R&D case: Enabling temperature control for large scale additive manufacturing
One of the main challenges of Large Scale 3D printing of high temperature thermoplastics is the control of the interface temperature – which determines the degree of bonding between consecutive layers. When the deposited material has cooled down in excess, poor adhesion is achieved between layers, leading to insufficient strength, delamination, cracking and part failure. If the material has not cooled down sufficiently, it won’t support the consecutive layers, therefore leading to print failure. The interface temperature control is especially important when attempting large scale prints and when processing semicrystalline thermoplastics.

NLR and Cryoworld collaborate on flying with liquid hydrogen
NLR is taking a further step towards more sustainable flight by partnering with Cryoworld to develop a liquid hydrogen tank. This follows the agreement with zepp.solutions for a fuel cell system. The new collaboration contributes to NLR's ambition to conduct a demonstration flight on liquid hydrogen in 2026.
