Rotary 3D Print



Compared to a Cartesian process, rotary printing uses far less support material and prints faster.


Stresses are directed inward toward axis center. No warping, no bed-peeling.


This is unlike any other additive process. For certain applications, this capability is critical.

Rotary 3D Print
Process (more details in manual):


Generate CAD file of the final part

  • Must be the same ID as the print bed/mandrel (can be any diameter, but must match)

  • Fully compatible with multi-material printing

  • Compatible with hybrid operations, with additional steps


Use the Diabase Wizard to assist toolpath generation

  • Automatically "unwrap" CAD file

  • Slice normally in Simplify3D

  • Automatically re-map onto correct machine axes


Configure machine for rotary operations

  • Install rotary axis and optional tailstock (30 seconds install)

  • Install round stock in ER32 collet or rotary vise

  • Run macro to configure A-axis for printing and auto bed levelling

  • Home axis and level bed/mandrel


Print then remove part from mandrel

  • TPU can be released directly from mandrel with solvent and a long prying tool

  • Rigid material will require a sacrificial layer - either a layer on the mandrel, or a layer of printed support material (preferably soluble)

Similar build, permanent to mandrel:
