AdvancedTek AE Pro Tips: Adaptive Slice for FDM

AdvancedTek AE Pro Tips: GrabCAD Print Adaptive Slicing
October 16, 2020 News

GrabCAD Print 1.45 was released in late August 2020 and with it came a brand-new feature for FDM users called Adaptive Slice. This feature enables users of select FDM systems to greatly increase their print speeds by increasing the layer thickness of vertical walls while still preserving the finer resolution layer height on gradually curved surfaces.

What is Adaptive Slice?

Adaptive Slice is an automated feature in the software’s slicing process that if enabled while selecting your layer slice (.007” or .010”), will automatically apply your selected layer thickness to the gradually curved features of your part (e.g., holes, chamfers, fillets, domes, etc.), and its slightly thicker layer slice “pair” (.010” or .013”) to the remainder of the part (i.e., straight vertical walls).

What are these Adaptive Slice “pairs”? Adaptive Slice works with any FDM material but only in the following two layer slice “pairs”:

  • .007” and .010”
  • .010” and .013”

This means when you select .007” slice and enable Adaptive Slice, all gradually curved surfaces will print in .007” layers and your vertical walls and steeper surfaces will print in its paired .010” layers. The same goes for .010” slice pairing with .013” slice.

Printing in Adaptive Slice will result in a faster build time compared to printing the entire part in the same layer height (now known as “Constant Slice”) without compromising the look or quality.

How to Use Adaptive Slice

Adaptive Slice can be enabled in both Insight and GrabCAD Print.  Simply select ‘Adaptive’ as your Slice Style to see the results. The darker slices indicate a thicker layer slice, and the lighter slices indicate the layer slice you selected.

At AdvancedTek, we use Adaptive Slice to cut down print time on larger parts without sacrificing quality on gradually curved surfaces.  While this is currently an automated process, it’s the first step towards having full control over the layer thickness at each layer!
