3D output file for printing
Hello, I was wondering if someone already tried to print some caves in 3D, using a 3D printer. Any input about how to get a .STL .OBJ .AMF or .3MF (which I know are 3D format for printer). If someone did a printing, any issue / success to share ? Like I guess any small narrow passage will be hard to print if the final print put some kind of pressure on it. Everything will depend of the scale obviously. Anyway, maybe it’s just a dream but I thought it’ll be possible to do such a thing those days : ) Have a good evening everybody, Franck Tuot
I used a mesh program to convert the therion 3d output to the .obj format. Worked to view in 3d with a Google cardboard viewer. On Jan 30, 2018 9:39 PM, "franck TUOT via Therion" <therion@speleo.sk> wrote:

Hi Franck, I exported a .dxf file, and the guy used it to convert it for printing. If you can get a two tone color printing that would be the best since the printer has to print a support for the cave parts that are not at the lowest altitude (usually most of it and the support is larger than the cave). The best would be to use a material that will be removed (there is something that can be dissolved I think), so you would keep only the 3D print of the cave. Phil

Therion’s Loch viewer is able to export VTK file, which is compatible with several 3D modeling programs and you may convert it to format for 3D printing. Martin s.

Another option would be to engrave it into a glass block using laser. Has someone already done this? Am 2018-01-31 9:20, schrieb Martin Sluka via Therion:

3D Output Suggest you use the open source Meshlab program for editing, converting between 3D formats and point clouds. I have done 3D crystal engraving using a sub-sampled point cloud. This is particularly effective when lit by variable LED's but you will be limited by the available crystal sizes. The laser creates micro-cracks in the crystal at each data point. You have to experiment with the density of point cloud, scale and offset it to fit inside your chosen crystal block size using (0,0,0) for one corner or as per your engraver's requirements. For 3D plastic output, find someone familiar with it who has a machine and work with them. The main problems are small passages and having to use lots of cutaway supports. You can subset the model based upon elevation and then 3D print each elevation range using a different colour plastic - helps with model visualisation and display. You can try fused powder deposition but this will give a solid form and small passages will be fragile. If you want realistic colour from 3D photogrammetry models then this is possible by subsetting the 3D model and printing out small sections with no overhangs plus added joints to aid assembly but the results are very time consuming and not the best. Might be useful for a cutaway passage/chamber display. Kevin Dixon On Wed, Jan 31, 2018 at 9:53 AM, Benedikt Hallinger via Therion < therion@speleo.sk> wrote:

Yes, we've done that in 2012 for Fuchslabyrinth maze cave, based on 3D output from Therion. The laser company (www.3D-Cubeworld.com) had to post-process the data into "their" format. Another company also offered such service: www.3d-lasershop.de (they need STL or OBJ data) And Dr. Jeannin (www.isska.ch) also has access to such service.
