<p>Current micro-tunneling projects are often costly due to high material and labour expenses, making smaller projects economically unfeasible. Conventional HDD and microtunneling methods also cause noise, vibration, and ground settlement, raising safety and environmental concerns, particularly in densely populated areas. Furthermore, many regions feature changing ground conditions that conventional machines struggle with. SLT, a student association, introduced the Groundhog prototype series: a fully autonomous boring machine that prints the tunnel's inner wall using thermoplastic extrusion. This solution significantly cuts costs, reduces ground settlement, and is adaptable to varying ground conditions. It is poised to tap into a multi-billion-dollar market, addressing diverse global infrastructure needs.</p>
