As a designer on Shapeways, you have the ability to make your unique ideas truly come to life. As a shop owner, you are able to share those designs with the world. And what's more, you can make these products as personal and customizable as you'd like.
Right now, there are technically 2 options for customization available to you on Shapeways as a designer. You can add CustomMaker to most models, or you can manually customize products for customers. You'll find these options on the Details tab of your product.
CustomMaker gives shoppers the ability to personalize their favorite products in your shop. Add text or image "regions" to your model, but leave the details up to the customer! Learn more here.
Manually by Me
Manual customization is available for designers who want to offer more options. Things like different sizes, fonts, etc are all examples of "Labels" you can choose to offer to customers. Note that this requires a bit of communication with the customer, as well as a constant watch on your Shapeways shop/email to monitor orders. You do have the ability to note an "Out of Office" time on your Shop Settings page, but can also turn off this option by product at any time.
