Transcript of 3D Printing
noobs create 3d files
slice it, layer by layer
different printers, different settings
filling and size of the layers
resolution and toolset
heat and extrusion
speed and movement
Home 3D Printer:
FDM = Fused Deposition Modeling (PLA,ABS, Nylon ...)
SLA = Stereolithography (photopolymer)
DLP =Digital-Light Processing (photopolymer)
Industrial 3D Printer:
Granule based: SLS = Selective Laser Sintering or Melting
Powder based: PP inkjet-head deposits plaster (Z-Printer)
PP is the only one with full colour support, but needs to be infiltrated
Even if it looks good rendered
does not mean it prints well...
Get it towards the printer:
.STL --> GCode
different printer technologies
Rough surface, no color, breakable
Finish it up
loose support structure
PP color parts need to be infiltrated to not break
SLS is white, for single color also infiltration
file format, size (scale), rendering, polygon count (detail) , manifold, holes, flying polygons ...
3D printing for designers can be hard.
Create, optimize, clean and convert 3D Model
Choose 3D printing method and the right printer settings. Attend print and re-print....
Software and settings overkill.
3D modeling software is hard to learn and complex.
All printers are diffrent!
Try and error.
Hard to polish,
hard to sand,
hard to infiltrate,
Create 3D Model
Choose the fitting software
CAD 3D Scanner
All the CAD ones and Sketchup
Sculptris & ZBrush
Rendering: Unlike 2D printing there is no good
preview (Acrobat Reader / PDF)
What you see is not what you get!
looks all diffrent
polygons & faces
light & shadow
normals and orientation
Each software has its own scale
JAN NORTHOFF & SAMUEL CARLISLE
Webdesign and Development
3D Copy Shop:
Scanning + Modeling + Printing
3D Printing and Community
Sell new 3D printers
Repair 3D printers
Talks & events
123 Autodesk catch
Each Software brings own format.
Always export to .STL
expensive and hard to handle
good for final prototype
bigger print sizes
besides plastic materials, also rubber like, ceramic, metal ...
More and cheaper photopolymer printer: SLA (Stereolithography).
Static improvement of Open Source 3D Printer Projects. Self reproducing machines (RepRap).
Better workflow, better software:
Pronterface and Rapetier.
Stable construction, different and new materials.
Industrial revolution will take place on the long run...
Use Meshlab or cloud.netfabb.com
For 3D Home Printers: Repetier
(slic3r and skeinforge)
Use Meshlab to check
function or visual prototype
inside is outside
points not connected (manifold)
too much and too fine details (min: 1mm ALL parts)
too big (average size is 50mm x 50mm x 50mm)
software bugs and issues
Industrial 3D Printers
relatively cheap to buy
low material costs
need maintenance and repairs
calibration and settings
hard to handle
good for testing and useful parts
small print sizes (200mm 200mm 200mm)
low resolution (FDM)
not able to print all shapes (overlapping)
multi head printers for support structure
PLA, ABS, Nylon , new materials like wood ...
