Stack Setup

Create Stack

There are two ways stacks can be arranged: Regular and Staggered. For either method, begin by selecting the part and clicking the create-stack-button.jpg button. Bases are recommended when creating any stack.

Regular

In this method, you will input X, Y, and Z counts for an array of stacked parts.

  1. Each part/combined set of parts acts as a cell of an array of parts that will duplicate struts and supports. Inputting a Count value will add that number of cells on the X, Y, or Z axis.
  2. Distance values indicate the distance between the centers of the parts.

  1. Use the Count and Distance inputs to create your stack.
    1. The image at the right shows a sample array of cells (dots). Notice that the stack preview shows your initial part/cell with its neighboring parts in X, Y and Z. Use the models in this preview to assist in visually nesting the parts.

    2. You can also drag each neighbor to control the distance between parts.  

    3. The blue dots indicate that the stacked parts will fit within the build area, while the red dots indicate they will not fit. This will be useful in determining how many total cells you can get on each axis.

    4. The stack will automatically ignore any part/cell that has a red dot.

  1. Click on Set Base, and then select the base file that was brought in earlier during build setup. This base will be printed directly on the print platform.
    1. The Margin field indicates the distance between the boundary of the part and the edge of the base.
      • A margin of 0 mm means that the base is the size of the part boundary. The larger the margin is, the smaller the base is.
      • Avoid having the bases intersect.
    2. The Clearance field indicates the distance between the bottom of the first-row parts and the base.
    3. An I-beam like connector piece will connect between the centroids of each part/base.
      • Notches are created in the middle of each base connector piece in case you would like to break up your stack pre- and post-curing in order to post-process parts according to your preferences.
      • Base connectors do not extend into the base itself.
      • You can use struts from the base to the part to create a more-rigid structure; but the struts connected to the base will not be replicated with each cell.
  2. Click on Set to apply the Stack generation.
  3. If any changes need to be made to the stack generation, such as spacing between parts, click on the stack and click on Create Stack to edit.

NOTE: When you re-edit a stack, any struts made on the stack will be erased

Staggering

In this method, you will still input X, Y, and Z counts for an array of stacked parts (Steps 1-3 in the Regular section, above). However, when you click Stagger, the cells will shift every other row.

  1. In the example at the right, the second row in the Y-direction is shifted half the distance between two of the parts in the X-direction. As you can see, for some geometries, this makes it easier to nest parts more closely.

  2. Using staggering will also allow you to add more stacks for medium-sized parts that are larger than 35 mm (in the Y-direction). Otherwise, you would only be able to create a stack in the X-direction.

  3. This feature can help you when cleaning printed stacks because the spacing in between parts allows for better flow for cleaning solvents to pass through.

Base

In this method, you will follow either the Regular or Staggering workflow; and you will add in a custom STL file that can be used as a base on which to stack your parts. This base will be printed directly on the print platform without supports.

  1. Click the Set Base button and select the STL file that was initially imported during build setup, or select one of the pre-installed 3D Sprint templates.
  2. The Margin field indicates the distance between the boundary of the part and the edge of the base.
    1. A margin of 0 mm means that the base is the size of the part boundary. The larger the margin is, the smaller the base is.

    2. Avoid having the bases intersect. 

  3. The Clearance field indicates the distance between the bottom of the first-row parts and the base.
  4. An I-beam like connector piece will connect between the centroids of each part/base.
    1. Notches are created in the middle of each base connector piece in case you would like to break up your stack before or after curing in order to post-process parts your way.

    2. Base connectors do not extend into the base itself.

    3. You can use struts from the base to the part to create a more-rigid structure; but the struts connected to the base will not be replicated with each cell.
