Would it be possible to have a ceramic model printed and skip the glazing process?

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

I have a question about a new model I uploaded:

On the preview image and in Shapeways 3d viewer the model's eyes are gone.

I tested file in three 3d apps and none of them are having this issue. I checked normals and they are correct.

Will it print like this?

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,

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.

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:

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.

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,

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:
Home » Support » Feedback » New Material für objects mp;start=0&S=2c0ea75a372f131596fc926e93cb6996
Home » Community » General Discussion » Mcor Matrix Paper Printer (older thread) 023a09984cc2342a770acbd7f&th=491&goto=1943

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:
But sadly it's just an april hoax Grrr Smile

Nontheless cool ice printing is possible:
( 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?

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 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. (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.

I wonder what to consider when designing a metal part. Peter told me details of 0,1 mm will show. He also told me to have wallthicknesses of at least 3 mm (maybe a little less for small products).

When designing the housing of something like a fountain pen such object becomes enormous and very heavy !
So, what is possible with the metal printing technique Shapeways is using and how is it effected by the printing direction? Any specs on this ?

Hello, i'm new on this great site and have a question.
I want to use the material White, Strong & Flexible for my design: Inward.
However It was not possible to select PA 2200.

Uploaded two other files to explore the problem.
half Inward:
They could be made out of PA2200.

Now i suppose the space inside the model Inward under the rim and bottom (ca 5mm) is too small to pour the powder out of the product.
Is this correct and must there be another hole in the product, or did i simply made somewhere a mistake?

Thanks in advance ...

US researchers are researching casting wood like a plastic for 60 years. But they did not succeed .
Wood contains 3 main material , lignin , cellulose and hemicellulose.
Special material which makes wood strong is lignin.
German Fraunhofer Institute finally succeeded to add some chemicals in to the lignin and produce heat meltable and seting wood with it.
But they keep the formula secret.
They sell this heat meltable wood with german Tecnaro company.
You buy the cookie size wood pieces from them , melt and do your job.
I think they cost 5 dollars per kilogram , produce ebony density and comes with many colors.
If you make a powder from it and print objects with wood , it would be lovely.
It melts 60 Celcius degrees.

Best ,

I have a little "problem" with wall thickness....

how do you calculate the "limit" of printability of a model ?
I know there's 1mm min for "dtail" and 0.7 for WSF, but... sometimes I don't know in witch case we can pass through this.

Here is an example that will be clearer :
If I want to print a "cone" of 3cmx3cmx3cm.... the end of the cone is going smaller and smaller... and it pass always under the 1mm limit !

other example :
Here is an Ogre..... (picture below)
It's a 3.9cm figurine.... it has passed succesfully the "upload" checks...
but the staples of the shoes are only 0.5mm thick.
Will the model be "unprintable" or "printable" ?

Finaly a last question : is the limit fixed by the printers or is this a limit you've decided to assure resistance ?

I've just received my first part made of WSF, and on a first inspection I have a couple questions that some of you might be able to answer...

- the part is slightly distorted (bent) in one of the axes. About 1mm on a 160mm length. Is that to be expected as part of the process and the achievable precision, or it just didn't turn out completely Ok ???
- Also, the model had a hole with a 1mm diameter, and it didn't came out. Was it too small ?

I know they're rather new, but I was hoping for some details about the two new metal printing options; particle size, level of achievable detail, min wall thickness, sintering temps, post-working possibilities and experience, etc.

Even anecdotal info would be greatly welcomed, as I hope to produce some rather small & complicated items in either metal over the next few months.

I was initially planning to produce the designs in PMC silver from a silicone mould. Being able to go straight to steel would solve some serious strength issues, but being able to effectively work the piece to add detail and improve surface finish is critical.

Yes, I am keeping an eye on Whistler's new thread. Smile

Hi Guys, most of you know I get a real kick out of this service and community... I was just thinking about future directions for the media and I came upon a few things that I personally would definitely pay extra for in prints.

The main ones are as follows

    Higher polycount
    Finer printing layers
    Choice of print direction

Some of these options would massively improve my end use of the product and personally I'd pay a premium for these options separate to the service I already use happily.

What do you guys think? Any ideas?

I just received my Shapeways model, and the model was.. deformed.


It was half the correct size, and squashed. At first I thought something must have gone wrong at Shapeways end, but after checking the 3D preview closer it turned out that my export was to blame. I had to apply 'reset xform' in MAX in order to correct the shape.

So as a cautionary tale, if you don't want to waste 22 like I did, be sure to double check your model in the 3D viewer. The preview angle made the model look correct, but upon closer inspection it was clearly very squshed.

This was an xmas gift for someone, so I hope my replacement gets here in time for me to paint it.

Fusion Imaging has created a mount for the iPad Mini for DJI Phantom drone flyers.

We worked hard on this one to get the thickness and strength right, and we are really happy with the result.

It looks great, and performs like nothing else. The grip on the iPad is phenominal, so much so that we made a video to demonstrate just how well it grips.

Today we released Click-On Leg Extenders for the Phantom.

There are a lot of leg extenders out there but we'd like to think that ours are uniquely designed and innovative. They literally just click on and off the legs of the DJI Phantom Drone.

These are a 'straight' design so really only suitable for the Phantom 2 and Phantom 2 Vision.

We will be releasing a 'wide' version soon for the Phantom 2 using GoPro and Phantom 2 Vision + where the legs are angled out to take into account the off centre camera of the Phantoms so that the leg extenders don't show up on your video footage. r-straight-for-dji-phantom.html

Hey guys,

For the enthusiasts out there we have created a 'Flytrext LIve' mount for the DJI Phantom multcopter.

Basically the Flytrex Live is a black box, so for the enthusiasts out there its a great accessory to log all your flights. We designed this from a customer request. Its great to have customers out there who love what your doing and want you to make things for them because they cant find it anywhere else. This is the kind of work we love to do at Fusion Imaging.

You can find it here or-dji-phantom-quadcopter.html

So, from the beginning of time, I've wanted a Legion of Superheroes flight ring. Well, okay, not that long, but since my teen years, maybe earlier. When Shapeways first started, I stated regularly looking for such a ring. I found designs I liked and bought a few in a variety of materials. I had one made of stainless steel which I had laboriously hand-sanded to a sweet satin finish. Then I lost it in Las Vegas. (Not lost as in losing a bet. Just misplaced it.)

Eventually, I realized that I needed to make my own. When polished brass became available, I knew it was time to start.

Alas, my artistic skill are next to non-existent. Luckily, there's OpenSCAD! After a lengthy learning period, I managed to make a nice looking Legion logo, based on my favorite renderings from the comics. I printed that out in steel and yellow plastic, as a proof of concept. The results were promising:


With a good-looking logo ready, I needed to make the ring body. I printed out three different designs, taking advantage of the "Print It Anyway" option to test a variety of ways of dealing with some sharp edges. This also let me verify the sizing. I ended up choosing the one on the right:


Meanwhile, I needed a way to add some sort of black inlay around the logo. Some Googling found me EFColor, an enamel powder that melts at a mere 300F. I had to order it from the UK. Once it arrived, I tried some red inlay on the steel test logo. My clumsy method was to sprinkle it all over the logo, then brush it off the face with a business card. Two applications of the powder do the trick, leaving a glossy smooth surface.:


Having chosen a ring body from my yellow plastic tests, I ordered it in polished brass. With trembling hands, I opened the package, delighted with the quality of the result:


Finally, I filled in around the logo with black powder. Some stray flecks remained on the face of the logo, but these were easily removed with a brass scraper:


I am unreasonably giddy every time I look at it. If only it could actually make me fly!

The customizable lightning bolt bottle opener came about at my company's monthly Beer-O-Clock event. Everyone was always looking for a bottle open so myself and a co-working came up with the idea of creating an opener based on our departments lightning bolt logo. It can be personalize with a short name or initials and is a great gift for the holidays or special occasion. Thank you for considering the customizable lightning bolt bottle opener to be feature this for the holidays.
