3D Printing: Have You Taken the Plunge Yet? Planning To?
First time accepted submitter mandark1967 (630856) writes "With recent advances in working with different filaments (Wood filament, Nylon, etc) and price drops seen lately, I'm curious to know how many of you have decided to take the plung and get into 3D Printing. There are several kits available now or even assembled units that are in the same cost range as a 'gamer' video card (DaVinci 1.0 for $499, Printrbot Simple 2014 — $399, 3d Stuffmaker — $499).
I'm wondering if any of you have purchased a 3D printer and how you like it so far. I've been in the computer field since the 80's but never did CAD work before so I was very hesitant to take the plunge, fearing the steep learning curve of mastering programs like Blender or AutoCAD. What I found, however, was programs like TinkerCAD and 123Design made it very easy to learn basic CAD so I decided to pick up a 3D Printer last week. After a week or so of design work and printing out many items, I think I've picked up a few skills and I can actually see myself making a little money on the side creating and selling items. I don't think I'd trade my current job for one designing and printing items, but it is nice to have a little income on the side if I choose to do that."

You're really misinformed. You don't NEED to pay a single CENT for software that creates 3D models. Blender is fully compatible with 3D printing techniques, and even has integration with some 3D printing services (like Shapeways) these days. And guess what - Blender's completely FREE. I've printed tons of stuff on my own already just using stuff I made in Blender alone.
Quit spreading uninformed FUD, bro.
3D printing isn't ready for hobbyist level yet, it's still more for early adapters but several of your concerns have been fixed in the past few years.
- The more you're willing to spend on the printer the better quality results you'll get from the printer with less tinkering.
- Windows 8 does have a standard 3D printer driver. Not every 3D printer may use it but you have to admit that there will be some standardization on drivers MS puts out. You'll still need an authoring program, but that's not different then needing a writing program to create a 2D document.
Personally I don't see 3D printers really taking off until there's a "killer app" for them. Until there's something that everyone just needs to print and customize. Something like lego mindstorms or artistic iPhone covers or skylanders. Until that happens most 3D printers will be relegated to knick knacks and smart phone cradles.
- Too much faffing about having to calibrate, adjust, tinker and play with them to get good results.
Whether that's too much depends on you, but yes. They do require a fair bit of faffing to get used to them. The first 10 prints *will* fail. Once you learn the machine well enough you can reel things off reasonably quickly. They are not yet plyg and play.
- Too fragile (i.e. you can't throw them about, take them to a friend's house).
3D printers or the parts? They're not too bad. The homebuilt ones tend to be les robust, but many re reasonably solid. There are even some collapsible ones designed for portability.
- Too reliant on a small set of manufacturers (for the source materials, software, etc.)
There's lots of manufacturers of the printers, and besides the designs are mostly open source. If you have something like a broken morot, you can essentially plug in any old stepper as a replacement. Plastic filament likewise has plenty of sources. Also, there are now designs for machines for making filament from pellets. ABS pellets are not going anywhere.
- Still no established 3D printing "standard" in an OS. Sure, there are lots of "almost-standards"
If you are using the open ones, then the standard in the OS is completely established. It's an open chain with standards all the way down.
Models are generally described in STL (one of the stupidest and easiest file formats in existence). Very standard.
You load the STL file and convert it into G-Code, or generate g-code any way you want. G-Code is used for almost all CNC machines and extrusion type 3D printer. Very standard.
You either load the STL onto a micro SD card and stick that in the printer (all standard) or you connect over RS232 over USB. cat will do for sending the file but you could use pronterface ot octoprint if you prefer a nicer interface.
There's no need to have this in the OS, and apart from the FTDI driver, it makes little sense to do so.
- 3D models are just that much harder to make and print reliably.
That's true.
The two examples of software you point out? Both licensed only for home use.
For open software the choices are not that great. There's BRLCAD (which is amazing, but you only get to really make use of the awesomeness if you want to know how well your 3D model holds up under fire), OpenSCAD and for a more arty feel, Blender.
For paid stuff, don't bother with autocad, it's awful. Solidworks is much better.
and driver integration
No such thing: you are under the impression that the software stack is more complex than it is. Without exception the CAD programs can emit STL files. I suppose that's the driver integration, since all 3D printing systems will accept STL files.
why can't we combine with something Kindle-like to detect when the print job is going wrong and have the printer slice off the last layer and start it again?
Wouldn't be very helpful. The printer always prints layers correctly. The problems are things like the model becoming unstuck from the base. Once that's happened it's time to scrape off the remainder and restart from scratch.
Until then, it's nothing better than a hobbyist electronics kit, or someone building a high-end overclocking rig, or one of those RPi racks... the domain of someone who has so much time on their hands that they don't actually need the printer in the first place.
No, not at all. It's like home computers in the early 80s. You need to know what you're doing to use them so they're the domain of people who either love the technology or really, really need to get some computing (or now printing) done.
I fall into the latter category.
