do you use a Envisiontec bioprinter to make that? what is the smallest diameter vessel you have printed so far? ...from my point of view the most difficult part is to find the way to print precapillary vessels and arrange a venous drainage... also there is a huge technical chalenge for surgeons to connect this flabby construct to existing tubings without clodging and ruptures.by Andrius - Tissue Engineering
"working blood vessels" ...... could you elaborate more on this?? may be I've missed something on PubMed? txby Andrius - Tissue Engineering
silicone is supposed to transfer heat and fix glass to Prusa heatbed which bends on heating and is way smaller than built bed of BFB3000 so I have no option to use buildog clips double sided adhesive tape is no option too - it will deteriorate on heatingby Andrius - Reprappers
so you fix glass with buldog clips? Have you tried to attach with silicon heat paste?by Andrius - Reprappers
to:brnrd thanks for glass idea what glass you use ordinary one or forged? how your prints stick to glass? do you coat it with some type of film or sand blasted it?by Andrius - Reprappers
bulldog clips will not help, since print head will hit them as RepRaps building platform is way smaller than BFB3000 I tried to loosen bolts and make holes bigger to allow expansion, but not much of improvement May be the heatbed is bending by itself without fixation ....ex. because of different expansion of base material and cooper lining??? I'll try... On the other hand Reprapresource design isby Andrius - Reprappers
"the lawyers insist that the outside company reduces our chances for lawsuits. " you mean that you have a GMP compliant contractor? How much do they charge per built or weight (100gr)? what molecular weiht PCL they use to make your scaffolds? Any additives like HA and TCP added?by Andrius - Tissue Engineering
Hi there I try to use a heattbed from Pruso on the BFB3000. I bolted it to built base and ..... heatbed bends when heated (80 degC). I know it's physics ..... how do you solve this??by Andrius - Reprappers
hi nophead thank you for the input it seems that we are talking about similar materials but surely not same Mine is from Sigma Aldrich #440752 - it's not springy or plastic in any way although it melts at 60 deg.Cby Andrius - Tissue Engineering
Hi I see a lot of discussion here about printing tissues organs etc.... Most discussed material is PCL (aka polycaprolactone, CAPA, polymporph). To my knowledge it is hard wax (at RT) like material so I really doubt if anybody of forum participants have got a reel of pure PCL filament and printed. If I'm wrong please share your experience here. Other popular choices in tissue engineeringby Andrius - Tissue Engineering
