3D printing anatomic models for surgical planning

@@shibbleswentworth ok cool.

they have mesh type single layer prints that help collect the extra bits these days

contact the manufacturer :) Also it loosens and tightens counter to intuition

about 10k, very hard to find used or knockoff versions

asymmetric centrifugal mixer which basically makes a vortex inside the cup and shears the contents without introducing bubbles.

i've found these to give reasonable results for our application. it may just take more time at a certain step unless you do those. We used to do 5, 1, and 0.05 micron alumina but if you have contamination it kind of ruins the point.

saved some $ from a service call i hope.

.dxf, .dwg are pretty common

it forms PMMA polymethylmethacrylate, not sure about each component but its a monomer and catalyst for polymerization reaction.

they sell many targets you can check ted pella or emsdiasum

top is just a window, door is on the side.

solidworks

sure but this is really just used to measure cross sectional area for stress measurements. a spring is a unique geometry so i would defer analysis to load v displacement numbers which is how they are typically ordered

with an acid, methanol is just an alcohol won't do anything by itself. The ethanol in nital is basically used to keep oxygen away and distribute evenly on the surface

to get fluorescent dyes in your parts, put the dye in the IPA you are washing it in after the print. It will absorb into the surface and you don't need to add to the resin which would alter the printing process. I have done successfully with Texas Red using clear resin.

depends on a lot of things, making sure starting position is same, and no actual load is on the cell when you balance it.

yes you can also do this with some freeware, speckled spraypaint, camera with intervalometer, and matlab with Ncorr

there's a difference between science and engineering :)

I don't know if this post is still active but it really depends on what you want to observe. If you plan to observe the microstructure of the material under a microscope, you really need to use nital or picral. Anyone with the capability to polish a sample down to 0.05 um can surely etch a sample with one of these two solutions. If you want to etch it for macroscopic examination, you can try HCl. I use reagent grade and dilute it myself but I'm sure you could get away with purchasing some muriatic acid at a hardware store. For a macro etch, you can get away with about a 600 grit finish. I hope this helps. If I get any more questions, I could make a video if needed.

@@85tkern thanks buddy, really appreciate!
