"Analogue 3d printer?" Topic

Anyone, no? Analogue 3d printer.

Anyone, no? Analogue 3d printer.

You can get analogue versions of most digital things, why not a 3d printer?

Maybe it missed the analogue hay day, but you could still make one.

You could press records for data.

I'm sure a crowd fund would be successful.

I have one.

What has been will be again, what has been done will be done again; there is nothing new under the sun.

Not to quibble, but you can get analog versions of many digital things because the analog came first, and we mostly abandoned it for digital because that was cheaper better faster. 3D printers as most people know them, are made possible by digital controls.

What you got at that link there is arguably a 3D printer. Some might say it only prints single-wall, radially symmetrical objects, but there are plenty of shapes that are going to give you a lot of trouble on an FDM or SLM printer, so it's just a question of different limits.

But there are automated lathes and all kinds of other machines that make things without human operation. So we need to talk about when they crossover and can be called 3D printers. Well, someone needs to talk about that, but I'm not that interested.

But was there an analogue printer before digital ones? (Haven't watched the YouTube yet, if that's it?).

It seems like 3d printers only came about using digital bits.

However they had wax printers for architecture for a while, so maybe they were analogue?

Digital not always better.

Laser disc is meant to be better than DVD/blue ray.

It's only the more modern materials/manufacturing, smaller size and more space that makes them any better. All things that could easily be used to make laserdisc even better.

The main plus of laserdisc that I see is that scratches are simply read over and don't pause things, and it's easier for the disc to be read.

The only real appeal of digital is compression, otherwise they can share technology, as far as discs.

It's on my list, just the players are so expensive.

Yup that why we have digital 3D printers, the analouge one is DIRE 2mm nozzle, not going to do my 1/144 scale stuff EVER. Seems like no decent materials available.

A hand powered lathe would be of far more use. True FARTISTRY, art without thought or reason and of no recognisable value. Proaqbly an utter farce anyway as the chains and sprockets will be made on digital systems anyway.

Laser disc technology was expensive both for producing the discs and for the readers. It was more reliable than some recording/repro methodologies of its time but was very soon out-done on all fronts by digital technologies. It is not 'easier to read' than digital and requires very precise positioning of the read head, mature digital storage technology is considerably more forgiving.

Laser disc still needs digital motors and digital control systems, analogue systems are simply too slow.

I tend to agree with some of your comments on 3D printing but you really should be careful in dissing other digital technologies as you clearly have limited understanding of how prevalent they are today and how useful.

Even my calipers I use for measuring real items are digital, I am old enough to remember the horrors of Vernier Calipers the analogue version of digital calipers and the Horrors of slide rules is best forgotten.

Oh no! You have mentioned 'slide rules'. I have to lie down… take deep breaths…

If a DVD gets a decent scratch, you have a problem.

Laserdisc, from my understanding, just glides right over such things, whereas DVDs can get jammed up.

They would be able to make a very good laserdisc today. With less scratching, less disc rot, probably at a more convenient DVD size also.

Perhaps, really, it's the player.

Adapt a burner, or just get manufactured DVDs with laserdisc data.

Then adapt a DVD player to read the mini laserdiscs.

Possibly blue ray would be even better.

Could be the next step in discs.

Fast forward through anoying warnings, yay.
