Paving machine

Tiger-Stone is a Dutch made paving machine that uses gravity and an electric motor to print stone and brick roads. It’s a six meter wide machine that is capable of laying 300 square meters of road a day. The printing width is adjustable from the width of a road to as narrow as a bike lane or walkway. There are no moving parts within the machine, it simply uses a shelf that is fed bricks and they are automatically sorted and packed together by gravity, each stone will associate with the link previously made. There is a quiet electric motor that moves the machine along a bed of sand creating consistent results with a simply operated paver.
