VPI - JMW 12 3D Tonearm
			
 
			
The arm looks like a traditional VPI Unipivot arm, except it's made in a 3D printer. The material is basically epoxy, which forms a rigid, lightweight, structure with good insulation properties. Epoxy is non-crystalline which impedes the transfer of vibration, so it’s the perfect material for tone arms. The shape of the tone arm shaft also adds rigidity to the structure and further prevents the transmission of surface vibrations. The result is a low resonance lightweight tone arm.
