Final model progress

Facade

Once again just try in 1:200 see what is going on and as result the print mad at me...Whole roof are in no support and show above.

Second try is using the support from the makerbot software, however it is weird that make everything become support...

So i just try back to basic and remove the roof and just print the walls only. The result still really good as shown. I started question is the printer print plate is not level? Meanwhile i help other classmate print their files with same printer everything go fine so i just back to sketch-up and check the file...



After a full investigation and find out the model is extremely not water tight and full of very small holes. Some face are not in positive face and inside the wall have internal face in it. (Credit to Isaac) The model start print correctly. However still a bit weird on the other side...




Try putting columns and see is the situation improved but it didn't...so i think is it the scale problem so i just jump to 1:100.


Unexpectedly, due to larger scale the wall have more structure to hold up each layers.







Columns really do the job and give support to the upper structure. And it is easy to remove compare to the support the software have.

Roof

Again the roof. I have re orientate the position to print due to 90 degree turn have less overhang. First test on the left is totally fail as i did not notice one side not even on the ground and it cannot print at the beginning. Second test at the middle using the support method from the software which helping me to know which point actually need the support. At last on the right just using my own little columns.

As in the facade, scale is a big issue. With my own columns support it print well.

Just note that the free standing column i had print this time is touching the limit. The highest column is 8cm and it start fail on its job to support the model during print. Even worst the raft of the column also fail too and ruin the model print. Long story short, columns may not always the method to solve this kind of problem.

Floor slab

In order to make the slab in sharp, large amount of blue foam at the middle need to cut away. However the cutting machine have its limit. Therefore i use drill to drill some bit off...


...and then sand to the shape i want by sand paper.


After fine sanding, is time to join two pieces together. I give more support to the join by adding stamp as attachments. UHU plus PVA are applied to give both short and long term bond.
