I can create stl files for rapid prototyping from solid models in Autocad, but I would like the option of creating stl files from surface models in Autocad.

I have been told that my best bet is to switch to Rhino (another CAD application) because Autocad just can’t do it. Is that true?

Can Autocad export surface models to any other format than stl that I might be able to use in my Roland Modela4 software, such as .3ds?

That’s the only way I’ve been able to do it.

This video is done at Center for prototyping and testing of industrial products, Osmaina University, Hyderabad, India. Selective laser sintering is an additive layer manufactruing technique and is more familiar as one of the Rapid Prototyping Technologies. The process follows a layer by layer building. This is video made using FORMIGA P100 of EOS Gmbh, Germany

Rapid Prototyping provides assistance to speed the development of new components. As soon as such components have been designed on a CAD system, computer-guided machines can use laser sintering or 3D printing technology to create scale models from resin, plastic powder, acrylic, wax or metal.

The technology

Starting from a 3D image, a part is built slice by slice from bottom to top, in a vessel of liquid polymer that hardens when struck by a laser beam.
Schematic overview of the stereolithography process

Starting from your STL file, the required supports for overhangs and cavities are automatically generated in the model under construction. The support and model files are then “cut” into thin horizontal slices and programmed into the stereolithography machine.

This machine then uses a computer controlled laser to draw the bottom cross section onto the surface of a liquid polymer that hardens where struck by the laser. The part is then lowered to a depth corresponding to the section’s thickness and the next cross section is then drawn directly on top of the previous one. This is repeated until the part is finished.

Stratasys FDM Process
Step 1: Pre-Process
From 3D CAD data, pre-processing software automatically slices, calculates support structures, and creates toolpaths that are optimized for the system.

Step 2: Produce Part
Parts are built layer by layer in an additive process. Extrusion heads lay down thermoplastic build and support material to create each layer.

Step 3: Remove Supports
Temporary support structures are easily removed. Soluble support material automatically dissolves in a water-based solution. Break-away supports simply snap off by hand.

TransMagic STL PRO is a 3D CAD data repair and exchange software application designed specifically for medical, digital manufacturing, rapid prototyping (RP) and 3D printing industries. Anyone needing to use STL (stereolithography) files can:
- VIEW a wide variety of native and neutral 3D files without CAD software or licenses.
- REPAIR geometric errors to create water-tight solid models.
- TRANSLATE models to accurate STL files for rapid prototyping, tooling and manufacturing.

It’s easier to repair a CAD model than an STL file!
