3D SCANNING AND PRINTING FAQ'S

Here's a list of some common question & answers

Let us answer some common questions you might have about 3D scanning and printing services.

3D Scanning FAQ's

Not sure if 3D scanning can help you?Not sure if you object is right for 3D scanning?

We’ve got some common FAQ’s that might help you decide. 

As we’ve said, we use structured light 3D scanning here at Surface Scan but it does come with a few limitations. Don’t worry though, we have ways of getting over most issues. 

Need more info? Check out our 3D scanning services page.

Maybe you already have the 3D scan data and need another service?

Here is a more detailed explanation on what is structured light scanning.

Lets say you wraped an object in clingfilm and it took the form of that shape and every tiny detail. You then remove the object without altering the clingfilm, your left with the exterior shape of your object, a mesh or point cloud. This data can then be used for various purposes.

Most files we send are in the format of an STL or an OBJ.

If we’ve reversed engineered your data it will normally be sent as either a STEP or IGES file.

generally we’ll send your data of secure servers or portable storage devices, whicever works best for you.

Absolutly, we offer a complete mobile service.

Yes, not a problem. Just bear in mind the postage costs and how big yor object is.

Scanning shiny or dark objects can be tricky for most 3D scanners. The way around this, is to spray the object with a non-reflective spray. Don’t worry though, it comes off. 

We use 3D scanners that scan using structured light. It basically projects a pattern onto the surface of the object and cameras data.

Have you handmade a prototype? Do you need to reverse an old mould? You want to create custom car parts? The list goes on, buy if you a problem and you need a solution, we’re here to help.

 

3D Printing FAQ's

Let us answer some of the questions people have when it comes to 3D printing. If we don’t cover all your questions, you might have then check out our 3D printing services page for more detail and to get your order started.

Our SLS 3D printing is a fantastic technology. It can print moving parts in one go, and there is no support structures needed. The parts are strong because of the way they are printed and the process they go through. 

All parts are printed with Nylon PA12.

Selective laser sintering or SLS uses lasers to fuse PA22 nylon powder together, it’s a bit like painting with lasers. We take your model, slice it with our software and build it up layer by layer.

You can save money with our 3D printing service by nesting your parts. What is nesting? 

Lets say you have a bowl and you printed that on it’s own, that’s not an issue, but what about all the space inside the bowl? Why not stack the 2 bowls together with a 1.5 mm gap or place another model that fits inside the bowl? That is nesting. Are prices are worked out by the square cm, not by the shape of the model.

We recommend a tolerance of around 0.2 mm for moving parts, any closer and you run the risk of the parts fusing together.

2 mm is around the right size.

1 mm wall thickness is good, but we can go down to 0.5 mm. The thinner your parts are designed, the greater the risk of your parts not printing.

Our current maximum print size is 300 mm.

In the Z axis it is + or – 0.075mm, in XY axis it is + or – 0.1 mm. These figures can change depending on the complexity of the model.
