Laser Additive Manufacturing

Posted on

DMC software is a great tool to prepare and control laser additive manufacturing / 3D printing processes like Selective Laser Sintering SLS, stereolithography and others.

Import multiple STL models for single laser additive manufacturing process

Multiple STL files can be imported or the same file can be multiplied. Use 3D Printing command to combine all the objects and process them together layer by layer.

All the processes and actions that needs to be done before or after printing of a layer are described once in separate recipes.

Different objects can be printed using same or different parameters.

STL file sliced for 3D printing

STL file with 2 million triangles sliced by 10 µm.

Fast slicing of large objects

Using 64-bit technology DMC handles large and complex objects most other programs just don’t. Import large STL files with millions of triangles and slice them with high resolution.

Slicing 100 MB STL file with ~2 million triangles with 10 μm slices takes only seconds. And since DMC controls all the hardware directly, this time already includes all preparation of all motion commands.

No need to wait for hours to get the complex model prepared for laser additive manufacturing.

Repair faulty STL models

Sometimes STL models comes faulty. With some planes missing, or some extra ones, or with gaps and planes not joined.

Those errors prevent filling volume of the slice and may damage the printed object.

DMC slices STL model and then displays potential errors. Each slice can be repaired automatically or manually, giving user full control of how the contour should look like. Repaired files are fully ready to use for laser additive manufacturing.

Contour Hatching For 3D Printing

STL model sliced and hatched with contour hatch.

Fill volume of the object with hatching

To successfully use STL model for additive manufacturing, its volume must be filled.

To fill the volume of the object, user can select several types of hatching: line, cross-hatching or contour.

For each hatching type a beam spot compensation offset may be added.

Several types of hatching for each layer is possible.

Supports for Additive Manufacturing

Supports for Additive Manufacturing

Automatic support generation for 3D models

Some additive manufacturing processes requires supports for the models. Either to make sure overhanging parts are made correctly or to support object for postprocessing.

DMC generates supports based on model surface angle. Both bottom of the model or internal parts can be supported. To make sure support structures are easily removed, process parameters like hatching distance, laser power and scanning speed can selected separately for supports and their tips (parts touching or close to the model).

Additive Manufacturing Process Control

Control laser additive manufacturing process of 3D laser printing with DMC.

Control the whole process

DMC laser machining software controls machine hardware directly.

Control galvo scanners, positioning stages and laser source.

Use I/O and serial port to control devices on the machine.

Create recipes for process initialization and actions before and after each layer.

Print whole object or just the part of it.
