It's easy once you get the hang of it. There are many basic 3D modeling programs available, some are easier to use than others; but they all reach the same goal: to create a 3D object. Once the object is made, you can export it to other supported file formats. Warning: after your first couple of objects, it does become addicting.  zozo-mag |

Modeling 3D for prototyping need good tools.
For Vegan Spacer, I used 3DS Max which is definitly not the best software for this, a good one but not the best.
I want to try Rhino and/or Catia : powerfull tools for NURBS editing.
It´s like using illustrator with x, y and z axis.
Bollean toils are strong and give proper meshes.
I will 3d print the Vegan Spacers to see what´s the final result.
A new company opened last year close to my workshop :
they have 3D printers for rent and also to offer 3d print services with or without 3D assistance.
Will post final results once those 3D meshes done.

I just found the new power tools for Catia : sketching 2D with 3D application. You draw in 3D, the you use it as a sketch layer or you can turn it in 3D meshe : But Catia is first a very strong design software to creat design objects and prepare them for industry editing. And it's a french creation... |

This sh*t blows my mind! I saw a video of a guy who made a complete ball bearing for a functional peddle bike (SLS...?)
Very intrigued where this tec goes and how it affects the world

A new resin printer on KickStarter today for $100.
The downside, may not ship till July 2014. Not sure if I am hip with the home-built galvanometers, but is quite the interesting way to control them, along with the Z-axis floating method.

Wow. It looks like it has a ways to go before being user ready, but just seeing any bare bones system like this at a $100 price tag is amazing.

In 20 years people won't be buying plastic products anymore, they will be buying 3D CAD files to print on their home 3D printer.

Or at least some of the folks who will have actual use for them, such as in the toy industry, movie industry, museum props and display specimen artifacts ***, practical medicine (prosthetic and dentures), artisans and craftspeople, and some businesses in the local home-decor/hardware industries, to name a few. Perhaps it might even equate to the same value as plastic products bought over the counter nowadays, except a tad more expensive for the setup, location, materials, and the cost of human labor to run such machines. ***museum display FAUX specimens, as in Exact REPLICAS of the true specimen; to safe-guard the actual specimens from theft. Example: a thief breaks into a museum and steals a dinosaur tooth, thinking he
got away with a high-value specimen, instead he got away with an authentic
specially marked fake replica that can be traced and land the thief in jail.zozo-mag In 20 years people won't be buying plastic products anymore, they will be buying 3D CAD files to print on their home 3D printer. |

noob question to those who printed out in 3d...i just made my 3d solid and i want to print it.....how do i know its in the right scale and do i need to create an account??? which compnay offers the most economical way of 3d printing services??? thanks guys....

You need to open the file up in your 3D program and use a measuring tool of some type. Every program should have some kind of tool that can measure the dimensions. An exported .stl model will have the same dimensions as the native model.
Probably the cheapest way to print would be to use Shapeways.com "white strong and flexible" material which is polyamide. You can choose to have it rough or polished. Choosing the polished option will make it feel smooth but you do lose just a little bit of detail.

I've tried using netfab and meshlab, and I still couldn't
figure out how to get the proper model requirements (wall thickness, scale, etc)
for my objects.
But that's okay, I'm in no hurry. One of these days I'll have to seriously
sit down and experiment with netfab to get it done right.
I'm also gonna try the Autodesk 123D Make program.
I'd wish there were an easier way, but I'll never learn the right way
if I don't take the challenges of these programs.
CG modeling is different because it's mostly for animation and
still-image graphics.
3D modeling for printing out solid physical objects is a little
more complicated at first, but should become easier with more practice.

It will fix most basic problems, but you have to follow the steps in order, otherwise it won't solidify the model, it will only "look" at your model and maybe tell you what's wrong with it but not do anything about it. Maybe tomorrow at work I'll go through the steps and I'll try and find time to list them here. |

I honestly want to try this out ever since I've heard of it. I've successfully turned some plastic models into brass using the lost wax casting process. The ABS plastic also burns out right and since these can print this kind of plastic it would really help me out in a lot of projects. The only problem with these 3D printers for me is I am an extreme noob when it comes to software.

Take your time. I really appreciate your help, and I'm sure others appreciate it as well. I'll take notes and print that info out on paper so I can follow along as I try a new object in netfab. zozo-mag I've tried using netfab and meshlab, and I still couldn't figure out how to get the proper model requirements (wall thickness, scale, etc) for my objects.

Learning 3D software can have a bit of a curve. My personal favorite free 3D program is Sketchup, especially if you are new. The tutorials are excellent and it's fairly intuitive. Other options are Blender and 123D which are both fine, but not as easy as Sketchup in my opinion, and they don't have the ready made tutorials that Sketchup does.

It will be sometime before I buy a 3d printer since these are still new and I'm certain there will be better and cheaper printers that will come out. I'm not in a real hurry to buy one but it would be wise to learn the software and have it printed elsewhere in the meantime. I'm actually surprised that these printers are now being sold in my country and also offering printing services. I hope 3d printing goes mainstream cause it could lead to all sorts of innovations and creativity. |
