Re: Material Strength

@TomBurgmann: My observation is that most 3D printers use material that is too flimsy to handle much stress. The thought of printing out a gear or even replacement cap seems like a high investment for an unsubstantial return on effort.

I believe there are different types of 3D printers, including "sintering" versions about which I know almost nothing. From my experiances so far (a few small test prints) using the plastic thread I would agree that prints created using this material aren't strong enough to take any serious loading.

Howerver, they would be more than stong enough for  prototype enclosure, or to create my "scroll gears" -- just to demo the way the gears work -- not to carry any load.

I will report further when I've had more practice :-)

Please comment on your observations about this aspect of 3d printing.  Cheers!

@Olaf: ...The original manufacturer wants 20 dollars for this little piece of plastic.

Did you see my column from yesterday about some new 3D design software called DesignSpark Mechanical? Once someone (like me) learns to use this, you could whip up the design for a part like that in a couple of minutes -- I think we've reache the turning point where 3D printers are going to change the world...

@daleste: This is really cool stuff!

      It really is, isn't it

Please keep reporting your progress.

      I will certainly do so

It makes the rest of us so envious.

      I'm sorry (but grinning also :-)

Maybe you could print me a new screw cap for the rinse aid reservoir of our dishwasher. It is broken. The original manufacturer wants 20 dollars for this little piece of plastic. I think they are crazy. ;-)

Sure thing!. It may take me a bit to get the CAD file done. First I have to get to the opener, which is 15' above the floor, then take out the stripped gear... Don't use up all your ABS supply too quickly!

@Rich: You taking orders?

Since it's you Rich, if you send me the 3D file I'll see what I can do :-)

You taking orders? My garage door opener jammed stripped a gear. I could use a replacement.

You don't honestly think I would submit my own for public scrutiny do you?

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
