  1. Ohh great. Love to see that one finished (and my guess is that you would like to see it finished too)
  2. Good to see you on the forum again, Olivier. Your biker looks great. Well done. Thanks for your best wishes and the same for you and your loved ones.
  3. Good day to you all. In the vehicle section I have posted the results of my first complex 3D build. You can find it here and in that thread you will also find a link to the WIP concerning this build. Let me know what you think.
  4. Thank you, Jeroen. For me it started after retiring, first finally finishing the AR Coupe Elegant and then asking myself: Now what. Decided it might be fun to do something I never did before. In working life I always enjoyed working on (for me) new things I never did before.
  5. Thank you Spiny. Clean up, you ask? Well there are all kinds of cleanup involved when printing with resin. Firstly getting rid of uncured, unneeded resin. Then supports needed to get parts printed need to be removed. Then, depending on the resolution of the printer you need to get rid of voxel lines, printer resolution artifacts. The parts I printed on the Jupiter had lots of these artifacts and thus needed a lot of cleanup. Some of the detail pictures above show these, because there were areas where removal was next to impossible. Anyway, glad you like it too.
  6. Took me some time to catch up, but this is becoming a fantastic model. I think the wheathering of the floor looks realistic. Yes, probably there are many 1:1 cars that have a lot more rust, but I agree that it would be shame to try to replicate that. The model is clearly a well maintained car so this works well. You are showing in great detail how you are creating this model. Kudos for sharing that with us.
  7. Thierry, you keep at it until it is perfect and that shows. Hat off (again) for your perseverance and eye for details.
  8. Good afternoon (morning or evening, depending on where you are). It is time to wrap this build up, because the beast is done. I created the advance retard mechanics and installed it on the engine. Parts are mainly old-school modelling with thin alu and a bit of plastic. This picture also shows clearly the manufacturers plate on the distributor. I've also added the two hat nuts on top of the valve cover thus fixating the A/R mechanism. I've added the missing nuts, bolts and screws and with that the model is finished. I'll show some pictures here and make a thread in the RFI section to show the end result in more detail. That's it. See the complete results in the RFI thread: Thanks for watching and all your comments and support.
  9. Goodday friends, I embarked on this journey without having any knowledge about CAD design and even less experience with software that will allow one (or in this case me) to design a model. After finishing up the build of my Alfa 8C2300 Coupe Elegant I thought that there was much to improve on the engine. So first thoughts were to design the engine in 1/8th scale. First steps where to select the software with which I was going to design and gather all reference material that I could get my hands on. Software wise I tried Fusion360 but found the learning curve too steep and als didn't like that I had to do it all on my PC. Nick mentioned somewhere at the start of his 3D endeavors that he use Shapr3D on the ipad. I know he ditched that in favor of Fusion360, but I decided to give it a try. I found this to be much, much easier to learn. So this made starting 3D designs fun. But where do you start, how to get proper dimensions in all directions. Well, luckily there are pictures of the gaskets in between the components that make up this engine, so that gave a perfect starting point for all measurements in the x/y plane. Reference pictures of the engine gave me the missing info in the z-plane. This helped enormously to get this design underway, however lots of issues and challenges found their way into the design process (of course, I might add). Many of these issues had to do with the learn as you go process. Working with software that you are completely new to, that is also in development with new functionality being added in a monthly schedule, doesn't make it any easier. Shapr3D is a direct modeling tool. It does not give you a time line, like parametric modelling tools such as Fusion360. You have an undo function that can be used to undo changes within the session you are working in, but that does not carry over when you close the session. Currently in beta they do introduce parametric modelling, but 2 years ago that didn't help me and so I ended up with my model being design without any history other then the versions I created along the way. Has this proven to be a big issue? No, mostly not. I have always been able to revisit any part of the design and modify that without major issues. OK, having said that. I finished up (so I thought) the design early this year, and started the printing process. I had 2 printers back then. The Elegoo Jupiter and 2 Phrozen mini8k. I found that printing on the Jupiter was not easy at al. Lots of failures and when not then the results were sub-par. Way to rough surfaces for what resin printers can produce today. Printing in 1/8th scale was actually not possible. My designs had too many "flimsy" details that simply would not come out correctly on the printers, so I changed to 1/4th scale. That worked much, much better. I ended up printing just the gear box body and the oil pan on the Jupiter. The rest was printed on the Mini8K's, which produce really smooth surfaces. Even the crank case, which is the biggest part of the engine was printed on the Mini8, but only after cutting it in 4 parts (2 "wings and a front and rear part). Come to think of it, the wings on this model were printed on the Jupiter. During summer I sold the Jupiter and ordered an Elegoo Saturn 3 Ultra, which gives much, much prettier results than the Jupiter and even in way less time too. Anyway, designs ready and printed. In all, counting all nuts and bolts the model comprises some 600 parts. All parts cleaned and painted and then assembled resulted in this: https://www.ponipics.nl/8C2300/sDSC2785.jpg That's it. I'm really happy with the result. So what now, you might ask. Well, there are some updates needed to improve fit and printability of the parts. After that I will create a new model in 1/4th scale. While building it I will make sure that I properly document every step. If I find that the process is sufficiently repeatable, I will create parts for a number of models to be purchased by those who are interested (I already have some requests). But I think the bigger market will be in a 1/8th scale model that will fit in the Pocher Alfa models. In order to get there I will need to modify the design to get rid of the "flimsiness" (is that even a word?). Anyway, there is still a lot to do before we get there. To sum this whole build up: 1. I learned a lot about drawing complex 3D designs 2. I learned a lot about placement, orientation, supporting and printing the design. 3. I did not really keep track of all hours I put into the design of the engine but it must be way over 400 hours (and still not finished). 4. It was fun to be able to do this and finally get this result. Here's a link to the Work In Progress thread for this build: That's it friends. I hope you like it. Let me know what you think.
