Changes & Additions
AddedWireframe Output options for Brace Toolpaths. Creates line segments and partial chains along the inside edge of existing passes within an operation. The resulting geometry can be used to create more accurate entities for brace toolpaths. See documentation for additional information.
AddedStart Point Output for all operation types. Creates 3D points at the end of each open toolpath during generation. The resulting points can be used to create Start Point Indicators or other geometry. See documentation for additional information.
ModifiedError handling by replacing ambiguous "Draft to Plane" messages encountered in the previous version. Updated error messages should be similar to earlier versions of Print3D.
ImprovedToolpath start position controls for all operation types. New "Toolpath Start (Open)" and "Toolpath Start (Closed)" group boxes now contain parameters for Start Point Indicators and Seam Guides, respectively.
ImprovedPart Model Viewer functionality, including updates to the Layers List Control to support standard Shift, Ctrl, and arrow key behavior.
ImprovedPart Model Properties dialog by replacing optional "Model Output" checkboxes with simplified "Output As" radio buttons that more clearly present all available output options.
FixedPart Model output to ensure all levels and geometry displayed in the Part Model Viewer are removed from the Mastercam Levels Manager on exit, cancel, or when Save is not selected.
FixedExclusion Volume implementation for Simple Brace Toolpaths. Resolves errors that may occur when generating Double Connected Braces and similar toolpaths.
FixedAlternating Connected Passes implementation in AM Surface Outline operations. Resolves errors that may occur during toolpath generation.
FixedSeam Guide geometry to reference the Print Plane WCS origin. Changes to the WCS origin should no longer affect existing seam guides or seam positions.
FixedPart Model creation to resolve multiple issues introduced with Mastercam 2026 R2.
FixedOther minor miscellaneous bugs.
RemovedStock Model creation and the associated Save dialog previously displayed after Part Model Properties. Depending on the selected output option, the model is now automatically saved after creation or opened in the Part Model Viewer.
Modified
Software components and associated files updated for compatibility with Mastercam 2026.
Modified
Software components updated for compatibility with updated Mastercam licensing and an updated version of the LSAM Print3D network license manager.

AddedAbility to suppress the output of boundary passes generated by AM Slice. Suppress boundary output check box added to Parameters → Boundary → Passes.
AddedAbility to specify a Working Coordinate System (WCS) and associated build plane for all operations, using the General → Planes property page.
AddedBrace toolpaths for AM Slice operations, including a new Parameters → Brace tab with Passes, Lead In/Out, Process, and Bead Geometry pages; plus Exclusion Volumes and Corner Radius options exclusive to brace passes. See documentation for a full list of brace features.
ModifiedCheck Volumes have been renamed to Exclusion Volumes in AM Slice.
ImprovedMelt reduction amount for overlapping beads is now calculated with Overlap Push Adjustment, found on the Parameters → General → Process page.
AddedIndependent lead-in and lead-out settings for open vs. closed AM Slice boundary passes and AM Surface Outline toolpaths.
AddedAbility to choose between closing open passes or allowing them to remain open when applying check volumes to boundary passes.
AddedBackplot tool holder now resembles the LSAM nozzle.
ImprovedTrim to check volumes checkbox moved to the geometry page; Close open passes checkbox added alongside it.
ImprovedSeam guide starting point and seam avoidance offset now remain more consistent on toolpaths that change direction due to check volumes or geometry changes.
ImprovedPosted NC files now use a leading % character on specific comment lines, preventing runtime errors caused by nested parentheses in file or toolpath names.
FixedExtra top layer duplication when multiple bodies are selected in a single toolpath.
FixedRaft layers not being cut by check volumes.
FixedRaft layers for spiral toolpaths not obeying the non-suppression of tangential following on bridge moves when linear inches are below 15".
FixedMelt reduction anomalies with infill and outline toolpaths when applied on less than the 3rd bead option.
FixedRaft layers not obeying Change in Angle per Layer on infill passes.
FixedRare scenarios causing print models to have a small section created out of plane.

Files saved in 2024 cannot be opened in the 2023 version.
AddedStart Slices Relative to Origin feature — prevents toolpaths from starting at a height other than the defined layer height. On by default for all new toolpaths.
AddedCorner Pull Back support for spiral toolpaths.
AddedMore control over which pass Melt Reduction occurs upon.
AddedAutomatic prevention of out-of-machine-bounds lead-outs for VLP and ALP toolpaths.
AddedAbility to apply a seam guide leader seek limit (default seek remains infinite).
AddedAbility to apply start point indicators to AM Slice toolpaths turned into open paths by check volumes.
ImprovedThin wall now supports ramp up and double lead-outs.
ImprovedSeam guides now only affect toolpath loops physically crossed by the seam guide leader geometry.
FixedSparse fill incorrectly applying melt reduction on non-bridge moves.
FixedAM Outline and AM Surface Outline toolpaths keeping bridge move melt reduction active beyond the bridge when corner pull-back occurs near the bridge move.
FixedSeam guide leader geometry seeking from the back rather than the tip of the line based on the selection direction.
