Gilera Bi4 Nordwest 3d scanning/modelling

[Duranti]

seelvdb, marco70 and Matte, thank you all for your kind support, I sincerely appreciate it, and I'm glad you are enjoying the project! 

I'm warming up the printer right now to start printing the right hand side crank case cover, hopefully it will turn out good, I will post pictures as soon as it is finished! 

[Duranti]

This time, as promised, the right hand side crank case cover, in Gold Pearl ABS. 

The ABS is quite a bit more difficult to work with than the standard PLA material that most people 3d print with, and detailing is ok, not perfect, but good enough for the first test print of the parts. 

It does look quite good together with the right hands side crank case through, and when the bolts are in place, as well as all the small parts, it will look great!

Next are both the crank case halves in ABS. I have printed the right hand side crank case half in PLA (as shown in the pictures), but the whole engine will be printed in ABS and PC, since PLA does not like the sun very much. Stay tuned!

Just a curiosity, what about cost of the different materials (pla, abs, pc) you are using to print the engine?

[Duranti]

Hi Matte,
Here are some approximate prices in Norway for 750 gram rolls of 2.85mm filament:
PLA - 50,- Euro
ABS - 50,- Euro
PC - 70,- Euro

Generally filament is approximately the same price in Norway as in the rest of Europe I believe, but the problem in Norway is that there are only two importers of the Ultimaker filament, and they import the most basic selection of filament, but the price is good (since almost everything else is very expensive in Norway).

The import price limit in Norway, before tax is activated, is around 35 Euro (and that includes the shipping cost), so importing filament is not an advantage.
For example; if I import something that costs 36 Euro (shipping included), the government adds their own administration fee, which is minimum around 20 Euro, and tax for the item is 25% of item price and shipping cost, so the final price would be 65 Euro.

With that said; you can create a lot of parts from one roll! 
The biggest parts in the Bi4  project consume around 5-8 meters of filament, and one roll is around 90 meters, so there is a lot of fun in one roll of filament!

Ok, thanks a lot for the complete answer

[Duranti]

My pleasure Matte!

Hi friends,
Finally a milestone; I was able to assemble some parts, I got the "cylinder/cylinderhead bolts" in the post yesterday, they are M3 size (!), and I test mounted the parts, and it's looking good! 
The parts fit together very well, no tweaking, just bolt together after creating the M3 threads in the crank case.

I am now in the process of optimizing the crank case halves to get a stronger and more reliable 3d print, I will be printing the left hand side crank case half today if I get time, and I will post an update as soon as I have it ready!

It looks like the real one...........

wonderful job Duranti

Matte, marco70 and milo, thank you very much for your support, I'm happy you're enjoying the progress and seeing the miniature Bi4 come together! 

Right now I'm printing the plugs for the kick starter shaft and kick starter lever, should be finished any minute, will post pictures asap! 

[Matte]

Ok, waiting to see them.

[Duranti]

Good evening Matte!

Sorry for the delay in posting, I printed the plugs, and immediately after the print was finished I started printing a new cylinder in ABS, and then I noticed that 1:1 scale tolerances scaled down to 1:3 scale did not work well with 3d printing, I had to have a more "forgiving" tolerance. 

Anyway, the cylinder printed very well in ABS, and the surface finish is much better than PLA, which is a good thing for the project, since most parts will be made in ABS material.
Also in the pictures you can see the plugs isolated, and in place in the right hand crank case cover, and it looks pretty good. 

Tomorrow I will print the sprocket cover, and the oil pressure switch cover, both in black ABS. 

Have a good evening friends!

It's really wonderful job!!! 

I'm curious to see the final result.

Fantastic!!

great great great!

That thing is a perfect toy for every gilera's fan.
An assembly kit for christmas would be a perfect present.
A small audio chip and a little transducer will give "voice" to that model.... imagine pushing a button and hear Bi4 sound!

Now Trond, consider this: create all parts with grey ABS filament, then leave to the customer's ideas to paint those parts. In my idea this will save time and money during printing process and, by using a coating followed by two-three layers of paint will surely hide, or at least smooth, those small imperfections due to printing process.
Then appearance will be perfect.... IMHO

Look at this:

Could you tell it's a 172mm lenght model?

Would be great to 3D print all parts of a gilera saturno 1/5 scale then have fun assembling it.
