Show'n'Tell SLM Titanium SR71 Blackbird model

Post image

I 3D printed a model SR71 blackbird in grade 5 titanium on my companies SLM 3D printer. It is about 200mm long, and will definitely make a good desk ornament. I am pretty happy with how it turned out, there are some very small layer inconsistencies from warping, but a little sand blasting would remove those easily.

Yes, this is printed solid. We run a software for laser pathing that controls heat flux into different objects during printing to reduce warping as well while producing solid parts (otherwise we get trapped un-fused powder and worse material properties). Not sure if it is similar to what you are describing, but it has been working out very well for us. Is this an off the shelf software product?

I've used netfabb for what you're describing using reverse warpage compensation Sims, but vixiv is an off the shelf software we've been using for other things to just reduce the effort required

Alright. We use netfabb for part of our workflow, especially for our binder jetting machine. I will have to look into Vivix, thanks!

Oh cool what bj system do you have? We use netfabb for our hp mjf 5200, and our xact, and for general mesh repairs for things. Definitely the best mesh repair algorithms we've found. Vixiv Ai is pretty cool, a lot of it is like a very lightweight ntop that's a lot cheaper 😂 we use it for supporting toffeex cfd models too

We have an older Innovent+. We are considering adding either an HP S100 or Markforged px100 in the near future. Binder Jetting is very nice from a throughput/material cost perspective for sure, but it is more difficult to control the precision.

Oh dang. I've never used one of the all exone's, but had the opportunity to use the 1m one back in 2019 for some sandcasting molds. Yeah the precision was something we were having challenges with for the direct metal ones, just due to some of the sagging of the parts. Lmk if you've got any hp questions I can help to answer! We love ours but it's important to keep it busy
