More rubbish from whiskey I see.
He sure knows a lot about stuff he has never tried.

I think this obsession with resolution must be because people are
wanting to print tiny or high resolution items with the wrong tool.

Exactly and they also think 3D printing is more advanced than it acutauly is.

Most people expexct far more from a 3D printer than it can do.
The cheap 3D printers that you can buy are fine if you don't expect much from them.


It would be like trying to fix a watch with a hammer.

Like using a screwdriver as a chisel which can be done, a coupe of students achieved that here, but that doesn't make it the right tool for the job.


However, if you are printing 'appropriately sized' things and that
actually suit the *actual* finish needs of the job, many of even the
cheaper printers (these days) will do a perfectly good job.

dependign what yuo mean by a perfectly good job.
Here we try to educate studetns to use the right tool for the right job.
This is why when the college wanted to make bones using a 3D printer they spent 1/4 million rather than a £99 one from ebay.

It's like basics baked beans versus Heinz, yes basics taste
'different', primarily because they often contain less sugar and salt
but they are still just haricot beans in a sauce. ;-)

But I can taste the differnce and luckily I actually prefer the home brand cheaper ones because they taste less strong or tomotery.
This is why you have tatsers because some can tell the diffence.

Like cars most 3D printers will be OK for most home users but ther are some people that need a large car such as a 7 seater or a sports car.


After actually / regularly using 3D printers (and my point) you
'learn' that that is equally acceptable for the function ... not
everything we use *needs* to have a mirror finish or be 'perfect' to
perform it's goals admirably.

Of course not but the day when you decide yuo want a mirro finish is that before you buy the printer or a month after using it.

It's like Morrisons now selling 'wonkey vegetables' ... aren't they
just 'vegetables'?

No idea in theory they should be cheaper.


Nothing I've ever printed has failed to be suitable for the job in
hand.

Well it shouldn't be if you know what you are doing.

No one has ever questioned the finish or the detail (often the
opposite) and most have been fascinated to see something being
designed on a PC and to have that object in their hands a while later.

So which 3D printer do you have.


*That* is more the point of them from my POV and the whole point of
the RepRap / Maker type movement, not the manufacture of perfect works
of engineering art (even though they often can). ;-)

We are looking for someone to look after the 3D printers and assocaited stuff.
