What can you achieve with a simple 3D printer nowadays? I used Julius’ recent drawings of the coal fired version of a steam locomotive NCS-76 of The Dutch Railways to see just what can be done.

Some cross sections were added to show the interior of boiler, ash-pan, water-tube, preheater and cylinders.

I used Julius’ .PDF drawings, changed them into PTC-Creo Elements format and translated all into .STL files.

Some of his detail-drawings needed modification to make 3D printing possible and/or easier.

I used the Cura slicer and Creality 'CR-5 Pro_H'  for printing.

This model consists of (98%) 3D printed parts in PLA (Bronze, Black, Green and Silver).

It has more than 550 separate printed parts that are assembled and fixed with  stainless steel fasteners and brass threaded inserts. No glue was used, except for the red copper boiler rivets.

Brass hand-rails and supports are purchased parts.

Model scale: 1:11.3 (Gauge 127mm/5inch)

Dimensions: L1105xW270xH413 mm.

Total Weight: 8 kgs.

3D modelling time: Many hours 🤒

Total printing time: 860 hours

The tender will be realized in 2023.
