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."

3D printing

[ledow]

I can't speak from experience but the things keeping me OFF 3D printers at the moment are:

- Too much faffing about to build the things (or too much cost to acquire them pre-built).
- Too much faffing about having to calibrate, adjust, tinker and play with them to get good results.
- Too fragile (i.e. you can't throw them about, take them to a friend's house).
- Too reliant on a small set of manufacturers (for the source materials, software, etc.)
- Still no established 3D printing "standard" in an OS. Sure, there are lots of "almost-standards" but I'd rather avoid another mess of things not being compatible - non-compatible printers just puts us back into the range of "I have to buy the same printer/manufacturer again because I don't want to change all my setup / software / source material" but in an era where it's too expensive to perform the current "Sod it, throw it away, buy the cheapest one again, suffer the time lost" scenario we have with 2D printers.
- 3D models are just that much harder to make and print reliably. The two examples of software you point out? Both licensed only for home use. Google Sketchup is the same. As soon as you say 3D, you have to pay for software (and driver integration, or learning-curve) so we've jumped back 20 years again). Then every home-built printer will have different tolerances and results.

3D printing needs to become a consumer-level tech. It's not. It's still up there with all the existing methods of plastics / wood / metal construction from a computer model. In the range of a trained person with expensive hardware in, say, a school for a specialised project. But not for the amateur home user unless they are prepared to spend as much time tinkering with the system as getting results out of it.

To be honest, I will look at 3D printing seriously, even for personal hobbyist use, when someone like HP or Epson or a big name (hell, doesn't even need to be a printer manufacturer, Dyson, Samsung, whoever) produce a small black box. From that I put in up-to-but-no-more-than four materials / colours / dyes in a standardised package. I get a free bit of software with a few thousand models and - critically - import of any 3D model and/or conformity to a standardised 3D printing protocol so I can use other software. And it just works. Every time. I print, it comes out exactly as it is on the screen. WYSIWYG 3D printing. I don't even mind if it costs as much as a really decent 2D printer with more expensive consumables. But the hurdle to jump is the simplicity, repeatability, the hands-off method of printing, the automatic calibration and error detection (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?), the single-black-box that is available complete, without assembly, from Amazon, tested and ready to go.

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.

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.

Re:How many unhatched chickens? So many.

[gl4ss]

I got a Replicator dual(was 2400 euros or something shipped). total beta product as far as dual goes(using 2 materials). works ok after many community tweaks. made some parts for friends, keychains etc.

I've since bought two repraps, and now I have the opinion that spending over 1000 bucks on a fdm 3d printer is just pure madness, unless you go and spend 8000 and get a mojo(expensive prints but easy peacy to do the prints).

why put so much money into this? because it's fun. it mixes electronics, mechanics, motors, robotics... so the printers themselves are a hobby in itself too and you get something tangible out of it for your efforts. it's much less noisy and approachable than cnc routing etc similar and much cheaper too.

summa summarum.. unless you're already running a prototyping biz you can't just make money easily by just printing. if you need 3d prints for some other job(design or whatever) then you can save a lot of money and time by running your own 3d printer though..

buying your first printer and being all "oh I'm gonna make so much money from this" just doesn't quite work out. you can use it to complement some other business you have, but it's hard to compete on the market for just making the prints. however if you're doing freelance parts designs or such stuff then you pretty much have to have one now.

3D printers cannot be consumer hardware

[janoc]

I think you have unrealistic expectations fuelled by a lot of the hype around the printers (and the companies selling them).

Setting the poor quality and the need to constantly tinker with the calibration, belt tensions, levelling and what not aside, 3D printer is not a consumer device, even if it was plug & play today.

It is a machine tool and a pretty complex at that. Programming and using a 3D printer is comparable to a CNC router, which is a specialized skill that usually requires some extensive training. Sure, it is not rocket science neither, but expecting this to work as a printer in Windows (push a button and paper comes out with your document) is simply unrealistic.

Demanding things like "standardized 3D printer protocol" (hello g-code ...) or companies like HP or Epson to produce 3D printers is off the mark - why should they? They don't make other machine tools neither, the only thing a 3D printer has in common with a regular printer is the word "printer" ... These are all red herrings - those things are pretty much irrelevant. Without the engineering knowledge needed to build the part you won't be able to make a useful component beyond downloading and printing stuff someone else made. However, then you can order the parts cheaper and simpler from Shapeways or a similar place too.

The same holds for design of the parts - people complaining about the complexity of the CAD tools are way off the mark here. The tools have to be complex in order to be actually useful, otherwise designing precise parts would be impossible. Unfortunately, a lot of people think that CAD is like Photoshop or something - it is not. If you cannot construct a piece using a ruler & compass on paper, you probably shouldn't be using CAD neither.
