MeltWerk is an online 3D printing service for everyone. Your 3D model gets printed with the help of the latest industry 3D printers and we deliver your 3D printout right to your door. Just upload your 3D file, choose your desired size and order within minutes. Go ahead, just try it out now
As you might have noticed, our prices are awesome. How do we do that? Well, we streamlined every single step of our production chain to the maximum. Everything is happening automatically, everything is happening super fast. That also means that there is no manual check of the 3D models (so, please note our design guidelines when creating a model).
Our 3D printouts are manufactured through Selective Laser Sintering (SLS). This process uses a plastic powder, which is fused by a high power laser on exactly the points in space that were defined by your 3D model. And so – layer by layer – a solid structure is created that, in the end, turns into your very own 3D printout.
That was the short version. For more information, please read this.
We use Polyamide 12, also referred to as PA 12 or Nylon-12. It is a thermoplastic and a real all-rounder. It's light and flexible and often it gets used for jewelry, art and design objects, or for gadgets like smartphone cases. But, due to its high stability, it's also suitable for making tools or movable functional parts. Like we said: this stuff is awesome!

White. Everything is pure, classic white.
For small objects, the minimum value order is just 5.95 €, excluding shipping costs.
Apart from that, the total price for your printout depends on three things:
Sounds complicated? Well, it is. But have no fear! You can see your total price all the time during the ordering process. To change the price, just change the scale of your printout (see image).
You can pay safe and secure via PayPal. You don't have a PayPal account, yet? Well, go get one. Get more information on why we love PayPal here.
As soon as we receive your payment, your 3D model gets processed.
After we've received your payment, you will get a notification email from us containing a link to your order summary.
You will get an email with your invoice as soon as we shipped your 3D printout.
If your 3D printout is broken, or if you even got a bag full of powder, then it's likely that your 3D model had some deficiencies. We are very careful with packing and shipping your objects. Please read our design guidelines to avoid a situation like this.

We support the following file formats: ply, stl, 3ds, 3mf.
Minimum Wall Thickness: 1 mm
Minimum Clearance: 1.0 mm
Minimum Escape Holes: 10.0 mm
For more information, please read our Design Guidelines for 3D Models.
When you are adding up the Width (W), Depth (D), and Height (H) of your model, it should not be larger than 360 mm. W + D + H ≤ 360 mm
Wall thickness means the distance between the inner surface and the corresponding outer surface of an object. Walls should be at least 1 mm thick. If they are thinner, the model can brake more easily.
The clearance between two parts of the model should be at least 1.0 mm, otherwise your parts could get melted together at this spot. That happens mostly when you create movable parts.
The minimal diameter of holes and cavities in the model should be at least 1.5 mm, otherwise holes will not be visible and melt together as one surface.
When designing hollow models, don't forget to create escape holes. These holes are necessary to get rid of the unused Polyamide 12 powder. If you forget them, this powder would be enclosed in your 3D printout and that's rather uncool. If you just use one escape hole, be sure to make it at least 10.0 mm wide.
If you design embossed fonts or similar little details, you probably want to see them on your 3D printout as well. Be sure to design these details with both a height and width of at least 0.7 mm, otherwise your details could get melted together and you won't be able to recognize them.
If you use long and thin parts in your model, then these parts could be affected by warping due to high differences in temperature induced by the laser. To avoid warping, you could make the according walls thicker or you could add supporting struts.
If you design two parts that are engaging with one another, like gear wheels, be sure to have enough distance between them, since you don't want them to be melted together by the laser. In General, a distance between 0.5 mm and 1 mm or more is ideal.
Related question: What is the minimal clearance?
Inverted normal, unconnected edges, free-floating triangles and a lot of tiny holes: these are probably the most common mistakes in 3D modelling. You can try to use free software like Netfabb or the trinckle 3D online repair service to repair your 3D models.
Your model needs logical inner and outer sides. It should have a closed surface without any holes and no free-floating edges or triangles. You should use Boolean operators to connect different parts of your model, otherwise you could get a bag of Polyamide 12 powder instead of a nice printout. And nobody would want that, right?
