Greetings fellow Shapewaysians / Shapies!

I'm here because I've been drawing pictures all my life and this is now an opportunity to put those marks on paper into physical 3d form! Hurrah!

I'm a native and still resident of a large city to the south and west of the megalopolitan juggernaut that is New York known by the name of Philadelphia. So close but really actually a little too far to go for the casual meet up and brown bag type of shmooze event though I do make it out to "the City" approximately every other weekend and that frequency might increase. The Bronx, albeit, but never mind that...

My background in 3d modeling dates back to the early 90s when I worked for a boutique outfit marketing collections of 3d models distributed on CD ROM. I was the technical issue problem solver and utility program author. Our primary software was Wavefront and as a side note one of the tasks I undertook then was to write programs to manipulate obj files and to develop production processes for taking obj files and converting them to a host of other animation software formats such as 3dStudio and Lightwave and VRML and on and on. So I became passingly familiar with a whole lot of different modelers. Yet not a modeling specialist.

My toolkit today consists mainly of Adobe Illustrator, which I became very friendly with in my time as a cartographer in the late 80s, when things were still being done by hand using copy cameras and rubylith paper, and of course Blender.

I look forward to making your virtual and possibly occasional meatspace acquaintance through this institution as I forge ahead in my quest to squeeze as much detail as I can possibly get into jewelry sized objects using 3d printing.

The printing costs would depend on the size and material. It's probably a lot cheaper to buy them on amazon or a hardware store

So I'm attempting to design a model for color printing. I have the file completed and exported as VRML and I have uploaded it (seemingly) successfully. However, I've noticed a couple strange issues.

First, some of the UVs are warping. Most of them are fine, but maybe 2% of the polygons are messed up. The issues are localized to two shells so I'm thinking there must be something wrong with those shells but other than the texture warping they seem completely fine (and Maya reports no issue with them).

Second, and even stranger, when I view the model using Shapeways' 3d viewers (both the one on the product page and the one on the edit model page) I sometimes notice a tiny duplicate of my model located at the origin. I've gone through the VRML file manually and re-exported multiple times with all history and transforms reset and yet I can't find an explanation for this.

Does anyone have a suggestion on how to fix these issues? Thanks guys!

The Shapeways renders are usually very accurate representations of the files SW has received, or at least the files after they have been fixed by SW's software.

If you see a dupe version at the origin it is highly likely you are exporting that dupe, so I would look harder in Maya to find where it might be coming from. Maybe try viewing your VRML file in another piece of software for confirmation.

The UV mapping will not work if the geometry available (i.e. with another shell) does not match the map exactly so I would concentrate on the extra geometry first and then see what happens.

Mesh merging seems to have issues with UV maps. For other materials you can save work and headaches by not merging (SW does it after upload), but for FCS, it's a risk. Are the two shells overlapping?

This would be great when you are entering 10 different models of rings and the only difference is finger size.


This is what Pete said in one of the https://www.shapeways.com/blog/archives/17266-3d-print-in-ny lon-with-selective-laser-sintering-part-1.html]blog post series about 3D printing:[/url]

"Hey s_f_x,

great suggestion! This Wed the second post of the series will go live and I will definitely talk more about multiple parts. Stay tuned and you may be surprised :)

So yes, we will be working on a way of improving multiple parts, and thus also easier way of showing your models in your shop (not having 10 models displayed on your shop which is actually just 1 ring in multiple sizes)

@chillyche: Thanks for the compliments.. I know that the ultra tiny details really stretch the limits of what is feasible, and my items have been a reall challenge at times for the production team, but if I can't make it move then why bother? <GRIN>

chillyche wrote on Wed, 27 August 2014 22:54

Have you worked at all with bits that need to be assembled after printing?


Not a lot. I've got a couple of houses where the roofs fit on as a 2nd piece, etc, or a train car is in two pieces, but rarely have I combined that with the ability to move (articulate) also. I'm sure that I will do some in the future. <grin>

And Ice1 and Ice9 (mentioned there and in SW's blog). More money (7,500 & 19,900 GBP without VAT) but also bigger build volumes (20 x 20 x 25 cm & 30 x 30 x 45 cm) and different laser.

Ah ok that was the ticket mkroeker,

it's a x3d file done in Blender (Internal not Cycles, can we use Cycles?) so I made the diffuse and specular colour black and got this result for the Digital Preview image.

http://twistedpancreas.com/3d/harrier/colours2.jpg

Now I have these black dots all over it, is that because I made the specular black?

The 3d rotation looks right, ie here:

http://twistedpancreas.com/3d/harrier/colours3.jpg

Now I just wonder if I print it or not, especially after viewing a few others posts and their results :(

That "spots" are rendering errors ... I guess from older Blender 3D version used for rendering that.

So don`t worry they appear to others but not on prints. It is a Blender 3D Internal renderer err ... can`t remember what version was this particular "bug"

Manufacturing it is not rendering.

Use only Blender Internal material settings -> .x3d export does not support Cycles and won`t be anytime

Because SW uses something else.

And because Cycles is too new that some features are not supported by Blender itself (or weren't until recent versions), so you are only wasting time trying to figure why export went wrong, why colors look off, or baking is not working, or this or that.

SW only cares about the basics, vertex colors or UV maps, in the subset of supported formats (.obj supports UV maps, but not when SW loads it, for example). In some cases, checking can be done with a text editor, or some other simple tools. Cycles is just overcomplicating workflow if all you care is about printing in FCS.

Also, the noise issue doesn't appear on the grey render, does it? It could be a bug (there was one about black dots, appearing anywhere... your image shows them on the plane only) or an extreme texturing issue (it can happen when you go nuts with high freq noise to try to simulate dust). If the plain old grey render shows OK, then it should be OK.

This is not true, at least for Vertex Painting at Rel 2.69, as we discussed in another thread.

I am trying to create a set of one-off bespoke buildings for my model railway, in 1:148 scale, based on the real buildings in a small valley in the UK.

I am new to this 3D Printing lark, so have been experimenting with the CAD process, and with the printing exercise. To understand how well it worked, I drew up a small "building", and sent it off to Shapeways for printing in WSF(Polished), FD and FUD. You can see the results in photo 01, with increasing quality from left to right.

index.php?t=getfile&id=69472&private=0

The detail of the FUD looked really good. Yes - I am pushing the quoted boundaries of the FUD guidelines, and specified "Print It Anyway", but (for example) the tiles on the roof were well obvious (photo 02, with a coating of primer to show the detail):

index.php?t=getfile&id=69473&private=0

So then I proceeded to draw up the first proper building (the pub), based on much of the same CAD details - for example, the same roof tile drawing. But when it arrived back from Shapeways, I was disappointed to find that the resulting model was not nearly as good. Photo 03 shows a similar roof close-up (again with some primer to show detail) - there is a lot of extraneous horizontal striping, and the tile details are barely visible:

index.php?t=getfile&id=69474&private=0

So does this mean that I was just lucky with the quality of my initial print sample, and that there is inevitable variation in print quality between one run of FUD and the next? Is there anything else that I can do that would improve the result of my resulting 3D models? Would I get any benefit from specifying the orientation for the printing, for example? Or should I be looking for another process to give useful results?

Thanks
Rob
