Nice having access to CNC machines and 3D printers. I can use machinery at my work to make components when i need them, so handy! Just wish they had use for a 3D printer!

My work has been investigating 3D metal printing for the last 4-5 years, but due to the cost nothing much has really come of it. There are only a few companies this far down under that do it, and is mostly titanium components for F1 or for medical, not much in any alloy steels. When they finally find it cheap enough to buy and manufacture something i will probably be out of the modding game altogether lol.

My company also looked at a metal printing machine. Not sure if we will ever get one but they are cool. I work in the space industry and we don't really fly any printed parts. That may have more to do with us being old fashioned though. The coolest thing I've seen one make was a stainless steel pyramid where two of the faces were magnetic and the other two weren't. Mixing metals on a single part really opens up design options.
Mixed materials is pretty cool!

From the seminars i have been to about it with members of the US defense force and other similar lecturers i think they arent used for aerospace due to the nature of the manufacture. 3D metal printing is essentially laser welding so there is the risk of inclusions and other imperfections that can be introduced by the welding process. You can x-ray and other testing methods but i am not sure about whether they would hang it all on a part that was manufactured that way. At least maybe not with the current machines anyway. Great for manufacturing other non life critical components though!

Interesting, we machine components out of Grade 5 Ti and never had any issues with sparks or fires, but we do use high pressure flood coolant on our machines. Is it the grade that's flammable?
It is a mongrel to machine though, have to make sure the tools are sharp and have the speeds and feeds just right or it starts galling on the tooling.

IMHO while i am no expert i think you are getting hung up on using the stock filter. To get the car running i would seriously think about using a cone filter and then think about the details of trying to make it look more stock. As soon as you try and run a hood scoop or piping to face another way you are in non standard territory anyway. If you want the outside to look stock and the inside semi stock it seems the simplest way for now. You should still be able to get just a long enough section to run a MAF if you put it to the side wheel well, probably colder air there too

Loving the build thread though, making me jealous i cant do something similar... and never will with the way gas prices are going :rolleyes: :)

You should be fairly safe 3D printing in Nylon (PA), most of the black plastic parts in engine bays at the moment are a glass fibre reinforced injection moulded version. Melt temperature is up around 260-300C (500-570F for you guys).

Nice to see it nearly finished!

I had been wondering about the oil filter location, it looks nice and easy to get to, but I would expect when you unscrew it the oil would pour out from inside the filter and down the block or ancillaries? At least if it is hanging down the oil is contained inside the filter... or does the oil drain out into the engine before you get a chance to unscrew it on those?

Interesting, guess as the LS isn't that common over here i have never had to work on one, if it all drains out then I guess it isn't a problem really. Yeah the factory JZ location sucks, its a PITA to get to let alone the mess it makes.
