Outstanding work. Thank you for showing this.

The above is a model of a manor house with no known prototype. Note the balusters and the segmented dormers. The STL files can be downloaded at charles.dollins.org/buildings/

I do not know how to remove one of the duplicate posts.

These are photos of British style terrace houses of the early 1900s. The same building in stone. The STL files for these buildings can be downloaded free at charles.dollins.org/buildings/

I will add a stone terrace house to my web site. It is exactly like the brick terrace house but in stone.

The half timber was about half 123Design and Inventor Pro both from Autodesk. All the rest are done using Inventor Pro. All of my prints are thin (1 mm) so warping can be a problem. ABS warps and PLA does not. They both glue well with MEK. Printing a 45 degree bevel on the bottom of ABS produces warping. Much less so with PLA. PLA is impossible to cut with a knife so I use a Dremel.

Please go to the url charles.dollins.org/buildings/ You can download the STL files for all of the buildings. There are no instructions but I posted photos of all sides of the building so the various pieces should be identifiable. If anyone has a building that they want the STL files for and it looks interesting to me I might be willing to produce the STL files for it Another slight problem is the joints at the corners of the buildings. Some of them require the sanding or filing a 45 degree edge. This is not difficult in ABS but is in PLA because of the increased hardness of PLS it is difficult. Since I now only print in PLA I am now incorporating the correct angle for the joints.

I am not sure but I think I tried to attach an STL file and could not do it. As we have just seen it is difficult to keep malware out. One way to do that is to keep exe files out. There may be other file types that can cause difficulty. I just don't know. The "they" above is whoever wrote the code for this site. I don't know them and I do not know how to write that code.

All of these designs were done with Autodesk Inventor Pro. No other drafting programs. The texture is a big problem. You can download the STL files from charles.dollins.org/buildings/ and look at them in the stl viewer program to see how they are done. But I have to say that every slicer and every printer will give you different results as far as texture is concerned. I am sorry I took so long to reply to this. I am trying to get more people to do this type of stuff and so post on different forums. I have developed a texture based on the Versailles pattern for stone work It is cut stone, repetitive, but without continuous mortar lines. They will not let me post it.

This is a model of the train depot in Leadville, Colorado for the Colorado Midland Railroad as it existed in 1900. The depot is no longer there. A photograph of the station is from the book "Down at the Depot". The model is in HO scale and is almost two feet long. A large number of STL files were used in printing the model. They can be downloaded from my web site at charles.dollins.org/buildings/

I have created a web site where STL files for all of the buildings can be downloaded. It is charles.dollins.org/buildings/

This is a model of a grocery store in Black Hawk, Colorado, USA. The building is still standing. On Google maps in street view you can see the odd combination of windows and doors in the back of the building. The building is now part of a casino. The plans and photos of the building were published in "The Narrow Gauge and Short Line Gazette". Thank you for looking at my work.

This is the rooming house in Black Hawk, Colorado. It has since been torn down. I tried to print clap board on the front of the house with 6" spacing. It did not turn out that way. It appears to be tonuge and groove with a 12" spacing. May try using 0.1mm layer thickness in the future to see if that turns out better. The plans were from the "Narrow Gauge and Short Line Gazette."

I have the extrusion multiplier set to 0.85mm. The width was set to auto which was 0.48mm. I think I need to increase one of these two numbers to get more material coming out to get better closure between the extruded beads. Right now I am working on putting together the the grocery store for which the parts are all printed.

The negative faceplate is brilliant. With light cuts on the tire and a sharp tool it just might all hold together. I know that PLA is very tough stuff.

Yes. You also need to know the slicer program which was Simplify3D. Different slicer programs give different results. You would need the extrusion width, which is a slicer input, to get those results.

I don't think we have ever had a drought. In the pictures of the section house in the background you can see a band in the arborvitae near the top. Deer had eaten all the leaves off the arborvitae below that band several years ago. They could not reach higher. A lot of rain and a lot of deer.

The layer thickness on the Flashforge was 0.1mm and on the Prusa 0.15mm. On the Flashforge the bricks were designed to be 2.2 mm long by 0.6 mm high. Separated by 0.3 mm. It worked well. I was using ABS. On the Prusa a brick height of 0.6mm would not work. The bricks are now 0.5mm high same as the window muntins and mullions. One bead of PLA is put down for both windows and bricks. The bricks in both cases were printed 0.3mm thick. 3 layes for ABS and 2 for PLA. The PLA is a low viscosity liquid at the extruder temperature so when the end of printing one brick the filament is retracted and then for the next brick the filament is advanced and then retracted and so on. This causes the filament to go up and down rapidly over the nearly the same region. If there is enough friction on the spool a hole will be worn in the filament and printing stops. I now use skate board ball bearing races on the spool axis. That works well.

I have thought of this many times. The problem is getting the wheel center true to the tire. If you don't do this the engine will wobble as it goes down the track. To do this you must turn and an axle in a lathe and then cut threads on the axle to hold the wheel in place. Mount the wheel without removing the axle from the lathe. You then cut the tire. The wheel will then be perfect. I am sure the plastic spokes can handle normal use during train running. The problem is the torque on the spokes during the truing of the tire. I would be interested in any ideas on this.

I bought a Prusa kit for the MK2. It came with PLA so I am now printing on my own printer using PLA. Simplify3D has a lower opinion of either PLA as opposed to ABS or of the Prusa versus the Flashforge because it will not print wall thickness smaller than 0.5 mm. Here is the side of a rooming house in Black Hawk, Colorado and the front of the grocery store next to it. The rooming house is long gone but the grocery store is now part of a casino. Both again from the "Narrow Gauge and Short Line Gazette." Thank you for looking at my work.

This was a shoe store in Black Hawk, Colorado. It is what is called a false front building. These were very common all over the west. I grew up in Champaign, Illinois and our grocery story looked exactly like this building. Three blocks in the other direction from out house was a saloon that looked like this. The bar tender also sold Popsicles so it was a favorite place for both children and drunks. The plans are from the "Narrow Gauge and Short Line Gazette." .

This is the section house at Forks Creek. The train crews would sleep on the second floor and cook, eat, and complain about railroad management on the first floor. The plans are from the "Narrow Gauge and Short Line Gazette."

Forks Creek, Colorado is long gone. Interstate 70 wiped it out, but this is a model of a restaurant owned by the railroad. Again in HO scale. These buildings were painted box car red because that is what the railroad had. It was a narrow gauge railroad out of Denver up to Georgetown. It is said that it took eleven years to build a road between Georgetown and Golden Colorado. When it was discovered that the gravel was high grade silver ore the road disappeared in three days.

This is a model of the train station in Forks Creek, Colorado, USA. It is long gone. The plans were in the "Narrow Gauge and Short Line Gazette." Also is a G gauge house, but I was afraid to get closer.

Thanks for the kind comment. This fire escape is 3-D printed. The building was not. It is on the layout of Ken Hanawalt. No idea how to rotate the picture. The bottom is on the right.
