InstructMesh edits the intermediate latent representation to open or seal voids and adjust local thickness without requiring expert modeling tools. Two user studies found that novices could identify and repair fabrication-relevant failures and preferred a hybrid of slider controls and natural-language input; the work evaluates repair assistance, not guaranteed printability.",
