The walls of the second floor are made the same way as the first, 3mm birchwood plywood with 1/32 thick Monster Modeling brick. I designed the second floor windows to be made with the laser cutter and have the mullins on both sides with the glass in the middle.If anything it was easier to make the windows from basswood then using the resin printer. The glue holds better to the wood. The column design was carried through like on the first floor and it appears the nesting I was looking for will work just fine. Here in photos is the process and progress. You will notice the column colors are changing. I did not like the first color and I still not sure if I like this new version, definitely will need to be toned down some.



Laser set up to cut out walls.



Laser having just cut out walls from Monster Modeling American Aged Brick Sheet



3mm birchwood plywood and brick sheet ready to be glued together.



Parts glued together using 3M 468 double sided tape.



Wood frames cut out and ready to be made windows for front wall. Brick has been 'painted' using rust-red dry pigment and sand grout (scenic glue and wet water) used to fill in mordor lines.



Windows in and walls glued to floor.



Second floor together with most columns in place. End columns need to be painted before attaching to wall. That is progress for tonight hope you like it so far.

The second and third floors are where the actual dress design, fabric cutting and sewing will happen so they will be much plainer then what is seen on the first floor. It is much like the old joke of the devil convincing a guy that hell isn't so bad, showing him golf courses, beautiful woman, white beaches and so on, when he he chooses hell over heaven he finds himself in hades as it really is, when he says it it not what he was shown the devil says, 'oh that was the marketing department, this is operations'.

I started with the floor that will also be the ceiling for the first floor. Using the Lightburn program I designed various length floor boards, added cracks, marbling and even nail holes to create a pattern the laser could emboss into the 3 mill basswood and then cut out the needed shape. Here is how the design looks in the program:


It looks rather like a mess but if you blow up the photo you can see the individual boards. The various colors tell the laser how fast to cut, what power setting to use for that color and how many passes to make. You can see the rates and color chart on the upper right side, everything is in seconds and metric. There are six separate board designs placed randomly and then cut and pasted to duplicate the design.

The ceiling side has a picture design I found of a European church ceiling and printed it on 12 x 12 cardstock using the Cameo print/cutter and a Cannon printer.For the parts of the ceiling that are the back warehouse and front walkway I used a photo copy of the wood cut design used for the floor



And here is how it turned out. Not Monster Modeling but good enough for what I am doing:

With the first floor essentially done I moved to the second floor. Each floor is designed to nest into the floor below. I am using the concrete/limestone columns and facing designs to act as the retainers for the floor above them, holding each in place. This also allows the various glue seams to be hidden from view. As I mentioned I am pushing Tinkercad pretty much to it part size limits on this project so am unable to produce a true finished CAD design in one frame, however I have been able to get more parts in one drawing then I initially thought possible. So here is a close approximation of what I am shooting for.

So I promised to show how the doors were made and said I'd post it about a month ago ::)  ::) Oh boy, well better late then never. I designed the main entrance doors using Tinkercad and came up with this design:



The 3D resin printer made two copies. I designed the doors so the glass could be slid down into the middle for the top window and I had back frames made to hold the other two door windows in place. Once printed I painted them red with a rattle can which produced a textured finish. Not sure I like it but I went with it anyhow, from a distance it doesn't show up much. I cut the clover glass to shape, used canopy glue to hold the glass and added the door handles that had been 3D printed separately and painted bronze. So the following pictures will show the steps and the result.













And that's how I made the doors. The single doors were made in the same manner.

I see our guru of Forum software has added a new category for new tech tools, thanks Rusty! And thanks to everyone who has stopped by to see progress. I have been a little slow on this project but will catch up the thread today.

Quote from: R Edington on December 21, 2023, 10:37:46 AMHey Tom,

 Great work so far and thanks for sharing your work with drawings.
It's great that technology is getting so affordable for the hobbyist. 

What software do you draw with for your laser???
Are you using lightburn to run it???

I built a 100 watt CO2 laser with a 18"X36" bed, have 4 resin and 3 FDM printers, and a Cameo Pro that I use for complete builds in N scale,


 Thanks
Rodney;

Thank you for stopping by. To answer your questions I do most of my drawing using TinkerCad, even if I am going to export the file 2D for the laser or the Cameo cutter. I sometimes use the Silhouette Design program, especially if I am going to print a design and have the Cameo 3 cut it out. Once the design is finalized I make an .SVG file and send it to Light-burn to tweak the design for shading, engraving and slight design changes if needed. Then the Light-burn program runs the laser using an old Mac Laptop I have. My laser is no where near the power you have made. Mine is a 10 watt diode laser made by Sulpfun. Your 100 watt CO2 is a serious machine. I just had my Elegoo Saturn 2 fry the mother board so I am using the little Elegoo Mars 2 machine I still have. Not sure what happened to the Saturn but I managed to fry the innards so not sure if I will rebuild or get another at some point. The little Mars 2 gets most of what I need done so all OK for now. Thanks for following along and hope I answered your questions.

Good Morning Everyone;

The weekend is here, my wife had to tell me since it feels the same as the work week these day (and that is a good thing!). I like the tilted chimney, at least they put tie down wires on it to keep it tilted. Tomorrow we have Deb's sister and husband visiting for a week so I'm on clean the house duty. I am getting more parts made using the 3D printer but that is about it for modeling today. Yesterday was interesting in the stock market, Meta, the parent company of facebook released earnings and their stock went up 20%! I own Meta so yesterday was a very, very good day.  ;D Hope everyone has a great day today as well.

Good Morning Everyone;

It is good to see more and more of the gang checking in. I need to get with Dan and see if we can get a modeling challenge going again. I am working on seeing if we can get a kit prize this year for the 'Grand Champion', nothing too crazy perhaps a gold bar, bitcoin or more likely a small, very small craftsman kit! Anyhow, anyone have any thoughts on subject, I know it has been mentioned before? My thoughts were perhaps a 5 x 6 max size diorama scene focusing on railroad theme, Thoughts?

Hope everyone has a great day.

Welcome back to the clubhouse Slim, good to have you back.

Today I was able to get some 3D design and printing done. Tomorrow we will see if I got it right. Hope everyone had a great day.JIM

Modeling Wizardry / Re: Considering 3d printing
January 30, 2024, 10:00:11 PM
A new category 3D printing, I love it! First, 3D printing can be a hobby all to itself. I got into it to help improve my structure modeling such as unique windows and such, so I have learned as much as needed to accomplish this. However it can do far more if you invest the time and money. Second, there are two main methods of 3D printing, filament, where the resin comes on a roll, is fed into a nozzle, heated and placed on a platform. It can produce fairly large, complex items fairly quickly. The other is using a liquid resin in a vat having a clear bottom. A diode screen under the plate produces UV light in a pattern which hardens the layer formed between it and a vertical moving platen. It produces very fine detailed parts but is slower. That is what I use so my recommendations will be for that type of printing.

I started with the Anycubic 4K entry machine. Cost is about $150 from Amazon. It is a great machine to start with. Another similar quality machine is made by Elegoo, actually the Elegoo is a little better quality. There are rapid advancements happening with all 3D printers. I currently have on order my next machine that will be 14.4K. Higher K, higher resolution.

For resin I have settled on the Anycubic tough resin, cost is $27 a litre from Amazon but I wait for sales and stock up, usually at $20 a bottle.

You also need a UV dryer, they go for about a $100. The parts are only about 75 percent cured from printer and the dryer completely hardens the parts. Finally wear nitrile gloves so you don't get an allergy from the liquid resin.

As for programs I use Chitubox to make the design file useable to the printer. I use Tinkercad, which is free, for designing my parts. Took me about two weeks to understood the basics of it but it gets easy as time goes by. Also, and most importantly you don't need to design parts to print parts. There are many sites like Thngverse and Cults that have free or inexpensive files you can down load and go straight to the printer.

There are a ton of YouTube videos available, check the 'how to start' ones and you will quickly see what it can do for you.  Hope that helps.

Good Morning Folks;

Looks like I start today. Things starting good, had a full night of sleep, something I no longer take for granted. We are visiting friends today, perhaps a Hobby Lobby in my future and then perhaps some fun at the layout. Cilly but sunny so I am all set. Have a good day folks.

GoodMorning;

Well there is no joy in motor city today. I could not believe their coach went for 1st down on forth being up 14 and having one of the best kickers in the league. I am just a couch coach but even I could tell that one play cost them the game. In blackjack it would be the same as hitting when holding 19. Oh well.

I did get some work done on the clothing factory. Thought I would share a picture of what the third floor front will look like. All laser cut or 3D printed.The Bay windows are just set in place so a little crocked.

Have a great day folks.
