Before you design a 3D printed mold, it is important to consider the boundaries. With our current material and process the mold is best used for low to medium series production at low pressure (1 bar pressure difference) and low temperatures (up to 100C mould temperature). We achieve a tolerance of 2 mm and surface roughness of 250 µm with our 3D printing process.
If a 3D model is used as a mold, typically a polished or coated surface is recommended, which you can indicate during the ordering process.
It is advised to use standard agents on your moulds. However, we strongly advise to test your standard agents first on a small surface of your mold. PVA or a release film can be used to ensure the maximum usage quantity.
We can print 3D models with a size of 0.5 x 0.5 x 1 meter. However, we can combine multiple 3D prints to form a larger mold. Generally, we would say that our molds are an option to investigate for products larger than 10 cm and smaller than 3m.
A 3D printed mold is efficient when the number of demolding is moderate to low and tolerance requirements are not to stringent. It is the perfect tool for a first production run or a small customised batch.
