I thought it might be of interest to show my latest C-170B, 1:36 scale model that I have printed on my Prusa Mk4 FDA printer. I spent quite a bit of time experimenting with dividing up the plane into parts that suited FDA printing. I am now quite pleased that you can get quite decent results in the end. All the parts have been 3-D printed except the undercarriage legs which would have been too flimsy to take the weight when sitting on a surface. They have been made from thin aluminum alloy sheet.  Even these would have been ok printed, if the model was only to be kept on a stand. I was particularly please to get good accuracy with the propeller and tail wheel which required

reasonably crisp detail. 53896739263_d03699bc98_z.jpg

I have always been a scratch builder and therefore been able to choose whatever scale I liked. I have found that 1:36 is quite good for general aviation planes. 

For the record, my other preferred scales are 1:50 for WW2 fighters and 1:100 for larger aircraft.   I have scratch built a DH Mosquito in 1:50 and a Sunderland Mk5 flying boat in 1:100. I can present photos of these if anyone in interested.

 

Back to the C170, I have now made up one more as shown in the photo here.  As it is derived from a 3-D CAD model, I can print the parts in any scale I wish.  I actually have a C170 weather vane on the house roof that is 1:28 scale.

 

I'm still not sure what planes I will model up next as doing the CAD work can be quite daunting! 

 

BTW I continue to be very happy with the results from my Prusa MK4 printer and with the latest upgrade as it can do very accurate small detailed parts.

Gregair, this may interest you.  I have now gone ahead and pretty well done all the CAD work for a Cessna 185 and am now putting one together at my favorite light aircraft scale of 1:36. Of course with CAD and 3-D printing the scale can be anything. I always do the CAD work at full scale and then set the final scale in the Slicer software.

 

The fuselage is divided into three parts and wings and tail are printed vertically - all to suit using a FDA, 3-D printer. The propeller, wheels and struts are printed in one set.

 

I may create a new topic for the interest of others when I finish the first sample that would provide more info.

 

And finally a pic of the finished model!
