LMD project data
Laser metal deposition in numbers: what LMD delivers in real projects
Across 20 published projects, Exafuse has used laser metal deposition (LMD) to apply layers from about 1.5 mm to 20 mm, build parts weighing over 150 kg and repair a spindle within 24 hours. The table links each publicly documented figure to its project context.
