Yep, that’s the one.

Reminds me a bit of the mosquito girl from one punch man XD only a bit… @Thom thanks!
-
CAD and printing by me, so yes thanks!

It has been a while. I‘ve been fiddling with the VF-9 again and decided I need a test print to check if everything is fitting. I only need to decide what to do with the main landing gear. Anyway… pictures. And a size comparison.

shapeways is basically sunset. I think another company purchased them, but not sure if they'll continue most of the services.

It is crazy how much sanding the 1/48 VF-1 needs. I am building a VF-1J at the moment, and man ... I am not happy.

happy happy joy joy

Oh yes ... the game is horrible to play, especially with the tight time limit to missions. I managed to churn through it anyway. I just recently restored my DC and played the game.

oooh ... sexy I played Delta yesterday on my Vita TV. First two extra missions and the first Delta mission, and I purchased the destroid, and got my first two trophies. haha The controls are a bit weird to me at the moment, but I like the way things are animated in Delta Scramble. Has more of an anime like vibe, exaggerating physics and so on.

Well, yes - both is right. I'll try to explain it. Oxygen can form "free radicals" (not sure if this is the proper English term for that here, correct me if I am wrong, please). Basically, the double binding electrons in the 2p orbitals of O2 (usually a stable bond) can break with added energy (e.g. UV light). Both oxygen atoms have two spaces for valence electrons in the 2p orbital, but they cannot be filled permanently (not the most scientific accurate explanation here). So both atoms "fight" for a neutral state. The stable state would be to have only one electron in the valence electron binding with the same spin. In case you add energy (the UV light), exciting the outer electrons, they start to switch around, and bam... you can oxidize things. That makes oxygen so much fun to work with. Fun fact: due to this behavior, human body cells degrade. What keeps you alive, slowly unalives you as well. So - what happens with the yellowing? The polymer chains in plastic are degrading. Plastic consists of chains of molecules. The bond between those chains breaks and forms other bonds, so your polymer plastic degrades to lesser polymers or monomers with different color and different properties. Even those monomers can break down. If your plastic is exposed to oxygen (like in air, the gas), the degrading is getting faster. Even if there is no oxygen (again, in the air surrounding the plastic, not the oxygen in the polycarbonate), yellowing can happen due to unstable bonds in the polymers. So - in any case, your plastic will slowly degrade and decompose due to subatomic effects. The process is speed up by external energy in form of UV light, heat or other forms of radiation. Energy added to the oxygen "radicalizes" the oxygen, and then the free radicals break the (stable and meta stable) bonds. So what do we learn from the above? Keep your plastics stored in a low energy, low oxidizing agent environment to slow down degradation. (read: in a box in a cold basement) @F18LEGIOSS2 Use UltiMaker Cura. That should do the trick.

ah good good good ... finally me studying chemistry is helpful. Peroxide (I assume hydrogenperoxide, H2O2) is an acid and a heavy oxidizing agent. I can easily break down any organic compounds. Most decals (let's think waterslide decals first) use light adhesives and carriers. Those will absolutely be dissolved by H2O2. Depending on the material used, you can be sure that H2O2 has an effect on it. Expect your decals to at least be discolored due to the color oxidizing. From there it only goes downhill: reduced adhesion, decal lifting or peeling, or destruction of the decals. If you really want to be sure, use low concentration H2O2 and UV lights to recover yellowed plastics. There is no guarantee though. You might want to investigate on how to remove and re-apply tampo decals. Background: The plastic is yellowing due to UV light. It is breaking down or altering the polycarbonate plastic, causing bonds in the plastics that break light differently and therefore giving it the characteristic yellow color. The H2O2 process "reverting" the effect by simply bleaching the yellowed layer of plastic. It is not repairing the plastic to it's old structure. UV impacted plastic can be more brittle. As far as I know, the process wouldn't speed up yellowing. It is just that plastic layers under the top layer might already be impacted slightly by UV light, and if they are kept under UV exposure, they would yellow as well, giving the impression the yellowing is speeding up.

Lol… hahahhaha

@MechTech my condolences @electric indigo 1/72? You got too much money… hahahah PRIME TIME! did some priming along the seams, just to check where to sand.

Quality and gameplay wise, I think the DYRL hybrid pack game was even better than macross 30.
