Nice job sofar. Seems that you find your way in this 3d printing world. Maybe the advice below is not necessary, but I’ll give it anyway😀 I would put some time in gaining knowledge on how to print directly on the build plate. For instance the inner tub is an ideal candidate and could possibly be printed with nearly no supports at all. I don’t know what printer you are using, but here is a good start to find out: https://blog.honzamrazek.cz/2022/07/step-by-step-guide-on-perfect-bed-adhesion-and-elephant-foot-removal-in-uvtools-3/ Using his methods, I am able to print my stuff directly on the build plate, saving a ton time in support placement (and saving resin too). With respect the rear gate mesh, I would try to print it nearly upright. Any flat surface on support (nearly) parallel to the build plate will sag, so try to position your models such that you have a minimum of parallel surfaces.

Obviously I’m a fan of these Alfas. Looking good. Keep the pictures coming.

Hi gang, Long time since I posted something about my work. Hope you are all doing well. In the topic linked above I showed some pictures of the engine design I was doing. Back then I was waiting for a decent size printer (Elegoo Jupiter). After it arrived I had a big struggle to get it dialed in to deliver decent prints. Results were not always as expected: and Currently I am in the process of printing a prototype, tweaking the components as I go along. I decided on going for the 1:4 scale, giving me all the options to go for maximum detail. I did try 1:8 scale too, but this engine has a lot of small details that need to be adapted in order to get them printed in that scale. So, currently it is 1:4 scale, giving an engine that is somewhat like 35cm long. Design wise nearly everything is done, however during printing I still find things that can be improved on. Not only design wise, but also in the format of printing. For instance, I was at first planning to print the crank case as one piece, however, due to its form, it almost impossible to get a decent print. Even here I already cut the larger parts protruding from the sides of the crank case. I have cut off the wings, the flange that connect to the oil pump and the compressor, the tray that supports the generator and the gears house that connects the generator to the crank. Furthermore I have divided the remaining crank house in 2 pieces. The result is many parts that can be printed upright directly on the build plate, allowing for a minimum of supports during the print process. (Previously I was losing nearly 50% extra resin for supports of the crank case during printing). After some more tweaking I got result (finally, I'd might add). Following pictures show, what I have now all temporarily fixed together. First pictures shows calipers reading too to give an idea about the size of the components. Everything fits nicely. The 2 main crankcase parts have been glued so form oine part now. The rest is as on the original engine. two 4-cylinder blocks, fixed together in the middle with bolts, two cylinder heads, again fixed together with bolts in the middle. Bolts are not yet printed and thus are missing in these pictures. The oil pan is big and I failed to get it printed in an angle. Too much distortion. I modified the design such that it could be printed flat on the build plate: Valve covers were also modified to be able to print them flat: That gave a perfect result. Below the oil pan and the valve cover in situ. Time to start with the separate parts; Compressor: The crankcase vents and a bearing cover The carburettor: The goose neck and the front air intake. The latter is the most difficult part to print. Not possible to put it flat on the build plate and difficult to support properly. However I did manage to get a decent print: Crank case with vents in place: Compressor and carb assembly: The gap between the flange at the right side and the compressor body is there because I still need to print the brass gasket that is located there on the real engine. The blue circle indicates a small error in the print. A small detail failed to print but can be added easily. Many parts to follow, but that is for a different time. Need to do some prep work first. I also bought a Silhouette Curio as I need to cut gaskets from sheets. Nearly all components need gaskets, for which I allowed sufficient space in my design. I'll use thick brown paper to cut these. I started this to be able to build a display model for myself, however, if there is interest, I might sell some copies in the future. Not decided yet. Need to think about it and also about the form I will be selling them in (as a kit or completely built and painted, or both).

I see you got the paintshop to correct their stupid mistake with the drive shaft🤪 Nice work!

Hat off for the fine work you are doing, Thierry

Beautiful work, Jörgen

excellent execution, fabulous work, Luca.

Yes, I just noticed the scenery around the model. Makes it like a real workshop

So much reality. Fantastic paint work. Love it!

Cool! Well done!

Your love for details shows brightly in all your work, Dan. I love your love for details 😉

Nice work on the dash, Nick. One remark though (just nit picking as you probably won’t see in when all is mounted. It seems the radio is a bit out of alignment (might be caused by the way the picture was taken).

Well Dan, you are creating a master piece (again). Beautiful craftsmanship👍

nice Thierry. Wonder what you are going to modify with this model.

That engine already looks great. The corrugated hoses, create a lot of reality

Looking very smart! Love the paintwork.

It is quite unbelievable that those tires were done like that. Youve corrected that one. It is indeed a very big model. Shows how big the car has been 1:1.

Pff, luckily he pointed this out at this time.

Olivier, this is a really fantastic model. You have managed to bring so much reality into it. Like Jeroen said, even the close-ups do not clearly show that this is “just” a model. Well done and it looks great on display next to the Fiat.

As always, the level of detail in your creation in mind blowing. Fantastic, Dan!

No lack of patience and perseverance with you so I know you will get there, Thierry.

Didn’t you know Olivier has a cutting mat in 12:1 scale on the floor of his garage? Looking seriously good, Olivier

Indeed a very interesting project. Didn’t know that Danbury ever made 1:12 scale models. I always like the Danbury’s more than the FM models.

The dash looks good to me, although I did not compare it to the real thing. What is the thickness off the material after printing? I indeed see this warping happening with very thin printed items. Strengthening at unseen places tend to remediate this.

Lovely work. I wonder why you waited for Revell (in this case) to produce the T2 model. The reason is that you probably will modify 95% of the kit, so why bother with a kit😉 Interesting build and I will follow it to the end (what year according to your planning?) Nice work sofar. 👍
