done for tonight..

step by step

First shapes of the engine.

Hi all, Having recieved my new 12K 3d printer, I might as well try something a bit more ambitious. This is what I'm going for. It might blow up in my face, but at least it will be a good learning project. I bought a simple pre made 3d model which I will use as a base. Starting work on the HE S 011 jet engine.

This should do

Ps. It takes me about 30 mins to draw up a part in 3d and approx. 1 hour to print it. I do however have a lot of failed prints, but theyre all to blame on my inexperience.

As far as i know PLA printers are great for printing household objects and engineering / industrial design mock ups. There is a reason model companies all use resin printers for small detail prints. You simply can’t match the detail in resin with PLA.

First prints. Also designed a new spinner backplate since the ZM one lacks all detail.

This will be a great little test for the new printer. The Ratier 1527/1528 prop with the spinner removed shows this intricate prop hub. Diameter will be 1cm.

Got a new 3D printer. Old 4k one on the right, new 12k one on the left.

Aaand the mk103 gun is done. Printed another piece. A connector box at the rear that houses a number of wires. Reference from the proper angle is scarce. also printed a shitload of hatches in various shapes. You cannoot scratch this kind of detail.

Getting there. Basic colours are on. Needs more wiring and a few more details.

Succes. The pressure air tanks came out nice.

Just noticed I screwed up with the screws. Fixed.

final part. The barrel clamp that holds the barrel in place. Tiny tiny part, so interesting to see whether the printer can do tis. Asking for trouble...

Ok. So slowly getting there. I think i reprinted every part 10 times. At least. The ejector came out perfect in one go though.

Discovered I forgot to model and print the ejector chute. Managed to find one or two lousy photo's that show this part.

The annoying thing is that ZM did make the mk103 cannon but never released if in a Hs129 b2 kit.

Finally happy with all the parts. Added eyelits to the mount that fit the eyelits on the mk103. Some black paint as a base.

Sure looks like it doesn’t it?

Here’s the printed mk103. Even thought the barrel end came out nice, the master barrel is way nicer so i replaced it. almost ready for paint!

Just bought another brass barrel for this gun. This one has a locating pin at the base which makes it easier to insert into the 3d print

First print looks succesful.
