Is it a model of a particular castle?

II don’t think so. I found the model here: I’m looking other things that would be fun to see in miniature if you know of any.

It looks a bit weird, the main house has large windows (so seventeenth or so century, post- defensive function) but the curtain wall is definitely a pre-cannon, 14th century or earlier style. Anachronistic 3D modeling! Also it’s fairly generic and symmetrical, that usually only happens when these things are first built and not after a few centuries of expansion, rebuilding, etc.

Sorry, I don’t really have any suggestions for other objects to print.

(My dad was professor of ‘Material Culture in the Middle Ages, with a focus on castles’ for 25 years. I tend to Notice castles.)

Which slicer were you using? Slic3r or SFACT?

On this particular print I was using Slic3r. I use KISSlicer sometimes depending on the model. For example, When I was printing the tree frog model from, Slic3r kept mangling the frog’s feet, but KISSlicer did a great job. I’ve never used Skeinforge or SFACT. Do you recommend SFACT?

SFACT is skeinforge, it’s the engine used behind the Cura software on the ultimaker.

Cool. You may like this thing I’ve been working on…

In particular, castle.c which produces a rather elaborate procedurally generated castle model, or rather, it produces an openscad program which produces such a model. Still a bit of a work in progress though. And it is a bit of a CPU crusher, takes something like ~15-20 mins to render a castle on dual core 1.8GHz i7 – no idea how long to slice, but I am aiming for the models it produces to be 3d printable (no ridiculous overhangs, etc. – luckily the constraints of stone and mortar construction are not so different from those of 3d printing wrt overhangs and so on) but I have not tried printing one yet.

Edit: uploaded an instance of this program’s output to thingiverse:

Very cool castle! I noticed the one on thingiverse is more elaborate than the one rendered by the code generated by the github project. I’m assuming there are some configurable options somewhere, but I didn’t see any in the castle.c file. @Stephen_Cameron

It’s random, or rather, stochastic. Each time you run it it produces a different model. Sometimes it makes something really simple and dumb, sometimes it goes nuts.
If you want repeatability, you can replace the line in castle.c that says “srand(tv.tv_usec);” to “srand(1234);”
basically, set the random seed to a constant, and it will always produce the same model. Put in different constants to get different models.

Será que as traduções do Google Translate faz sentido? Se não o fizerem, talvez possamos reformular algo para você.

@Stephen_Cameron Here are some photos of your castle model printed small with my “trick nozzle”.
