Pete, I added more above.

Regarding candy, I think this is going to be HUGE. 3DSystems, the largest 3D printer manufacturer on the planet, just announced a commercially viable printer will be for sale this year. You can actually buy 3D printed candy (13 pcs for $36!!!) on their site right now.

I swear I read at least one story a day about 3D printing be it on Wired, Mashable, gizmodo or some other article and they all suggest to me that this is the future.

So, what now?

How can I make money doing 3D printing?

When should I buy a 3D printer?

Which one do I buy?

These are just the easy questions, the big one is what do I use it for and what material do i use, how fast will my printer be obsolete by a faster cheaper one?

Anyone here got a 3D printer and making money?

I really would like to get involved but do not know how or if it's worth the cost.

I've spent the last 5 years working in 3D printing, so I'll answer these questions as I have time to the best of my knowledge. If anyone else has questions, ask below and I or someone else with knowledge will answer.

Q: How can I make money doing 3D printing?
A: This one's a biggie, and one I hear a lot...Sell modeling services, sell 3D printed products, or sell 3D printable models (sorted in order of most -> least likely to make money). There are literally dozens of other ways to make money in the field, but for most of us on the forum that know how to 3D model, this is going to be a huge advantage.

Q: When should I buy a 3D printer?
A: Don't be in a rush. At this point, Spring 2014, the printers that have nice output are too expensive for a small business just trying to make a buck, and the ones that are less than $2,500 are generally difficult to maintain and have a rough surface finish. My recommendation is to use a service bureau like Shapeways, i.materialise, or MakeXYZ.

Q: Which one do I buy?
A: If want a printer for general use, look for a Rep-Rap style printer like Ultimaker. These printers are relatively cheap, use cheap material and are safe enough to use in your home or garage. If you find a niche market, then look for a printer that can accommodate your needs. There are many kinds of specialty printers, i.e. full color (good for architectural models), resin (good for high detail prototyping), ceramics, wax (for casting metal prints), and more.

Q: Anyone here got a 3D printer and making money?
*A: I have a Solidoodle 3D printer, and am making money, but not directly from the printer. The printer has a 6" cube printing capacity, uses ~$30 spools of filament I buy online, and costs $700 (I got lucky and won it in a contest).

I make most of my money in design services for people that want to 3D print something, but don't have the modeling skills and 3D printing knowledge. See, modeling for 3D printing is different than just making a model to render - you have to take into account material properties, minimum details, wall thickness, and the model has to be "Solid" or it won't print properly. There's more too, but that's a good start.

The printer is nice for prototyping because when I'm designing a product for a client, I don't have to wait 2 weeks to get a model back from a print service. In an hour or 6 (depending on the size of the model), I have a prototype ready to test and re-design.

I also make money selling finished 3D printed products online. My big seller is a line of medical jewelry, printed in Sterling Silver or 14K Gold by a print service. I got lucky and found a niche that wasn't being filled by anyone else, and the 3D printed products fill it perfectly.

The hard part about all this is marketing - getting the my services and products in front of the right people...meaning you may be the best 3D printing designer, you aren't going to make a penny if the right people can't find you. I have a website that I get some business from, but so far 3D printing work alone isn't enough to support me.

Because of my website and other articles I've posted online, I have been approached to write a book on 3D printing with Sketchup and asked to speak at a business conference...so my marketing is starting to work. The whole 3D printing field is like the wild west right now, and savvy people WILL strike gold.*

(I'll edit and add to this first post as more questions come in)

Let's start a new thread, I'll pitch in over there. I'm making a little money at it.

Oh yeah, I can see multiple shadows now.

....and I'm not going. Pre-existing scheduling conflict that I didn't think to check before signing up.

Looking good, Dave

Any suggestions from the rendering gurus on how to give the stools the appearance of weight. It looks like they are floating on the carpet when they should be sunken in. Maybe I could make a mesh and depressions under the feet with sandbox tools? Any other suggestions?

I'm no rendering guru, but I think adding a light directly above the stools above will add some shadows under the stool to help 'ground' it. Right now it appears like you only have one light in the scene.

I painted the light bulbs with Luminous material and created a point light just below the light bulb. I get the glow of the luminous material and I get the light pattern I am looking for.

Nice solution. Fire looks great too!

@jawsnaz said:

I have also tried that. When I scale the point light down small enough and insert it into the luminous material the luminous material blocks the point light from escaping and does not create shadows.

It seems like the point light treats the luminous material as a solid object.

Ok, what if you paint the inside of the luminous material with a transparent material? I don't have LumenRT 4, or I'd try it myself...

What if you put the point light inside the luminous material, so you get shadows and the frosted light bulb effect?

Woot! I'm coming Monday morning.

My favorites are:

• Sketchup to STL
• Solid Inspector
• Cleanup

Good little tutorial, Carsten. Running the cleanup plugin at the start will make it go even faster.

This reminds me of Michelle Morelan's work: http://schematiclife.blogspot.com/

She uses hand sketches with pencil and marker, and sometimes a Sketchup model as an underlay. 23 min tutorial: http://vimeo.com/groups/2Danimation/videos/13479536

Oli, those were actually parts for a 3D printer..gotta love the 3D printed gun hype http://www.3ders.org/articles/20131025-3d-printer-gun-parts-found-in-manchester-raid-may-be-parts-for-a-printer.html

The engineering that went into making that is impressive, but I shudder at the cost. DMLS is not cheap - I bet that gun cost as much as a luxury car.

...and yeah, anyone else notice that both this and the first 3D printed plastic 'gun' were made in Texas?

Look to see if you have a nested group(s) and or component(s), as Solid Inspector will not alert you to those.

I did the lessons for a while. I really liked the system...never did any real programming with it though.
