# Tetra Pak, DTI and AMT: 3D printing in ice cream production

Tetra Pak set out to develop an ice cream extruder that mixes several colors of ice cream and places them on a production line in a variety of shapes and patterns. Its previous extruder had sanitization and efficiency issues, so Tetra Pak turned to the Danish Technological Institute (DTI) and AMT PostPro.

## The result

With AMT PostPro vapor smoothing, Tetra Pak achieved:[PDF](https://6983077.fs1.hubspotusercontent-na1.net/hubfs/6983077/Website/Case%20Studies/AMT_CS_DTI_FOOD_CONTACT_ICE_CREAM_EXTRUDER.pdf?ver=2)

- A 60% cost reduction
- A delivery time cut in half
- Part consolidation from 30 parts to 3
- Significantly increased hygiene[PDF](https://6983077.fs1.hubspotusercontent-na1.net/hubfs/6983077/Website/Case%20Studies/AMT_CS_DTI_FOOD_CONTACT_ICE_CREAM_EXTRUDER.pdf?ver=2)

The case study also notes that 3D printing for food applications is faster and significantly cheaper than previous manufacturing methods.

Results

- −60% cost
- ½ the delivery time
- 30 → 3 parts, consolidated
