NEAR NET SHAPE PROCESS

Benefits:

Save Time

Print FASTER - surface finish doesn't matter, so print with a bigger nozzle and taller layer height

Save Money

Only use the material you need. Don't start with expensive stock material.

Strength

Print hotter, with higher extrusion. Fill in all the gaps and get great layer-to-layer adhesion.

Accuracy

This is a CNC-finished part. Additive accuracy doesn't even compare.

Process (more details in manual):

1.

Generate larger CAD model than your final part

  • Option: use slicer to scale up the final part

  • Offset final part by ~1mm in all directions to be milled

  • Raise part above bed if tool should mill entire vertical wall

2.

Slice print file with Simplify3D

  • Use high heat and extrusion to improve layer adhesion

  • Maximize layer height and speed to minimize print time

  • Increase wall and ceiling layers to ensure solid infill in final part

3.

Generate subtractive toolpaths with Fusion360 or HSMWorks

  • Use CAD file from step 1 as stock (including any Z-offset)

  • Generate toolpaths with normal CAM cycles

4.

Run process files on H-Series CNC Machine

  • Either individually, or combined with Diabase Wizard

  • No additional machine setup is required! 

    • Stock location is known from the print process; the same machine coordinates are used for CNC operation.​
