Want to test our material before you order?

Before you place your order, if you want to be 100% sure that our material is suitable for your project, why not order one of our sample packs?

It contains examples of our four finishing choices, three unique parts designed to demonstrate the potential of printing in SLS nylon and a 20 page brochure containing information on our material, our services and tips on how to save money with your prints.

Welcome to our new faster Manual Upload v2.1

We’re sure you’ll like our new system – its much faster, smoother and vastly more functional version than our old one. You are able to add multiple files at the same time, you’re able to select each finishing option and quantities and save different versions of the quote to suit your needs, and able to check out whenever you want day or night. There is no maximum filesize.


You will be emailed a quote – please check your junk mail if it has not arrived within 15 minutes during working hours!

If the upload function does not work for you then please send them to us securely via WeTransfer. Use stl@3dprint-uk.co.uk as the ‘Friends Email’. This will be pre-filled if you use the link below.

Sometimes, you just need to hold an object to know if it’s right for your prototype or production run, especially if your ordering 100’s if not 1000’s of parts. Our sample pack has been designed to answer those questions, it contains examples of the four finishing choices we offer and three specific parts that demonstrate the huge possibilities of sls printing. There is also a 20 page booklet introducing all of our services, how to save money with your prints and technical data about the process.

3DPRINTUK don’t make any money from our sample boxes, we absorb the cost of the parts but ask you to cover the postage. The idea is to help you feel confident that you’re making the right decision for your order.

We look forward to working with you and if you would like to order our sample box please visit our sample box page and fill out the form.

Why is my model so expensive?

There are a few possibilities as to why your model is expensive when quoted.

Large things – volume is key. We are charging on the bounding box around the model and a large model has a large bounding box. It’s just the nature of 3D printing that large parts will be expensive.

We have a minimum part charge which may apply to small parts on smaller orders. The minimum part charge is to cover the cleaning process as it’s very time consuming to hand clean very small things with a high pressure air gun. To avoid this charge check our guides on spruing and sinter boxes.

If you are using the automatic uploader it may be that your model has ‘noise shells’ counting as bodies each being charged at £2. If the dimensions of your file are pretty small and you’re being quoted a big round figure that’s a multiple of 2 try the manual upload where we can check and fix your file before quoting.

The process. We are using the Selective Laser Sintering (SLS) process using large industrial machines. There are cheaper alternatives but they produce different results.

Are there discounts for students?

Yes, we do offer a discount to students. Read more about it here.


You will need to upload using a valid student email address on the Manual Upload.

Are there discounts for low volume manufacture/batch production runs?

Why won't my model upload to the automatic system?

There is a maximum filesize of 25mb so do check that your file isn’t edging towards that.


Files that are too long/big will not be accepted either. The maximum dimensions are currently 300mm x 230mm x 190mm. If your file is larger than this it may still be possible for us to print it so please try the Manual Upload and we can advise on what’s best to do.

How can I view my model/check my model is the right scale?

You have two easy options. You can either upload your file on our Automatic Upload which will give you a visualisation and will display the dimensions of your part in the top right of the visualisation box.

Alternatively you can download a free STL viewer. Netfabb Basic is totally free and does the job perfectly.
