Dimensional error of selective laser sintering, three-dimensional printing and PolyJet models in the reproduction of mandibular anatomy.
J Craniomaxillofac Surg. 2009 Apr; 37(3):167-73.JC

Abstract

BACKGROUND

Selective laser sintering (SLS), three-dimensional printing (3DP) and PolyJet are rapid prototyping (RP) techniques to fabricate prototypes from virtual biomedical images. To be used in maxillofacial surgery, these models must accurately reproduce the craniofacial skeleton.

PURPOSE

To analyze the capacity of SLS, 3DP and PolyJet models to reproduce mandibular anatomy and their dimensional error.

MATERIAL

Dry mandible, helical CT images, SLS, 3DP and PolyJet prototypes, and digital electronic caliper.

METHODS

Helical CT images were acquired from a dry mandible (criterion standard) and manipulated with the InVesalius software. Prototypes were produced using SLS, 3DP and PolyJet techniques. Thirteen linear measurements of each prototype were made and compared with the dry mandible measurements.

RESULTS

The results showed a dimensional error of 1.79%, 3.14% and 2.14% for SLS, 3DP and PolyJet models, respectively. The models satisfactorily reproduced anatomic details and the SLS and PolyJet prototypes showed greater dimensional precision and reproduced mandibular anatomy more accurately than the 3DP model.

CONCLUSIONS

The SLS prototype had a greater dimensional accuracy than the PolyJet and 3DP models. The PolyJet technique reproduced anatomic details of the mandible more accurately.
