I guess the majority of modellers, who crossed the inhibition level to buy a 1/32 B-17 (size- and pricewise ) already got the HKM model (at least I did ), so no, please not "another" B-17. But I would very welcome other WW2 subjects from WNW that haven't been done yet. I would really like a 1/32 Battle, Fulmar or Defiant, though those seem rather unlikely from WNW. Alex

I'm afraid you missed the late style Dora tail wheel. Just kidding, splendid work!

Very nice, especially the chipping

Here are printed landing gears from a weird project that distracts me from my already ongoing builds. The "leg" is printed as one single part with the Anycubic Photon. The tires consist of two halves, created with a conventional FDM printer, which could be easily sanded when put on a Dremel. Cheers Alex

You could try to print it that way, maybe only with supports around the lower edge. Perhaps it will fail, but to a certain degree, overhanging objects can be printed without support, so who knows how it tourns out

The cylinders took a bit more than 2 hours. The cool thing about this kind of printer (called DLP printer) is, that at every step, alwas one complete layer is created by the UV display at the same time, no matter how big the part is. That means that it doesn't matter if you print just one cylinder, or in my case 20 at once. In both cases, it would take about 2 hours with my settings. Including the small support struts, the cylinders are about 1,6 cm high. According to the printig software, the main center part of the engine takes 3:45 hours with a layer hight of 0,04 mm. In reality, it might take a little bit longer, but not much. That part is a bit less than 3,5 cm high. So in just a few hours, one complete engine can be printed. Cheers Alex

Hi Gary, in fact, I haven't done any post processing concerning the surface. I just removed the bottom support structures, and washed the parts in isopropyl alcohol. Finally the parts layed a few minutes under a uv lamp to harden the parts more. The parts were printed with a layer hight of 0,04 mm. Cheers Alex

Hi Rick, thanks! My settings are: Normal exposure time (s): 16 Off time (s): 0 Bottom exposre time (s) 90 Bottom layers: 8 I haven't tried if other settings would lead to reasonable results in shorter time, but with those settings, my printed parts with this resin turned out nice so far. And for me as a hobbyist, time isn't really a critical factor. But even with those settings, the prints go pretty fast. One batch of cylinder takes just a bit more than two hours. Here is a overview with recommended settings from other Anycubic users: https://docs.google.com/spreadsheets/d/1crvzMnt_8NJXAsABinoIhcOjE8l3h7s0L82Zlh1vkL8/edit#gid=0

As Rick (SCRATCH BUILDER) said, somehow you have to outsmart gravity. Actually you can print at a certain overhanging angele, and even some vertical areas without support below. But to longer the distance, the higher the risk of a failed print. For example, if this engine would be printed as one part, the thin pushrods (0,7 mm diameter) would lay pretty flat "in the air", only connected to the main engine at both ends. I havent tried yet, but I suppose such a print wouldn't look great. You could add support-structure under those areas in the printing software, but it would be a pain to remove the support after printing. And as you said, it propably makes painting easier

Hi there, I want to share some experience with my Anycubic Photon 3d printer. I read some positive comments about the Phrozen ABS like grey resin. I gave it a try, and made a radial engine. Here, the various cylinders are sticking on the print plate, still covered with liquid resin. They all sit on support struts, which can be easily removed after printing. After cleaning in Isopropyl alcohol, that’s how it turned out. The whole diameter of the engine is about 4 cm. Looks promising for a 400 € printer Cheers Alex

I don't dare to say, but the engine cowlings were made of deodorant covers The forward parts of the cowlings, as well as the wheels, were my very first steps in 3d-printing. For the engines, there are very nice resin Bristol Pegasus/Alfa Romeo 126 RC.34 engines from Vector.

Hi Padraic, thanks. For the diamond plates there are corresponding styrene plates available: https://www.architekturbedarf.de/katalog/search?mode=check&do=riffelblech Cheers Alex

I would very much welcome a Martin turret, since this somehow prevents me to continue with my Marauder project at the moment. Apart from some photos, I found no real drawings of that turret. Did they use the same turret on the A-20G? In that case, the recently announced kit from HGW might help out Cheers Alex

Great news

I wasn't aware that cigarette ash is used for polishing, but this sounds like a good reason to start smoking as a New Year's resolution Cheers Alex
