3d-scan to 3d-print

Post by karrob14 » Tue Jan 17, 2017 2:19 pm

I'm looking for a suitable way to print a laserscan point cloud on a 3d printer, which can affect the whole system (see photo), or even parts of it, or many parts that are combined to one piece, I am using a riegl vz-400i scanner, I have knowledge in auto-cad, 3ds-max, in bentley microstation and the add-on software terrasolid (terra-scan and terra-photo)
I know that this mesh must be waterproof so that the printer can interpret it properly and process it further
Does anyone know, how could it be print from the riegl-software riscan-pro to a finished 3d model?

Is it a massing model or would you need each componant as a seperate object

With that scanner (long range), it will not be very detailed and probably have a lot of shadowing issues.

I guess it depends on your use-case, why do you need it printed?

yes , you are right, the object is massive, but i need it in parts and also as the whole thing, but printing ist a request by a department in our house to have a table-model for exhibitions and verifications

i have the possibility with this scanner to scan details in very high-resolution and as a table model in a smaller scale to print, as requested by the department, to exhibit it and to prepare for presentations

Occasionally I'm 3D printing small excerpts from point clouds for demonstration/visualizations purposes. I'm working with heritage objects like buildings, underground spaces and excavation sites. The process from point cloud to 3d print can be, however, like others already motioned, a rather laborious process with a lot of difficulties, especially if you are aiming for high detail or working on filling up occlusions and making the model watertight.

I like to use programs like cloudcompare or meshlab to apply the Poisson Surface Reconstruction filter in order to create a mesh. Most of the times the created model needs to be 'cleaned' in modeling software like 3D max in order to remove unwanted artefacts. I know that there are also several commercial software packages available that are offering these kinds of functionalities.

I've added an example of a 3d printed underground fortress-hallway.
