Excellent Radio Show, Jon, Todd, and Brian. Thanks for your efforts and thanks for a lively chat from our audience today!

Iron

Thank you Brian and Todd

Thank you, Todd, Jon and Brian.

 

Iron

Thanks all for listening and for the great questions/comments. Best of luck with your 3D printing (ad)ventures.

Blogger

I would like to thank Jon and Todd once again for taking the time to answer your chat questions. And thanks for listening!

Prassa, yes. Inj. Molding fully melts and fills the mold under pressure...so fully dense. With FDM, you'll have some "pores" if you will. Don't know exactly what the density is.

Blogger

Jonathanlee, well put. Lots of different segments to this industry, and I forcast lots of segemenation (e.g.,machines ofr specific apps/industries).

Blogger

Tood is there a variation in the densisty of an inj molded part and one built on a 3D printer?

Iron

Prassa, a 2" solid cube would weigh about 5oz, if my math is right. If you had your hollow cube with 0.010" walls, about 0.18 ounces.

Blogger

The future of 3D Printing will include systems that are much easier to use, this includes support removal issues and are much faster.  Price will continue to decline.  All this at the low end.  There is another growing segment for end use part printing, here materials, part cost, repeatability, speed repeatability are key.

thanks Todd will get back to you thru' the website

Iron

Prassa, from my tests, straight and true. No bowing, leaning, bending on a verical side wall.

Blogger

How perpendicular would the edges be?

and the approx cost of material for the 2"cube , weight as well

Iron

resourcer, open source communities are the big variable. The masses may come up with some exciting advancements. But to date, it has been tweaks on already existing technologies/platforms. Hopefully, something(s) amazing spring up from the rising interest in 3D pritning.

Blogger

Todd, I've heard you talk before about how, counterintuitively, technology users expect more ease of use with lower-priced machines. I think that fact supports what you say about simple operation in the future.

Iron

resourcer, expected for the future is a fun one to tackle. Lots of bold cliams (home-based mfg revolution), but only time will tell if it happens near term. For the 3D printing segemnet, I do expect more systems with simple/transparent operation, some new technologies to arise and more materials. All while prices decline.

Blogger

Prassa The build time would be around 1 hour to complete the 2" cube.  If you would like I can send you a completed build per your request allowing you to measure the part.

Only so much that can be covered in 30 minutes...

I didn't hear "what's expected in the future"... maybe didn't get to that...?

At Stratasys our printers require that a software vendor produces a .stl file.  We print from this file format.

what would be the build time, quality and precision of a box 2"x2"X2" having a wall thickness 0.010"

Iron

For most printers, STL files work weil.

Is a special CAD software required to disign the model for the 3D printer?

 

Iron

Check out TinkerCad if you want to see what kids are doing with 3D printing!

Grade schools are teaching simplified CAD design, maybe adding simple shapes together to create a unique part or following a scriped design process to build a simple part.  The idea is to quickly show the student a final part.

Thanks for the show. Will go to Statysys website for additional info. and folllow up w/some questions via e-mail or call.

Iron

What's making the market accessible are the many sub-$1000 and sub-$500 3D printers.  Just like ink-jet printers, quality of sub-$500 3D printers will get better in a matter of months until manufacturers are giving them away and charging for the media.

hwang, what gets me most excited is that it is used as a tool to get students excited about science/technology. Fold it into a curriculum where a 3D output makes sense, and watch the fascination on their faces.

Blogger

Of the 3D printing technologies, which one produces parts which are most similar to injection molded plastic?

Iron

Listeners, I forgot to second Jon's statement of quiet operations. I sat 18" from an operationg Mojo and it blended into the ambient noise. 

Blogger

dodger12 The trial pricing includes the use of materials and the Mojo printer, as such is not included in the purchase price.

What do grade schools use the 3D printer for?

 

Iron

kadydid, my pleasure.

Blogger

Todd, I agree with your statements.  Part quality, build speed, surface features and part details are key benifits to Mojo printers.

Ok, that helps, thanks

 

Iron

kadydid, another way to consider that is how small of a feature can be produced. I believe that to be 0.020" for a wall, boss or rib.

Blogger

If I decide to buy after the trial will the trial cost be added to the purchase price?

Iron

kadydid, XY resolution doesn't apply. This is a vector based process.

Blogger

I hope you enjoyed the chat portion of the program. PLease continue to enter your questions and todd and Jon will get to them.

 

Jon, any additional comments to mine re: Mojo vs. Makerbot?

Blogger

I understand that the layers are .007".  What is the X-Y resolution?

 

Iron

gc3d, unless you see them run side by side, it is hard to put into words. Both have the same core process. Where it gets different is with a heated chamber (better part quality) and the precision of the build.

Blogger

svarughe, depends on the application. Supported surfaces don't need sanded to remove supports (they dissolve away). For sid walls and top surfaces, sanding may be needed to have the smoothness required.

Blogger

Hi Nestor - If you are having audio issues, can you please refresh your browser using F5 or try a different browser?

Iron

Can Mojo do multi colored printing?

Iron

Does it need sanding after getting the part out of the printer?

Iron

What advantage does the MoJo have over the MAkerBot?

Iron

Mark N., this isn't that kind of printing. So you really wouldn't be looking to print on an existing part/part surfce.

Blogger

jakeller, no. Mojo has one material. An opaque, ivory colored ABS.

Blogger

Can you produce clear parts with the mojo?

 

Iron

I do not listen anything about this "3D Printing Accessibility Grows Marktes"... could you please help me with that? thanks
