Gilera Bi4 Nordwest 3d scanning/modelling

[Matte]

I kit tamiya in 1/12 (ed i pochi in 1/6) sono il top in campo plastimodellistico . Trond is doing something of similar, except perhaps for the surface finishing, but it's absolutely normal. And he is creating a little jewel :mot


PS: the idea of Big (using the same material for all parts) I think is really good, if you want to produce and sell some kits of your engine.

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.

Thank you for the inspiration and enthusiasm yumax, bigbore and Matte, I sincerely appreciate it!

The R1M model is absolutely incredible, truly an amazing piece of downscaling, Tamiya have always been masters of the art of scale modelling!

The surface quality of the Bi4 model would be better with a more advanced 3D printer, especially a Stereolithography printer would make for incredible prints, but those printers are sadly beyond my wallet size these days (running a one person engineering company in Norway is not very lucrative, haha).

An all-grey model to allow for customers to paint it themselves would make for a great surface finish, a very good idea bigbore, I will definitely consider that! 
A sound module would also be very cool, and indeed a great addition to a project like this, and it would be relatively easy to implement, I know that for example Tamiya has those available from their truck range, I will investigate.

I have a few Saturno parts laying around, and I was seriously thinking about building a Saturno racebike some time ago, but finding parts is difficult so I cancelled the project.
A 1:5 scale Saturno though, would be serious fun to put together, and I would love to have one standing on the shelf! Some day if I manage to get hold of a Saturno restoration project, I will take it apart, and scan the parts! 

I printed the sprocket cover today, it came out pretty good, some small defects, nothing I can't fix with adjusting the print settings. Right now I'm printing the cambelt cover in ABS, I have made some small modifications to get it to fit perfectly, I will post pictures when it's finished!

can't be worse than running a one man IT company in italy 

[Duranti]

bigbore, you are probably right.  
We are living in times where there are too many people/companies competing for the same jobs, it's very difficult to stand out from the crowd. In Norway it's very common that the people who get the jobs, are in family (or friends) with the employers, and outsiders (like me) have a painful time trying just to stay afloat, sadly it's probably the same everywhere.


In my hand I have the new ABS cambelt cover on the left, and the PC cambelt cover on the right, somehow the ABS gives better detailing with the same accuracy setting. The ABS is more matt than PC, and not as strong, but I prefer detailing over strength in this case, so for now I will use the ABS cover. 
The print looks abit coarse in the picture, but in reality it is quite smooth, the layer thickness is 0.15mm! On convex surfaces (like the alternator cover) the layerlines are more apparent, but still pretty smooth.
Tomorrow I will print the left hand side crank case half, then the engine will have all the major components in place, should be interesting to see!

Hi Duranti,
Talking about the cost, nowadays how much did you spent for realise this model?

By your opinion is it possible replay the model for sell it?

Bello!

[Duranti]

Hi yumax,
Sorry for the delayed reply, I turned off the pc early yesterday. 

Regarding cost, well, it's difficult to put a price on the work that has been done this far on the 3D CAD model and 1:3 scale model, I have spent around 4 months, on and off, around 300 hours to get to the results of today. But, it is important to remember that this is a pure enthusiast project, time and money spent can never be justified when it comes to enthusiast projects! 

The 1:3 scale model is definitely possible to replicate, no problem, it takes time though, and filament; approximate time spent to 3d print a whole engine (with 10% infill) would be around 60 hours, and filament usage is around 1 roll of filament.

The cost of a complete engine is difficult to decide as it is a labour of love, rather than something to earn money from, perhaps we could make a poll and collectively decide? 


It's great fun to see so many Gilera fans appreciate this project and the resulting 1:3 scale engine, thank you all!

Duranti, my congratulations, very good project and done really well!!!!!

Valter,
Thank you very much for your positive and inspiring comment! 

I am warming up the printer right now to start printing the left hand side crank case half, tonight I will post the results! 

[marco70]

Congratulations great work   
How much would it cost to buy one?

marco70,
Thank you for your kind comment, I really appreciate it! 

I will make a summary at the end of the build, and we will get a better overview of what is possible with regards to price, hopefully it will be possible to sell a kit for a price that most enthusiasts can justify paying for a scaled down Bi4.
Also; a poll to decide a price would be interesting.

Hi guy, thanks for replay,
for sure the bill, considering the spent time, it will be enormous, is the reason why you should consider to make some profit producing some quantity of this model.

For sure, when and if you will consider to "produce" the model, you could count on the fans of Bi4 in this forum.
My suggestion, in case, is to count as soon as possible the possible adhesion on project.
Never say never you know!!

[Duranti]

Good evening yumax,
Thank you very much for your encouraging words, I appreciate it!

If I can manage to achieve a model of high enough quality to be able to sell it, I will for sure consider selling some kits to enthusiasts who would want to own a 1:3 scale Bi4!

With that in mind, I will follow your advice yumax; If anyone is interested (no commitment) in owning a kit, let me know in a PM, thank you. 


It looks like the left hand side crank case half will be finished during this night, I will post pictures tomorrow. 
Have a good evening friends!

[Duranti]

Left hand crank case half is ready, almost, well, it finished yesterday night, and when checking the results this morning I realized that the G-code was not perfect, the sprocket area was sadly not correct..
I am currently printing a new piece, with small alterations implemented, hopefully it will turn out good!

Below are some pictures of the crank case half, it looks pretty good, the grey ABS prints better than both the black ABS and gold ABS, I do not know why as they should print with the same results, but the grey has better detailing and smoother surface with the same settings applied in the CURA software. The other lighter grey parts are printed in PLA, but will eventually be replaced by ABS pieces.

Anyway, I hope you enjoy the pictures, it's getting closer to the finishline!
