Additive manufacturing with vibration-isolating interface

An additive manufacturing platform comprising:

• a vibrating bed on which a volume of build material is to be disposed, which bed is to vibrate to remove excess non-fused build material;
• a non-vibrating frame to support the vibrating bed, wherein a portion of the vibrating bed rests on the non-vibrating frame;
• and
• a bed-frame connector to secure the vibrating bed to the non-vibrating frame, the bed-frame connector to:
• allow the vibrating bed to move in the horizontal plane when a vibration source is active;
• prevent the vibrating bed from moving in the horizontal plane when the vibration source is inactive;
• and
• prevent the vibrating bed from moving in the vertical direction;
• and
• a flexible seal between the vibrating bed and non-vibrating frame to:
• prevent build material contamination;
• and
• allow relative motion between the vibrating bed and the non-vibrating frame.

An additive manufacturing system comprising:

• a build material distributor to successively deposit layers of build material into a build area;
• at least one agent distributor including at least one fluid ejection device to selectively distribute fusing agent onto the layers of build material;
• and
• a platform that defines a build area, wherein the platform comprises:
• a vibrating bed on which a volume of build material is to be disposed, which bed vibrates to remove excess build material;
• a non-vibrating frame to support the vibrating bed;
• and
• a bed-frame interface comprising a fastener extending through the vibrating bed and non-vibrating frame to secure the vibrating bed to the non-vibrating frame, the fastener to:
• prevent vertical movement of the vibrating bed away from the non-vibrating bed frame;
• and
• permit the vibrating bed to slide horizontally over the non-vibrating frame during vibration of isolate vibrations to the vibrating bed;
• and
• a flexible seal between the vibrating bed and non-vibrating frame to:
• prevent build material contamination;
• and
• allow relative motion between the vibrating bed and the non-vibrating frame.
