Vapor Sanding is a great way to smooth ABS 3D Printed models, we all know that. The difficult part is finding an easy, no mess way to do it. The Touch-Up is exactly that. We have launched a campaign on Indiegogo and wanted to share it with you. Looking at the posts, I think you will enjoy The Touch-Up. Please comment and let us know your thoughts! We would love the insight from others who 3D Print.

I have gotten some fashion accessories printed in blue strong and flexible.

I find the color gradually fading and becoming duller, even though it has been carefully used only several times and stored properly.

1. Is there a way to maintain the vibrant color for the new models that I am about to have made?
such as using a certain kind of coating?

2. Is there a way I could revive the color of the faded model?
I saw some online tutorial of rubbing moisturizer to resin jewelry. Could this be applied for the strong and flexible plastic?

Thanks a lot in advance!

Curious if anyone has experience with this (lost wax casting of the FUD material).

Very small pieces.

Thinking it may need platinum treatment?

I understand that white sandstone can discolour if exposed to UV light - would anyone know what type of treatment/sealant etc I can apply to it to prevent this happening, as I'm making the part for a customer.

Thanks.

Hello;

I'm a car restorer, and I'm currently working on reproducing a gauge bezel for an old car; what material might give me the best results?

I need it to be plastic, black color, smooth surface and sharp details. Also, must withstand mild temperatures from being inside a car in the sun.

Any ideas?

Have a great week!

Hi! I am new here, just thought I'd say welcome to all my fellow Shapeways buddies Laughing

I ordered a coloured sandstone figure a while back. I am basically wondering if it is strong enough to withstand resin casting, as I want to make a sturdier model of it and uniquely custom it. Here is what I ordered:

Hi There,

I have a question. I'm getting married in a couple of months and designed our wedding rings. Now, I'm wondering if they will turn out OK if I order them in premium silver (if that's still available). Anyone here who has more experience ordering premium silver that would like to give some feedback on my model? My concern is if they can do a descent job on the polishing seeing there is a geometric relief on it. The model isn't perfect yet, but the screenshots will give a descent impression.

anyone?

Does any one know of a good company to out source products too for post production? Say, once you've gotten a good model and you're happy with it, but you want to up your game and produce more than just a couple, or make them for even cheaper at a higher volume... anyone have any links or referrals?

I'm looking for plastic or high impact resin.

I ordered the thorn dice with decader in black as a present for a friend. I was a bit disappointed at how hard it was to read the numbers on the dice, so I bought some orange acrylic paint and applied that to the numbers. I've touched it up a bit since I took this photo, but I was very pleased with the result:

http://i.imgur.com/U515EdY.jpg

The 7 on the 8-sided die seems to have an error, or maybe it was just awkwardly modeled, but other than that I'm looking forward to giving this gift.

Edit: In retrospect... I'm not sure if this was the best sub-forum for this post. If a mod thinks this would be better suited elsewhere, please feel free to move it. Thanks and sorry for any trouble!

Hi everyone,

I am working on a series of 4 large sculptures, produced in WSF. Some of them were actually a little too large for the machine, so there are some small parts that need to be re-attached. I plan to spackle the join once it has been glued, and spray-paint the whole thing. I did this previously on one piece that did not require gluing, and was happy with the result.

I also received one model with a visible line that runs across the whole of the piece, where the two lasers needed to print it did not quite line up. So far I haven't had a whole lot of luck sanding it. I was reluctant to use very coarse paper as I didn't want to scratch the rest of the surface. So my questions are:

-What's the best glue for gluing two parts that are 6mm thick to each other? (I saw in the archives that some people recommended 4 hr epoxy? Any updated recommendations?)

-Any spackle recommendations?

-Lastly, what grade of sandpaper have people used to sand down problematic areas on their models without actually polishing the whole thing?

Here's a previous piece so you can see the kind of object I'm talking about.

Thanks!

I just received an order last week and haven't been able to post about it until now.

It's hard to get a 100% perfect print. There's likely to be a small blemish. Like an LCD might have a dead pixel. Though, if I a dead pixel is in the center of the screen, it becomes a big issue. Sadly, that's what happened with this print.

This print has some kind of white goo (glue) stuck on the character's face. So you always see it every time you take a look. The rest of the print meets standards ( great colors, smooth, no chips, etc.)

The blemish seems solid and I don't want to try scratching it off. Has anyone had to deal with this issue? Any techniques?

I normally wouldn't complain if it was more hidden. Right on the face just ruins it, almost no different than physically damaged there.

I'll e-mail service for suggestions and what they think.

After reading all the advice and horror stories I could find on the forum, I tried painting my first FUD products - two ship models and a model of a Bloodhound missile. I washed all three with warm water and mild hand soap and let them dry thoroughly. I primed them with Game Color white acrylic primer and let them dry for several days. I painted the ship models with enamel paints (that's what I've been using for the last fifty years). I'm almost done with the ships and things are going well. When I tried painting the missile with white enamel, it seemed to dissolve the primer. I scrubbed the missile as best I could with paint thinner and put it to soak in brake fluid. (That's the most benign way I've found to remove enamel paint from plastics.)

The only difference between the ships and the missiles is that the former got two coats of primer, while the latter got only one. Should a second coat of primer make that much difference?

I'll let you know what happens to the ships after they're Dull Coated (I'm not expecting anything bad with so many layers of primer and paint on the FUD). I'll also let you know if the missile model survives the brake fluid bath.

I encourage designers of small-scale airplanes to offer all their products in WSF. Detail may be lost but WSF seems to be a much friendlier material.

I am starting a project to make a steel investment cast part. About 2" x 1" x 0.5".

I'm thinking in the few hundred parts range, it will end up fitting in an assembly of mechanical parts in a machine, so here are my initial thoughts.

1. Shapeways makes a master.
2. I build a form and cast it in RTV silicone.
3. I got a little wax injection molder, so I shoot waxes
4. I send them off to a foundary to get cast in tool steel
5. I finish machine (reaming a pivot hole, and touching a surface grinder to clean up one edge).
6. Send out for heat treat.

So, my questions I can think of are:

1. What material is best for my master? Presumably I want the best surface finish, though I could clean it up by hand.
2. Shrinkage. I assume 4%, though I would not apply shrinkage to my pivot hole, so it is 4% undersized, leaving enough meat for the reamer to clean up.

What am I missing?

Sometimes in with a metal 3D printed object,you get some green material stuck into the small cavities. For instance, in a die, you can have them in the indented number.

I made a video to show how to clean that with a simple needle.

Hey guys, I've been trying to find a reasonable way to paint the nylon 12 white strong and flexible, and many of the topics here have been interesting, however, they all are for very small pieces.

I'm working on a large piece, and by that I mean, 16 inches across, by nine inches, by three. Unfortunately I cant dip this sized object it Rit Dye cost effectively, and I wouldn't want to brush paint it as I want an even coat.

So far, I was thinking of just lightly sanding, then primering with many light light coats of spray paint, followed by many light light coats of black paint. I don't know if there is a specific kind of spray paint that would work better than others.

Any advice helps, I'm open to all the different suggestions. Thanks!

After you get your nylon PA2200 in white, as its porous material, it will turn into yellow right?
So if i use acrylic paint will it prevent from discolouration?

What if i rub two layers of nylon PA with each other, will the surface corrode?

Hey guys!

I saw a while back there was a thread here where someone had cleverly laid polymer clay in grooves of a stainless steel piece.

I decided to have a crack at doing the same, and also bought myself a rotary tool with diamond burrs to polish it all up.

I first roughly polished the external parts of the ring (leaving the inside intact for character). I then smooshed the polymer clay into the grooves on the ring, making it all as neat and flush as possible. In the oven at 200ºF for 20 minutes or so then let it cool. Once cool I finished up the grinding and polishing.

Here are the results using black polymer, and also a granite looking polymer with grit mixed in. I like them a lot Smile

Hi all,

For our end product, we are creating a low production run of slip-cast ceramic figures. We want to 3D print the original models and cast plaster molds off the models.

Does anyone have experience creating this type of mold from the prints? We are trying to figure out which material will be the best for such a process (& if this print can be shelled out). Keeping in mind the possible warping from the plaster casting process. (We are trying to avoid having to make a silicone mold & recast in plaster.)

Please let us know if you have any info.

Thanks!

Hi all!

I am building a wooden model ship and I would like to print some decoration parts in FUD. I already modeled some parts and ordered them to check the quality.
The only thing that concerns me is the durability of the material. I intend to paint the parts with acrylic paint and glue them to the hull. There will be no mechanical stress on them.

Of course there will be no experience how a FUD part will look like after 20 years..... Smile

But are there some estimates? Will it remain in shape or will it desintegrate and get brittle over time?

Thanks for any answers or guesses!

I used Revell and Humbrol acrylics, over two coats of Humbrol Hobby Spray grey primer #1, and finished with two coats of Humbrol Hobby Spray gloss varnish #35.

I'm not the most steady-handed miniature painter, but give how tiny these are (about 10mmx15mmx5mm) and that they're intended to actually be played with (by adults). I'm pretty pleased with how they turned out.

Dear all,

I am looking to create a matt plastic finish (similar to that of an x-box) for some models I'm making with my colleague.

I was about to upload my first model - a vase, and WSF seems like it would be a great material for it... except that supposedly it's not waterproof. The videos of the material make it look like it would be pretty watertight, but I guess not. Would white detail be the only plastic option if one wanted to put water in it? Otherwise I guess lining it with an epoxy would do the trick, no?

Having a jug of muriatic acid leftover from a masonry project, I decided to test its effects on a few of my spare dice. Sources I found online said that muriatic acid (which is actually hydrochloric acid) blackened and dulled stainless steel and hastened oxidation in bronze.

I dropped the two test pieces into a glass of muriatic acid and let them stew for two hours. There was a fizzy bubbling and the acid turned lime green. Fumes of a foul nature were released. NOTE: If you are going to try this: 1. Wear eye protection and gloves, and 2. Do this outside or somewhere else with excellent ventilation.

After removing the pieces from the acid, rinsing them, and letting them dry, they had acquired a rosy pinkish hue. After a week, the oxidation has deepened to a darker copper tone.

http://www.chuckstover.com/Acid-1.jpg

The first piece, my Thorn Die20, has a lot of exposed surface area and darkened quite a bit more than my prototype Overstuffed Die20.

This method of producing a patina on the stainless steel material is a good way to make them look antiqued if you are comfortable working with powerful acids. If you are not comfortable working with acids, a patina with flame as described in other threads in this section produces a similar effect.

I have recently ordered a part in the transparent material from shapeways. I needed it to be transparent, so have been sanding it (intending to polish) As i sanded, some marks have become apparent in the material. i think they are like bubbles, where the different layers of materials have not fused properly. I have included an image.
I am wondering if anyone else has encountered this problem, and might know if it's possible to use some sort of resin to make the fill the gaps/ make them invisible?
I'd appreciate any help

Hi all,

I have an SLS Nylon PA 12 model which I need to apply a base coat to seal it, and a finish coat.

Can anyone help with particular brands of paints to use for both. I am seeking to either spray paint it or airbrush it.

I would need a clear coat for the base, because the final paint finish I am seeking is a soft white matte coat.

Any help would be greatly appreciated. Cheers

Rick
