"I have attempted to explain.."
Garbage! You have attempted only to browbeat and discredit everyone who makes a positive statement, and to fabricate ludicrous rubbish about the company, the process and the potential. You "don't have the time" to read facts, although you have plenty of time to type unadulterated rat shit about what you THINK - most of which is quite incorrect, and some of which verges on lunacy.
In fact, your posts over the last couple of days have been so ridiculous that you have proved yourself completely ignorant of both 3DM and their potential markets. "Engineer"? Don't make me laugh! Shot in both feet, IMO. A self-administered credibility-ectomy.
And as you so rightly say, it's my money, and my decision. So why are you hellbent on persuading me and everyone else to sell the stock? Why post arrant nonsense about a company and a technology that clearly confuses you and which you cannot understand? I have already banked enough profits from TDM, on three separate occasions, to cover the cost of my present holding. If the 3DM story changes - and if the alpha machine does not deliver commercial viability, the story WILL change - then I will sell. Until it does, no amount of your ranting, deliberate misinformation and downright lies will frighten me into doing so.
