Interested in collaborative investigation of arterial pulse wave mechanics via 3D printed experimental models and high fidelity circulatory systems

[Bruce Guest @slonold42]

Poster finally done! @ArterySociety Excited and a little daunted to be heading to #ARTERY2022. Hoping for input on my quest for ever better #arterialphantoms, #arterialmechanics, #pulsewave.

Tensile Tester Finally has a Pulse! https://t.co/WTRmukMFVt via @YouTube It has been a long,twisty road but moving again. A little more functional testing/development then dig into @FullControlXYZ to scheme up some physiologic artery wall designs and on to the 3D printing fun!

[Bruce Guest @slonold42]

Exciting to see the multiplanar progress you and your team are making!! Inspires confidence that there is a viable path to printing physical arterial models with realistic mechanical properties AND important anatomy like the aortic arch - just a "few tweaks" to go!

[FullControlXYZ @FullControlXYZ]

Thank you @The_SMF_ for such an awesome SMRRF! And thanks to all my awesome students and @Duet3D to get this 4-axis system up and running. It was so amazing to be at a reprap festival. So many positive people with great ideas!

[Bruce Guest @slonold42]

@DZeggelaar Well done!!!

Having printed with 60A TPU from various vendors for a few years now, can say that @Coex3D 60A filament is excellent as is their customer service!

[COEX 3D @Coex3D]

Have you wanted to try printing with CoexFlex™ 60A TPU but weren't sure if you could handle it? Check out our new in-depth guide for everything related to printing with this ultra-soft flexible filament!

#FullControlXYZ is out!!! @_gear_geek_

[FullControlXYZ @FullControlXYZ]

FullControl python is now available https://t.co/LI9WUSwmXX

Check out the READMEs on the main github page and the 'docs' subdirectory

Hope you find it useful!

There's a cool demo model for printing wing nuts and bolts

Took <2 mins to print an M8 wing nut ⏱

@FullControlXYZ Fantastic achievement 👏👏👏, congratulations 🎉🎉🎉

[Bruce Guest @slonold42]

@FullControlXYZ @BartSpronck @FinnCatling @AleGiudici92 @jasonsau @segers_patrick @_gear_geek_ Sticking to 40 mm height for now while getting a handle on behaviour and printability. Much grist for the nonlinear elastic response mill. So happy with @FullControlXYZ approach, design change to #arterymodel gcode on the printer in less than a minute!!

[Bruce Guest @slonold42]

@FullControlXYZ First #FullControl #artery model is underway! Hopefully, like mighty oak containing acorns, with a 'few' iterations (rapid thanks to #FullControl parametric direct to gcode generation) & a few 100 more mm, we will have #physiologic #pwv #aorta #phantoms by June🤞

[Bruce Guest @slonold42]

@_gear_geek_ Indeed there is, see https://t.co/F807aNEN3I and https://t.co/f1VZcDDOvR Nonplanar printing is required to maintain desired wall shape (mechanical properties) for non vertical long axis orientations and Delta style for length - 0.5m - 2m. Filament is X60 polyurethane...

[Bruce Guest @slonold42]

@_gear_geek_ Very nice!!

[Bruce Guest @slonold42]

@_gear_geek_ What you have accomplished so far is impressive, the future developments will be even more so!

[Bruce Guest @slonold42]

@_gear_geek_ Printing with high-temp (200 C heat deflection) resin is trickier🥵but this morning's batch looks promising! If workable will test flow distribution with the mister, hopefully today🤞

[Bruce Guest @slonold42]

@_gear_geek_ First attempt to print in resin, seems to work!. Holes are 1mm dia. A little more practice and should be perfect! Also have model ready to go for duct without guide vanes. Should be able to test flow distribution in a couple of weeks, will let you know.

[Bruce Guest @slonold42]

@_gear_geek_ Nice summary of the current #opensource (ish) 5 & 6 DoF printing situation🙏 Exciting to see ongoing exploration and development!! Gcode generation and motion control seems to be the hard part. @FullControlXYZ

[Bruce Guest @slonold42]

@GugenTheIdea @_gear_geek_ Fantastic to see the #HEXAprinter making progress. A nonplanar delta style printer combined with the #parametric @FullControlXYZ tool will be a big advancement for #arterialmodels and #pulsewave dynamics #cardiovascular research!! Good luck with the contest🤞

[Bruce Guest @slonold42]

@_gear_geek_ @marbocub I think so, if the opening is too large, the pressure in the header (plenum) may not become high enough to drive air around to the far side. So a very narrow slit or perhaps a ring of small holes. Is it possible to make your air nozzle a separate piece to easily experiment?

[Bruce Guest @slonold42]

@_gear_geek_ @marbocub Flow seems very evenly distributed until very end when the pressure is low.
