3 3D-Software Magics
The Magics 3D software is a data processing program. The components here first need to be read in in 3D CAD format (file *.stl). After possible data record repair and construction of the support (component support construction), the layer data (slices) are generated for the LaserCUSING
process.
This slice data record which is generated (file *.cls, CONCEPT Laser slice file) can now be transferred to the ConceptLaser machine software (see Chapter 4 Part II ConceptLaser machine software).
X, Y and Z denote the spatial axes for the LaserCUSING
components in the Magics 3D
software and the ConceptLaser machine software. U, V and W denote the moving axes of the construction module. Please see the Magics 3D software manual for further details.
3.1 Reading the 3D data record into the Magics software
After opening the Magics 3D software and reading in the STL part, this is displayed on the screen. The position in the coordinates system is taken from the construction data.
Fig. 1: Magics standard screen
Version: 08 / 2011 8 / 29 www.concept-laser.de
With the command Move to default position, the component is placed against the coordinate axis in the positive range.
Fig. 2: Move part(s)
The component is then aligned in accordance with the coordinate axes. In addition, a flat surface is marked on the component with which it should stand on the construction plate command Bottom
surface/Top surface (see Figure 3).
Fig. 3: Base surface/Top surface
Version: 08 / 2011 9 / 29 www.concept-laser.de
With the aid of the Aline menu, the component is aligned on the axes. Then place the component against the coordinate system with Move (see Figure 4).
Fig. 4: Correct positioning of the component
At this point, you should save in the following way:
The STL part, here Pleuel.stl, should be cancelled in its original state and saved under the component name. The format used for saving can be *.stl or the more compact *.Magics.
Version: 08 / 2011 10 / 29 www.concept-laser.de
3.2 Correcting errors in the STL part
Typical errors in the STL part include:
Missing triangles
Inverted triangles or double triangles
Transverse triangles in the component
3.2.1 Missing triangles
Fig. 5: Missing triangle
3.2.2 Inverted / double triangles
Fig. 6: Inverted or double triangle
Version: 08 / 2011 11 / 29 www.concept-laser.de
3.2.3 Transverse triangles
Fig. 7: Transverse triangle
3.2.4 Component fixing information
Under Component fixing information certain errors can be displayed.
Fig. 8: Component fixing information menu
Version: 08 / 2011 12 / 29 www.concept-laser.de
The following values should be checked here:
Open edges
Open contours
Shells
Open edges or Open contours must display the value 0 after repair.
Shells means surfaces. For example, if the component is a solid ball, it has one surface. If the ball is hollow, it has two surfaces. In our training example, the connecting rod has one surface, not five (see Figure 8).
3.2.5 Component repair
Components are repaired using the repair assistant with the repair combination (see Magics 3D software manual).
If the repair is not successful, individual triangles can be inverted, deleted or the appropriate holes can be filled.
Version: 08 / 2011 13 / 29 www.concept-laser.de
3.3 Positioning for the construction process
It is essential that the following points are noted in order to position the component for the construction process:
Little support construction volume
No relatively long edges parallel to the blades
Allow blades to run up to the component over a corner
Run over narrow sides of the component
Provide support to release the component from the construction plate.
The figure shows the optimum position for the component.
Fig. 9: Position for constructing the support
In the example here, the component is rotated by 45 on the Y axis.
Important: First rotate in the Y direction, then rotate about the Z axis! Then return the component to the Standard position and move upwards by an
appropriate amount in the Z direction in order to be able subsequently to release the component from the construction plate (e.g. 0.5 mm for a wire-cutting machine).
Temporarily save at this point (Pleuel.stl)!
Version: 08 / 2011 14 / 29 www.concept-laser.de
3.4 Construction of the support without support generator
All surfaces at an angle of less than 45 to the construction plate must be supported!
Mark the surfaces.
Fig. 10: Marking the surface to be supported
Extend the surfaces down with the command Extrude
Fig. 11: Extrude menu
Then cut off the component at the height of the construction plate (first in the Sections view, then
with the Cut function) and remove the lower part.
Version: 08 / 2011 15 / 29 www.concept-laser.de
Fig. 12: Part construction of the support
The support construction now features a very thin web which in some circumstances may cause problems during production.
This web can be enlarged again by 10 mm with an Extrude command.
Fig. 13: Enlargement of narrow webs in support
After extrusion mark and delete the front side, cover surface and corresponding triangles of the side area, and use the Gen. triangle (Generate triangle) and Fill holes function to close the surface.
Fig. 14: Optimised support
Version: 08 / 2011 16 / 29 www.concept-laser.de
A support construction now needs to be introduced into the hole. Horizontal holes or cooling channels may be constructed with a diameter of up to 8 mm without internal support construction.
Therefore reduce the hole to 8 mm with a support construction and introduce a step of 0.1 mm in order to lift the original part up from the support:
Delete inner generated surface of the hole. Autofill holes for the two hole surfaces. Provide the resulting marked surfaces with an offset of -0.1 mm on the inside.
Fig. 15: Offset
Use the Standard geometry function to generate a cylinder with a diameter of 8 mm, the same length as the hole or slightly more (15 mm) and a tolerance of 0.01 mm. Use the Arrange function to position the cylinder in the middle of the previously closed hole. Remove the cylinder from the component with the Boolean function.
Fig. 16: Support for a hole greater than 8.0 mm in
Version: 08 / 2011 17 / 29 www.concept-laser.de
Important:
Save the component under the name Pleuel_Sup.stl not under Pleuel.stl!
There are two options here:
The component is fused to the support it is an STL part. Component and support can only be constructed with the same parameters.
If the support should be an autonomous STL part, the part Pleuel.stl (part positioned, but without support construction) must be called up and removed from the part Pleuel_Sup.stl with the Boolean function.
The original part may need to be provided in advance with an offset of approx. 0.02 mm in order to be able to carry out the Boolean operation smoothly.
Save the remaining support under Pleuel_Support.stl.

Version: 08 / 2011 18 / 29 www.concept-laser.de
3.4.1 Slice generation with the ConceptLaser slicer
The component can now be sliced into slices of typically 30 m with the predefined slice parameter sets.
Fig.18: Parameter menu of the ConceptLaser slicer with cusing standard parameters Slice thickness Layer thickness Beam compensation Distance between the island structure and the original contour Skin core Subdivision of the surfaces in the inner and outer area Additional contours Flush termination of the lasered contour with respect to the
component contour or allowance generation Islands Size of the exposure vectors.
(An island rotation of 45 avoids exposure vectors parallel to the coater blades)
Important:
The subdivision into inner and outer surfaces may not be applied with cooling channel parts as even powder application is then not guaranteed!

3.5 Generating the support with support generator
The following support settings create very fine support structures which can be removed very easy. Please note that this support can only be build up with a flexible coater blade. The coater speed has to be adapted for the flexible blade (should be 50% of the standard setting for a steel blade). All parameters have to be adapted to the part size and part form.
3.5.1 Choose manual or automatic support creation

Version: 08 / 2011 21 / 29 www.concept-laser.de
3.5.2 XY Offset
As smaller the parts are, as smaller the value can be. The maximum value should not be bigger than 0,3mm, the standard setting is 0.
Fig. 22: choose offset parameter
3.5.3 Hatching
The setting 2 mm in X and Y has the best results. The right rotation angle is 45 degrees.
Fig. 23: choose hatching parameter
Version: 08 / 2011 22 / 29 www.concept-laser.de
3.5.4 hatching teeth / borderline teeth
As bigger the teeth are, as smaller the connection to the part can be set. Following you see the standard settings.
Fig. 24: choose teeth parameter
3.5.5 Fragmentation
The adjustments for the fragmentation correspond to the hatching parameters. 2mm in X and Y create small crosses. The gap between of these crosses is the separation width factor 0,3mm. It is also possible to fragment the borderlines. If you combine both possibilities the separation width factor should be smaller than
Version: 08 / 2011 23 / 29 www.concept-laser.de
3.5.6 Perforation
The value for the beam varies between 0,7 and 0,9mm. This depends on the material. The height is the start height for the perforation. These settings can be changed in the machine library (see later point 8). The solid height is the distance between the perforation and the teeth to the part. Our experience shows that 1mm is a secure value.
Fig. 26: choose perforation parameter
3.5.7 Machine library
All these settings can be predefined and saved in the machine library.

3.6 Job preparation dental parts
3.6.1 Supports
Fig. 30: dental part with block support
A block support is used for the parts (see figure). The relevant parameters are:
Hatching (x,y): 1mm
Fragmentation (x,y): 0,5mm
XY_Offset: variegate between 0,1 and 0,8 according to the model/geometry (in doubt less or 0,1)
no borders
It is convenient to place a diminution at the top with the following parameters:
high 2mm
top length 0,4mm
fragmentation 1,0mm
Alternatively the pillars could be minimised, so that the connection could be minimised too (hatching 0,7mm).
Version: 08 / 2011 26 / 29 www.concept-laser.de
3.6.2 Slicen
Slicing in Magics the additional contour inward has to set up to 50m.

Fig. 31: slice parameters dental parts
3.6.3 Import the parts
Monomial bridges shall be built without islands. Therefore the option open without islands must be chosen (only software 9 old version). For multi-unit bridges it is advise to build with islands to minimise the deformation.

3.6.5 Heat treatment
In order to avoid stresses and deformations after taking the building plate it is mandatory to heat-treat multi-unit bridges/crowns. Parameters therefore are: Material treatment gas heating up holding cooling down
