Now we know all we wanted to know about Romanian home decor - though on second thought, what is in that floral picture frame - roaring deer ? :-)

Hey all,

So I ran into this problem using Sketchup when adding colors to a model via "Vertex Painting", which is "simple colors applied to faces or corners of your model" (Thanks mkroeker!).
Naturally, adding the colors went okay in Sketchup, but when I uploaded the .dae file of my model onto Shapeways, the colors of my model are all distorted. (See attached pics)


index.php?t=getfile&id=65973&private=0

And this is what it looks like on the product page itself:

index.php?t=getfile&id=65974&private=0

And of course here is the model in Sketchup:

index.php?t=getfile&id=65976&private=0


I was hoping to know what exactly the problem(s) I am having and how I can fix it. Thank you!

Make sure that the orientation of the faces (face normals) is correct (all pointing outward) - your model looks like about half of the body panels were bolted on with the undercoat (back side of triangle) showing instead of the paint job. If that alone does not fix all problem areas, look for overlapping faces or small holes/seams in your model that shapeways' site software may be trying hard to correct for you.

Hi Kevin!

Nice to meet you and thanks fro sharing your nice pendants!

If you have some time would you mind to explain in some lines what are your interests and how you use 3D printing. Which kind of software do you use to design your models?

We are focus in scientific related jewellery as you can probably can guess from the models we sell :)

We are planning to organise a meeting somewhere in fall with all shapes from Belgium, would you be interested to join and show us your jewellery?

Cheers

My model "Doxie: Cute Pup" at https://www.shapeways.com/model/675137/doxie-cute-pup.html?m odelId=675137&materialId=62
Apparently can be printed in any material other than Ceramic (due to thickness issues)

There seems to be no way to remove ceramic from the list of available materials for this model

Why?
How would I remove the ceramics category for this model?

Ceramic may be an option for YOU from your signon, but it is not an option for the buying public.
Try logging out and see if you still see Ceramic.. I do not.

 Topic: Best way to apply vibrant colors to Full Color Sandstone

I have been printing some models in Full Color Sandstone (FCS) and have a couple of questions about the best file format to export the models. I am from a computer aided design background, currently working with ViaCad9 and have no experience with UV color maps. To apply color, I have been setting the color of individual parts that make up the model and exporting using VRML2 (.WRL) format. Similar to the Radioactive Barrel posted below.

index.php?t=getfile&id=65952&private=0

Assuming that I am not interested in more complex coloring (like gradients), are there any advantages to importing the model into other programs and creating UV color maps?

Sometimes, I feel like the colors I print do not always seem as vibrant as some of the colors done by other modelers on Shapeways and I was wondering if it was related to not using color maps.

I am willing to learn UV mapping, just not sure if it is a good idea for simple color schemes of parts. Appreciate any thoughts or suggestions.

UV maps as such will not automatically make your colors more vibrant, all they do is provide a (relatively) easy means to add gradients and surface details that do not have to match the underlying mesh. So for your barrels, it could be that you are simply using a wrong shade of yellow. The zcorp printer does not reproduce all colors equally well - there are a few test palettes in the shops to check this and make it easier to find nice looking RGB values. If on the other hand you wanted to make a very rusty version of your barrel, uv mapping would be the only way to paint the spots on, unless you made your mesh extremely detailed just to have vertices in the right place that you could assign the colors to.

mkroeker,

Thank you for the reply. I hadn't thought about the printer not being able to print all colors equally well. I will have to search out some of the test palettes you mentioned in some of the shops.

I was reading the tutorial at the link below and it said the ZCorp printer Shapeways has uses a CMYK color scheme. Do modelers find their colors come out better in FCS if they generate UV maps or VRML files using CMYK color scheme since this will match how the printer determines colors?

That question is a bit academic as VRML supports RGB colorspace only (as do the supported texture file formats as far as I know).
On the topic of palette samples , stannum has a nice one here that is accompanied by an image of the colormap on the model page so you can pick color values from it directly. Another set by kaetemi is here. he suggests scanning the actual print to create your own colormap file from it. (Somehow stannum's approach seems more logical to me - to choose a visually adequate result from the printed palette and then look up the input color required to achieve it).
Also note the thread linked from the end of that tutorial you mentioned - varnishing the print can improve the colors (probably because it makes the surface smoother,i.e. less prone to light scattering - I was recently surprised to learn that the raw fcs print barely shows colors before the superglue coating is applied)
