A few weeks ago I pulled the trigger on a FlashForge Creator pro, a few minor early stuff ups, levelling and adhesion uses. 1st print was supplied with the printer, 2nd off thingiverse, 3 a battery cover for an old HP 41 calculator associated printer 82143, a bit rough but highly functional. Pretty happy so far. Agree Fusion 360 is a bit of a risk - they can pull the plug at any time - but not as steep a learning curve as I thought.
Whoah! Watch where that landed we might need it later.

Providing they continue to allow exporting is a few different formats like IGES or the others and local saving risks are minimal. Very worst case might be you have to stump up for a months paid subscription to get your files but the backlash from that sort of change would be epic.

FDM was actually developed and commercially marketed quite a long time ago. The patent expired, after which it became fair game for tinkerers and hobbyists. The same is now happening with SLA, although that one turns out to be a bit harder to crack and there doesn't seem to be a coordinated effort to improve the technology like there was with FDM in the form of Reprap.

FDM is never going to have a finish as good as some of the alternatives, but it's relative simplicity and useful printing materials will probably make it a popular choice for a while to come. It's really amazing what you can do with it, although some people fall into the trap of applying it to every problem whether it's a suitable solution or not. I'm glad the days of people printing endless amounts of useless trinkets seem to be passed and people are more and more using their printers for more useful prints.

What was developed commercially was so far from what we call FDM now as to be a completely different product. Numerous products, all suffering from the "SONY trying to own it" disease, each entirely devised as closed ecosystem. All different idiotic mechanisms to try and make 3DPrinting work like conventional printing where you had to buy your supplies from the printer manufacturer, only this time lock out the cartridge cloners for good.

Shocking that nobody could make it commercially viable with the same "consumable supplies that cost more by weight than gold" business model as inkjet printing.  :-DD  FDM as we know it using off-the-shelf actuators, global-standardized filament sizes and formulas and platform-independent generic controllers was entirely devised by the hobbyist market.

What we really need now is a tertiary product that can directly print molds for metal-casting. I've already done lost PLA at my local Hackspace; while it is theoretically "amateur-able", there really needs to be something more straightforward and single-step to a usable mold, and so things like proper sprue and vent sizing/location can be part of the prep software and safe defaults preprogrammed.

Would be a total game-changer, even if you could only get down to like .4mm layer height, with something the size of a Tornado you could do real, usable machinable castings in a usable framework of time & assache. Many applications could STILL be usable roughcast.  We have small, cheap inductive kilns that can do a couple pints of non-ferrous metals on a benchtop already.

* Calibration long out of date *

see https://www.eevblog.com/forum/metrology/ptb-at-the-maker-faire-in-hannover/msg1267015/#msg1267015

Henrik will do that  :)
We are also this year side by side in the makerfaire Hannover, my Wellenkino Team with Oldies, and the PTB with calibration for DMM

Do they really have the proper fixtures to calibrate a tinkerdwagon? Would be worth the airfare if they did, for sure...  :-DD

Stratasys owned and exploited the patent. They still sell FDM printers today, so it seems to have earned them enough money to keep the technology on board. How about something like the link below for casting? I think that more than one manufacturer is doing something similar.

Some of the Resin based metal castings I have seen done are amazing but I still don't want the suffering of a Resin Printer ;) Investment or Jewelry grade results.

I use the cheap commercial additive printing companies for that kind of thing.

I've even got a finished, shiny, brass piece back from them (I couldn't afford gold, silver or platinum :) ).  That lost wax printing technology is used in the jewellery industry.

People being so willingly locked into cloud type environments is a worrying development.

History rhymes: there was a precursor to the cloud...

Those of us with a long memory remember (remote) timesharing environments, single vendor machines and programming by the priesthood.

A major reason for the rapid rise of the IBM PC ecosystem is that users were able to prise their data out of the hands of the vendors and control it themselves.

There's too much truth in that.

Over here there's decent radio programme, "The Long View", which takes a contemporary issue and compares and contrasts it with a historical analogue. Examples:
  • railway safety in 1830 vs driverless cars
  • Saudi price vs the Pope
  • Facebook revelations vs the Reformation
  • Uber vs London's watermen
  • targeted fake news
  • Brexit vs Elizabethan free trade (Lizzie the first, that is)

Just as a note on the cloud. The competent elite in the IT sector refuse to use it and keep all their files in platform neutral formats. That’s always a sign of things that will come in the future.

I will use the cloud myself but IaaS and open source only because that’s where the cost benefit is. If you lock yourself into an API it’s game over.
