First tests of architectural prints

[viralata 78]

Hello,

I'm an architect, passionnate about Blender, so it didn't took me long to fall into 3D printing :-P

Here are the first tests I did after printing downloaded model to test, the pictures are not so great, and the layers are not so visible in reality:

First test for overhangs:

A print of an old blender model, and the render of the same model. I printed it in 2 sizes the big one took 8 hours, the small 7 minutes in fast low quality. Once again, I wanted to test the overhangs ability, and I was impressed:

And then a test for a workshop I may attend (I will organize workshops about the use of 3D printing for architects later anyway), to see how fast a small nice model can be printed for the people to take their model home. 10 minutes in low quality, 20 in normal, 25 mm long. No support needed :eek:

Nice work. I've just started experimenting now with the new 'LAYBRICK' filament that is basically printable stone. I've had good results with it, though not yet quite what they advertise. I'm still impressed with my results and I think it would be great stuff for architectural prints.

Cheers,

Troy.

love the "desert structures" .. we get a lot of student-architects in and would love to show off your models to them (printed in laybrick / sandstone filament).

Would you care to share some of your work(files) with the community so people can see what is possible and to spark their imagination ?

demo3dmodels @ fablab013.nl

grtz,

Pete

I would be happy to share my work under a Creative Common licence, I just have to take the time to choose the models that work.

You can check my site there to see some of the things I would like to print, if I manage it :smile:

some example of my design classes with Blender

some videos I did

By the way, I have to test this laybrick filament.

I'm launching a fablab around my countryside (www.chantierlibre.org), just the beginning of it, we have a shapeoko cnc router too, so be sure I will keep in touch.

Here are some other tests. I still use some old models, as I have no time to design new ones for printing those days.

A raw earth house, from a very old image I did in Blender, printed very well. I just changed the roof as it was too flat:

The following one was more tricky, it is an exemple of quick sketch design with the subsurf modifier I did for my book about Blender:

It needed a lot of support, and as I forgot to add a raft, the two small feet went away during the printing. The bottom, with all the supports needed a lot of sanding, and the othe parts just small sanding:

Once sanded:

And here is the inside of the small round house, to show that I had no trouble even without support.

I uploaded the stl files on the lab site:

Simple house test

Earth House n°2

Earth House n°1

New ones are coming...

There is cool stuff here. Remembers me on the first Star Wars movie in some ways.

very nice stuff ! did you have to clean up your blender files at all for printing or did they all come out so good ?? really love the print results..

Ian :-)

 

[viralata 78]

It depends of the models: The first earth houses had no wall thickness, so I had to use a solidify modifier, which is very quick.

The other ones where printed just like that, but the strange subsurf house lost its feet on the way because they where too tiny, so I will have to change it. And the bottom of it, wit all the supports was very ugly before sanding.

Here is my last model:

I used the softbodies of blender to generate the shape, with a solidify modifier to give it thickness. It's inspired by Gaudi and the way he designed the Sagrada Familia in Barcelone:

i am absolutyl loving this.... :-) :-) :-)

 

[viralata 78]

Thanks Ian.

Here is a low poly version:

I have a lot of "wires" and blob as you can see on the next photo, but only on the pilars. I tried to lower the speed to less than 40, and lower the temp to 210°C, but it did'nt improve. Any thoughts ?

It is retraction problem, so you should switch to full settings and set retraction 4.5.

 

[viralata 78]

Thanks for the advice, I will try a new print one of these days.

Here is a timelapse of the whole process, from designing in Blender to printing. Hope you enjoy it and that it's not too long:

Cool staff, thx for video! Merci!

 

[viralata 78]

I posted on my website a post containing at the end the .blend files and the two stl files:

They are under creative commons CC-BY-SA, feel free to use them.

Cool video, blender evolved a lot since last time I used it, like 10 year ago

Here are my last test with dual extrusion: 3.5 cm long, printed in white PLA and natural PLA, at 50mm/s, 0.6mm layer, with ooze shield and wipe/prime tower.

Played a bit with light (and a laser) :-P

 

[viralata 78]

Here is the last test with dual extrusion. In spite of the wipe and prime tower breaking down (it's not included in the raft in Cura 13.11.2) and therefore a lot of oozing, and some underextrusion of the transparent PLA, I'm quite happy with the result:

Stunning what you are doing with this. I just love it. Please put a link to this thread over in the "latest print" topic. Maybe include just a single picture from above.

 

[viralata 78]

Thanks Gr5.

Some technical details:

printed at 0.1mm height, 20mm/s, 195°C, with ooze shield and wipe and prime tower.

The tower was not firmly enough stucked and broke down. Even with the ooze shield, it's much better to stay aside and remove manualy some of the oozing to be sure. As the printing lasted 38 hours, some parts were left like that and and some white want into the transparent.

I have some holes betwen the two materials in the "voronoi" wall, not sure if it's only because the transparent is underextruder a bit.

this is becoming one of my favorite treads on the forum... woww !!

Ian :-)

Whow, these are awesome.

You did not add any license with some of the files, are they free to print and show around as examples?

And if you want to increase exposure, you could put them on youmagine.com

 

[viralata 78]

Thanks for the nice comments.

@ Daid, all of my work (except some very rare cases) is under CC-by-sa, so feel free to use it, just crediting me in a sort of way.

I know I should put them on youmagine, it's just that most of them have some things I would like to improve before publishing it (for example the last model would be much better printed in several parts but I wanted to try it in one print), and as I have no time to do it, they stay useless on my computer :oops:. Maybe during the hollidays...

oh my lord these are beautiful and may i just quote "i change the roof as it was too flat" looks like we got someone who actually gets 3D printing
