Mine was Charles Perkins.  Wood was head of engineering graphics back then, which assumed a larger role as CAD came into play.

In our pre-project class, we had to use NASTRAN on a VAX and you had to enter the material data in a "comma matrix" form for each element of the structure.  It was horribad just from a data entry/error standpoint.  You'd submit your model to the processor in a batch-processing mode and then watch it complete or error out.  Lotsa "fuuuuuuucks" and "yessss" while watching that.

It's funny how the same patterns of computing can emerge across different disciplines. There's a lot of processes like model training or large deployments that are still "submit and sit" where there's not much for you to do, but it can be helpful to be on hand to terminate early or catch a late error due to some deep buried parameters

$600 to be able to print CF nylon with a heated chamber is pretty hard to beat. One thing to consider is that Nylon, ABS, and a few other materials off gas VOC's when heated for printing, so be sure to have excellent ventilation or not set it up where people tend to be. 

I found a pretty thorough review of that printer, and it looks like it'll be a solid prototyping machine.

Do you have much experience with FDM 3D printing?

None. Probably going to try starting out with some Christmas ornaments and hot wheels ramps and stuff.

thats dope shit.  where are you getting the models from?  ive got orange filament right now, and been printing a ton of halloween related decorations and accessories

Most of these were kind of generic ones off of thingiverse or printables, but I made a lot of modifications.  Mostly adding the colors. Painting the stadium was a bitch.  Putting in the "1" in the tower was also pretty time consuming.  I think I remember paying for the DKR original file on some website that sold STLs, think it was like 3 bucks. I can see if I still have the files of the finished models if you want.

I'll be damned, I should check out Cults3D more often! Added to cart

If you have the filament painted version handy that would be allsome to have

Yep, that's the one I got.  3 bucks, just like I remembered.  I'll see if I can dig up the file.

This thing is bigger than I had pictured in my head.

That's a beast.  I've seen some really good reviews on this model.

Did my first print of something that wasn't preloaded on the printer last night. Took me a bit because the flash drive that came with it was corrupted and wouldn't even format. Anyhow,  I eventually found another one and was able to download the firmware updates and stuff and figure out how to use the slicer to print this guy. The first time I tried to print it without supports because I didn't think about the hands or back of the helmet hanging down. Stopped it and resliced it and got a pretty decent print. Gonna have to figure out how to fine tube the settings, but so far it has been pretty much plug and play.

So what’s the melting point of the finished product? Could you use this for lost wax casting?

[NotActuallyALonghorn 4974]

Look up lost PLA casting.

Oh man, there's a BUNCH of YouTube videos on this. Everything from PLA to some tailor-blended filaments for burn-out. But yeah aluminum, copper, and bronze all play really nicely with the process

 

The really crazy stuff is the SLA (stereolithography) printers that get micron layer heights.

I really recommend OrcaSlicer for its built in tuning prints that are really helpful for building a filament profile. Covers everything from temperature towers, to pressure advance, to max flow rate calibrations. That's definitely more nitty gritty, but it's nice for tuning

This could be a huge opportunity for someone. I’m involved in a niche hobby that relies on castings. And the suppliers and people that know how to do it are all retiring or passing on.

If you're in the Houston area I'd be happy to run some prints for you, or chat with you on how to get it set up yourself. Bambu's A1 is awesome at $250, and has a filament switcher bundle option for $400 if you need multicolor or multi filament

I figure I'll mess around with the native software enough to kinda get a feel for things and then venture out to the other stuff once I've got an idea of what I'm doing.

Check out some of the advanced settings in your slicer - one that Orca and Bambu slicer have that I LOVE is variable layer heights. So for each model, it will dynamically adjust layer height to best suit the geometry. If it's a curve, it gets really thin layers - straight walls get thicker layers. It's shaved nearly an hour off of prints in some cases for me, without negatively impacting quality or strength

ftFresh off the printer.

Prusa just announced their CoreXY printer, and in true fashion, are offering an upgrade path for Mk4S owners. Temp controlled chamber is a nice feature
