We have updated the Shapeways 3D Printing material page to make it easier to select the right material for your 3D Printing.
You can compare and select 3D Printing materials based on price, detail level, strength and smoothness so if you are new to 3D Printing it can help you find the right material for your needs and/or budget.
If you have a 3D model ready to 3D Print and you want to choose the right material you can enter the volume, surface area, thinnest walls or model size in bounding box to choose what 3D Printing materials can be used with your model.
This is especially handy if you know your model has very thin walls as it will let you know what materials are possible to reduce the chance of your 3D Print being rejected after upload.
This is another update as part of our recent refresh of the Shapeways experience.
