolution

• Layer Thickness

• Nesting Allowance

• Step Angle for True-Part Shape Nesting

• Number of Parts per Build Plate

• Base Plate: Support Structures Height

• Preprocessing Time

• Load and Splice Time

Layer Resolution

By default, layer thickness is specified by the cost model variable slaStandardLayerResolution (0.1mm in starting point VPEs). With this setup option, users can override the default, and select high resolution (specified by the cost model variable slaHighLayerResolution—0.05mm in starting point VPEs). See Cycle Time Formulas for Resin Curing.

Layer Thickness

By default, layer thickness is specified either by the cost model variable slaStandardLayerResolution (0.1mm in starting point VPEs) or the cost model variable slaHighLayerResolution (0.05mm in starting point VPEs), depending on the setting the option Layer Resolution (see below). With this option, users can override the default, and specify a thickness explicitly. See Cycle Time Formulas for Resin Curing.

Nesting Allowance

By default, the space allowance around nested parts is specified by the cost model variable nestingAllowance (5mm in starting point VPEs). Users can override the default nesting allowance with this setup option See Cycle Time Formulas for Resin Curing.

Step Angle for True-Part Shape Nesting

With true-part-shape nesting, the cost engine uses an internal algorithm that considers multiple candidate nesting arrangements using a variety of part orientations. By default, the various orientations differ by an angle specified by the cost model variable defaultUtilizationStepAngle (90° in starting point VPEs).

With this setup option, users can specify a step angle for the cost engine to use in order to generate additional candidate orientations—smaller nesting angles result in the consideration of a greater number of candidate nesting arrangements (which increases costing time, but may result in more efficient nesting).

Note that when the user specifies a step angle, the default candidate orientations are still included for consideration.

See Number of Parts for Resin Curing.

Number of Parts per Build Plate

By default, this is the maximum number of parts that can fit on the build platform, with a border around each part whose width is specified by the cost model variable nestingAllowance (5mm in starting point VPEs) or the setup option Nesting Allowance. With the setup option Number of Parts, users can override the default on a part-by-part basis, and specify a number of parts. See Number of Parts for Resin Curing.

Note that when you override the default with this setup option, the Material Nesting diagram can no longer be displayed.

Base Plate: Support Structures Height

By default, this is specified by the site variable basePlateOffset (10mm in starting point VPEs). Users can override the default with this setup option. See Machine Feasibility for Resin Curing, Cycle Time Formulas for Resin Curing, and Material Cost and Utilization for Resin Curing.

Note: if you use the setup option to override the default base height, this does not affect how the base is displayed in the Viewer and does not affect the values of support structure geometric properties displayed in the Geometric Cost Drivers pane. The override is used, however, in the determination of machine feasibility, cycle time, and material cost.

Preprocessing Time

By default, the time per part to orient the part or parts on the build platform is specified by the cost model variable slaPreprocessingTime (1200 seconds in starting point VPEs). Since the actual time may depend on how many parts are being built and how difficult they are to nest together, users can override the default on a part-by-part basis with this setup option. See Cycle Time Formulas for Resin Curing.

Load and Splice Time

This option controls the time to load the part model into the machine software and splice it into layers. By default, the time is specified by the cost model variable loadFileAndSpliceTime (0.25 hours minutes in starting point VPEs). Users can override the default with this option. See the formula for Amortized Batch Setup in Setup Formula for Resin Curing.
