I'm preparing to print my first ceramic part, and I have a question to hopefully inform my design a bit. Tip #8 on the design rules page for ceramics indicates that parts should have a clear "bottom" to ensure they are glazed correctly. Does this mean the bottom doesn't get glazed? Does the area of this base get subtracted from the print price? If I print a 10 cm x 10 cm x 10 cm cube, is the surface area 600 cm^2 or only 500 cm^2 (subtracting on face area for the "bottom")?

Hiya, finally finished tweaking my Boris and eliminating thin walls etc. I was wondering if someone could tell me what the best way to arrange the parts in the final file would be. It'll be printed in WSF polished.

The body, legs and bike are all to be printed as a single part. I'm guessing wheels laid flat, same with the bits sprue? What about the body / legs. Laid flat along the same axis as the wheels, or will it be ok standing up (the legs move)

Cheers!

Hello fellow Shapies!

I submitted an order for one of my models so I could take some photos and I received a "dimensions too small" notice about it.

As far as I can tell, the dimensions of both earrings fit in the minimum 65mm total. Though, admittedly, only when accounting for both earrings.

Link to model: http://www.shapeways.com/model/426629/minecraft_earrings__gr ass_.html?gid=ug

Is there something I'm missing or is it a mistake? I can increase the size of the earrings easily enough, but I really like the current size of them and am worried that it will come out gaudy.

Note: the original design was two cubes of 16x16x16mm each. i recently ugraded them to be 22x22x22mm in hopes that it would fulfill the 65mm minimum.

Hi Shapeways and community,

I would like to know the specific weight (per cm^3) of your material "white detail". Most others (such as White, Strong and Flexible; and Frosted Detail) I have found in the material data sheets (0.93g/cm^3 and 1.02g/cm^3 respectively), but I can't find that info for "white detail" (fullcure 830). Even the "objet" web pages seem to ignore that.

Thanks for any information!

Hi Smile

I am trying to create a large hollow sandstone object (it will be full color). I want to make full use of the print size and my model nears 20cm cubed - and is hollow.

My questions - How thin can I realistically make the walls of this model.

Is the price calculation on this model taking into account the hollowness?

Any other tips that I can glean?

Many thanks,

Matt

Hello,
I haven't printed stainless steel before, and have questions about accuracy.

I have a coupling nut and a screw, and I need to make a SS hexagonal cap that fits on top of the nut, and goes between the nut and screw.

according to the design rules, the accuracy of SS is 2mm. Is this 2mm in either direction?

The width from side to side of the nut is 12.8mm, and I need the cap to fit snugly. I was thinking to compensate for this variation, I would taper the inside of the cap over a height of 3-4mm, from about 12.3mm at the top to 14.3mm at the bottom. Would this work or do I need greater tolerances?

This cap is one end of a Z-bracket sort of thing. How does orientation affect SS printing? Does it make a difference if the Z is on it's side or upright?

Thanks

I've uploaded 10+ models and successfully printed them in the materials WSF (+ 3 other colors), FD, Alumide, and Sandstone. Now I want to use the Full Color Sandstone (FCS) material.

Through trial and error, email with customer support, and checking forum threads, I have deduced that OBJ files with color profiles are not supported for FCS printing. If I am wrong about this, someone please correct me, to stop me from expending some serious future effort.

It seems I must use VRML2 or X3D to print to FCS. And since I'm not making headway exporting my OBJ files to proper VRML2/X3D using SketchUp/AccuTrans3D/MeshLab/Blender, I'd like some recommendations on the 3D modeling software I should use to achieve my objective.

Q1: If you have successfully printed a model using Full Color Sandstone, please tell me what software and format was used.

For my application, the 3D modeling software must support some type of user-specified computation to transform an imported model.

Q2: If you have an opinion on which software/format is best suited for my purpose (3ds Max, Maya, Rhino, ...) please tell me.

Thanks...Jeff

P.S. Up til now, I've used SketchUp Pro 8 to generate all of my models, exporting to either STL or OBJ. I've had to write support software and use/modify various SketchUp plug-ins, because the patterns in my models are computed, based on Wolfram's Automated Cellular Automaton (see attached photo of a model printed in FD). I've tried numerous times to export VRML from SketchUp, following suggestions given in the forums, to no avail. Models that successfully export to OBJ format, when exported to VRML format, are either corrupted or incomplete or just wrong, when examined using AccuTrans3D, Blender, or MeshLab. Same with OBJ files exported to VRML from the latter 3 programs. This is why I am asking for help. If you know some magic to make SketchUp or these other programs export proper VRML, please advise.

I was happy to receive my prototype in White Strong and Flexible, but couldn't help but notice it was sponge-y and a bit more frail than I expected. In my tiny mind, I was thinking something more like a typical PVC part having no experience with this.

My challenge is complex here because I am trying to make things that are tough, flexible, but actually quite small, and require tolerances close to what you're spec'ed to. So the .3mm shrinkage I noticed has impact. It's do-able, I can work around it, but it's at this scale dimensional tolerances are tough to manage. Would Alumide be even harder to work with then and more brittle?

Is there any material or process I can use that is appropriate for small run productions for parts that require fidelity to detail to even .1mm? And I also wish to try metal (I'm guessing your steel process probably isn't appropriate for this granularity). I was thinking perhaps something that required stereolithography then making a mold out of that somehow.

Unfortunately, I'm only an armchair engineer, so feel free to use small words. Smile

I'm interested in the question of whether Shapeways will offer other glaze options (colors would dramatically enhance the appeal of the ceramics, particular for larger surface area objects that are expensive for which decoration could increase customer perceived value dramatically).

There are some fairly easy to apply and user friendly FOOD SAFE glazes that often make spectacular looks to ceramics.

Hi guys,

Sorry if this in the wrong forum section, I wasn't sure where it fit best. On the shapeways ring creator, are you able to download your model after it's created? I want to be able to adjust it to a half size, so I'm hoping I can download it.

Since we have the ring co creator, any plans to do a bracelet style bangle in the future?

Thanks for your help!

Hi guys,

I've created a model (units: meters), baked a texture in it, and it looks correct in 3ds Max. But I can't get a reference to the accompanying texture to be included in a VRML97 export from 3ds Max. A texture reference is missing in the output file.

I've tried adding the texture reference manually to the VRML97 file with a text editor, but then Meshlab gave me errors about missing or too much parentheses, which I couldn't get fixed.

A Zip with the 3ds Max 2012 file and texture can be downloaded from here. Any help would be appreciated.

Many thanks in advance.

I printed an item in FUD back in June and I have just discovered today that the item is too short in the X direction (only) by about 2%. Unfortunately I didn't check immediately after receiving it so I don't know if this was a printing error or it has shrunk since. I have checked the key measurements of the STL file in netfabb and they are spot on so it is definitely not a model problem.

Has anyone had any similar experiences or suggestions as to what I can do?

on my Honey Ring and honey ring skinny I've had a customer have the same issue twice in a row. The issue is the hexagonal nub that protrudes at the top of each ring is a design intent and it gets ground off during finishing. see picture

index.php?t=getfile&id=10625&private=0

After he reported this once and got a replacement the same mistake was repeated. I've ordered several of these and have not had this issue; each of my rings have been ground at the bottom. So I need more consistency in the finishing of these rings. Are the people doing the finishing looking at renderings or photo's of the design so they know what's a feature and what was added for casting?

Hello,
I am wanting to make a part in Alumide (am firm on this for good reasons) and I want to make interlocking parts such as plain bearings.

I want to know if anyone else has done this in alumide. I know that people usually leave 0.5mm (I think) in SWF for this. But Alumide also gets shotblasted post-process and I want to know how much to take into account.

For example, if I was making a piston/cylinder set in SWF I would make the piston 10mm in diameter and I would make the mating cylinder 10.5mm in internal diameter.

But what about alumide?

Would love any advice - otherwise - I wil start research I guess.

Hi would you have any insight into growing problems using the Aureus? Here is what happened to me.

The green wic100 has had a problem of bonding to the lower tray onto the silicone(switched trays and used pic100 and it happened too). Now this maching has been zero'ed out and I don't think that is the problem. Maby somehow the model broke while growing. Also there is a battery backup on it. Now those trays are not cheep. I just thought I would check with people that are experts with this stuff.

I ususlly run the models overnite so that makes it hard to see whats going on.

Thank you

Does part orientation need to be considered for round-bodied objects (created by a revolve or spin) in order for them to print properly? See the image below for a simplified version of what I'm talking about.

Hi there,

I just received a model I ordered in strong black & flexible - it's a little box with a sliding lid.

The sliding lid consists mostly of one big rectangular sheet, about 157x106 mm and 1 mm thick.

Sadly, one of the long sides is close to 1 mm longer than the other!

While it is easy enough to correct with a sharp knife, it is not the accuracy I hoped to see (and makes me wonder what the impact will be on other models I have planned to print).

Is this deviation (157 -> 158 mm in 106 mm across) normal or did something unusual happen there?

Thanks & regards,
Christian

Hi

Just wanted to check out some of the information on your Materials page.

The Material comparison page states:
Heat resistance = 80/176 ºF.

Presumably this means 80 °C / 176 ºF (since the conversion is accurate).


But the datasheet gives very different information:
Thermal properties
Melting point EN ISO 11357-1
172 - 180 °C

Vicat softening temperature B/50 EN ISO 306
ASTM D1525
163°C / 325°F

Vicat softening temperature A/50 EN ISO 306
ASTM D1525
181°C / 358°F

This is important because dyeing WSF parts involves boiling them at 100°C. I have done this many times and have never seen a part soften, even slightly.

I suspect the information on the Materials page is wrong.

Regards
Richard

Is there any advice yet for what is an acceptable ratio for length and thickness for this new material yet?

I've had a few problems in the with this as some of my models have sub 1 mm square sections in them .

Somewhere between 10:1 or 12:1 seems to be the limit in WSF . White detail seems to be less but I've not used it enough to get a definitive answer.

Hello all,

I'd like a suggestion,

I have a 3D printed phone case that I made with Shapeways, we used "Black detail" but the parts came back too flexible. We intend on using Polycarbonate with a percentage of glass fiber for regidity in the finished product. However we need to make a few "testers" to send out to people. Shapeways suggested Alumide or "Grey Robust".

However, I'm worried that Alumide is too brittle, and Grey Robust won't have the detail needed in a small part like a phone case.

I guess I could sand the rough edged of "Grey Robust" if it's an issue, what do you guys think?

Hi all,

I've been thinking of trying Shapeways for a project soon as was wondering what the best material would be to print this item:

http://www.urbanchant.com/temp/dish.jpg

It's a dish, 8.5cm wide with 2mm thick walls and a ring of knurling around it. The final finish will mimic the look of machined aluminum. It will need to be able to stand up against a little bit of handling from time to time but it doesn't have to be completely rigid. I'm familiar with polyurethane casting resins and such but I have no idea how WSF, alumite or the other printing materials compare. Also, I do need a fair bit of smoothness so I was thinking that I might be able to undercoat with some spray filler to fill any pores if you all think that would work. I have already ruled out stainless due to the cost.

Thanks!

polyurethane synthetic resin would be awesome to have. then people could cast dolls. It would be neat to have it in a few colors as well.

but in the meantime, For people who has played around with the different materials, what would you say is the best match for this?

I want to try casting a doll, and the type of doll I'm trying to make is cast in resin.

I am working primarily in Sketchup and Rhino on a Mac and am looking for the best workflow to post files to Shapeways.

I have come across plugins like CADspan for Sketchup, but feel that there may be something better just in the export settings or file type (.dae, 3ds. stl) from Sketchup and Rhino which would help to reduce the cleanup in other programs like netfabb.

Any guidance would be much appreciated.

I was discussing 3D printing with a friend today in relation to a project that I am working on.

Her comment was that nylon when molded via traditional processes ends up with a fair amount of internal stresses in the finished part. These are typically relieved via some form of heat treatment (eg. boil in water and let cool slowly) post production.

Examples of applications where this was important was propellors and impellors that had a tendency to fly appart if not appropriate processed to relieve the internal stresses.

I know a lot depends on the precise material, and exactly how the material is processed, when it comes to issues like this.

So my questions are:

1) is any requirement for stress relief with the WSF material as processed by the SLS process?

2) if so, is it done by Shapeways?

3) if not, then what is the recommended procedure?

Many thanks,
Tim

Hi,

In the last livecasts you presented the superb new high detail materials which are to expect.
Now to complete your offered material options it would be great
if you would make the other end of the size spectrum accessible too.
(sorry to burry you with work suggestions)

In the Forum there seems to be quite an interest in cheap large scale printing:

I'am interested in larger scale printing too,
so I thought about what process could be cheap in terms of material costs
and had a pretty unusual idea, which I want to share.

You could try out the following:
First print a negative form out of Water-ice
then use this form as a cast for a suitable resin.

Has this been tried or has been thought about it?

An experiment wouldn't take much effort if that where true:
http://www.shapeways.com/creator/icesculpturecreator
But sadly it's just an april hoax Grrr Smile

Nontheless cool ice printing is possible:
http://www.arch.mcgill.ca/prof/sijpkes/ice/
( you could fund the researchers there Wink )
Or is there already a comercial version of this aviable?

The benefits would be:
Water & Resin should be pretty cheap.
With different Fillings (possibly cheaper then resin) a multitude of materials could be produced.
The Removal of cast happens on it own => no manual cleaning labour.
The shape of the cast doesn't restrict the design space!
The detail should be acceptable although
detail isn't so critical for larger scale objects.

Of course some problems could arise:
The exothermic reaction heat may melt the ice.
Resin which cures at subzero temperatures probably
won't be as cheap as the one used in masses for boats?
With a quick search I found resins with a minimum curing temperature of 2°C which might work.
The manual handlig of resin may be too expensive.
Low temperatures rise the resins viscosity and so rise the minimum wallthickness.

What do you think?

to Everyone

I just uploaded a textured mesh to shapeways(maya export dae file format), but the uploaded mesh cant show texture in shapeways. can anyone try it before? And teach me how to upload a textured mesh.

ManyThanks

Short question;
Is it possible to print thiner parts then the specified minimum wall thickness, if it is not critical to the whole model stability?

I know of http://www.shapeways.com/model/96574/evil_purple_tentacle.ht ml where the tentacle/arms are a bit thinner.

I was thinking of smaller metal sew-on emblems and full color sandstone model figures for model train stuff.
http://www.nottoxic.com/wapcc/ae/aqua/thinprint.png (just quick sketches)
As they are so small themselves that there is nearly no weight/force stressing these parts, would it be possible?
What is the minimum tollerance?

Hi everyone. I modeled a custom ring in Rhino, which I wanna get casted in gold (it's like a family ring kind of thing), and I need an acutal solid model. From what I understand the best option for me would be wax printing, in order to use the wax model with the lost wax casting process, but as you know, Shapeways doesn't offer that material.
What are my options then? I saw they offer different kinds of plastic materials, and stainless steel. I just want the model to be detailed and the surface to be smooth.
Any advice would be appreciated.
thank you

link to the Image

The top picture is incorrect in Blender but correct in the site's preview image.
The bottom picture is correct in Blender, but the normals are inverted in the preview image.

Will one not print? Or will the printer treat both versions the same and ignore the normal directions? Which one should be used?

This is odd as I've uploaded meshes made with blender before and never had this problem.
