No it is definatley a design fault of their planning.
You are the maker of the object you control the process if you make a design error it is not the object that has caused it as the object is still nonexistent.
I quote from their campaign
"As 3D printing becomes more ubiquitous in our lives and work, the demand for superior print quality is racing ahead of what ordinary 3D printers can provide. Smoother surface quality, higher stability, and higher print efficiency have become basic expectations.
Other common complaints include:
Hours of debugging for marginal improvements
Faults during printing like print heads jamming and layer shifting
Complex workflow and inaccessible operating software
After more than 3 years of development and testing, we believe that our printer has solved all the above problems. We hope that through our efforts, IVI will become a milestone for desktop printers.
" We see crowdfunding as the perfect chance to verify our product and idea. With early support we can not only receive pre-orders but also precious feedback regarding product improvement.
It is our hope that every backer has the chance to engage with us directly and offer suggestions, ideas, and criticism. That’s why we have set up a Facebook group. We have been, and we will continue, answering all questions while remaining completely transparent throughout and after the entire campaign. Together we are a team, and our combined effort will nurture IVI towards its full potential."
Of course, nothing in life is free. Production, manufacturing, and supply all require significant investment. Which your pledges will cover. "
As to the attack on my qualifications “Monday Morning Quarterback” i will just say Absence of evidence is proof of nothing as to the complexity, I would say a five axis positioning system with measuring accuracy of 0.005mm , mechanical as well as control, is no small feat for 20 years ago, and was done in 6 months from start of design to actual production implementation A project of only six machines but at similar cost to this project, Noted not self financed, but was done within budget and on time for a major Tyre supplier. And yes in-terms of their projects this was a small project.
I have also self financed and built a Ravin 500 Aircraft, in 3 and half years spending only Saturdays and Sundays on it as a hobby and performed the test flight in the aircraft.
I have enough confidence in my experience, and to make blunt statements I have a 40 year track record I am electrical engineer B Eng as well as Master in Eng specializing in Project management.
This project failed out of the starting line, no dispute from any one, they have admitted as such. They are trying to recover, but in my view has gone wrong, I am providing my critique, as requested by the campaign (see their quote)
They have missed TTM Time To Market machines with similar spec’s can now already be obtained at similar price levels.
At this stage I am predicting their funding has become constrained, proved by request for shipping self assembly units, Carrying a design and development team for 16 months past your budgeted cost must hurt, not adding the extra cost of multiple mold redesigns and different suppliers.
Are any of the backers willing to provide extra funding if they would asked, as I believe they can barley make target, would you be willing to double that you have put in.
If they provide me with detail design plans, test schedules and realistic project plan, I would consider it seriously, In the end it is just $300 more. And yes I funded the project open eyed not expecting any return, but if providing my critique can have a material effect , it only cost me the time to type these messages that I estimate at $300 by now.
