“…Since, in previously published research, other printer models were used, the results cannot be compared directly. On a qualitative basis, generally similar trends are reported for the factors tested, even though not always statistically significant [6,15,38]. It is also important to note that the mechanical properties of photo-polymers are time dependent.…”

“…It is also important to note that the mechanical properties of photo-polymers are time dependent. Since they change linearly [38], tests undertaken in constant conditions remain comparable and the results can be generalized.…”

“…To have the same surface finish for all sides, the 'mat' option of the printer is used, covering all surfaces in support material regardless of the actual need. This also prevents overcuring due to increased UV exposure [38]. Unless otherwise stated, the support material is mechanically removed from the parts.…”

“…The geometric accuracy of parts printed on the same model was investigated by Singh [14]. Blanco, Fernandez and Noriega [38] looked into the effect of part orientation on the relaxation modulus of parts printed in an Objet30 desktop printer. Scale factors, which needed to be accounted for manually on older models like the Objet Eden 330, were optimized by Brajlih, Drstvensek, Kovacic and Balic [16].…”

“…The effect of build direction/orientation in the PolyJet process has been studied previously in respect to tensile stress [8,[10][11][12][13], surface roughness [8,14], hardness [13], viscoelasticity [15], and thermomechanical properties [16]. This paper investigates the effect of build orientation on dimensional accuracy and surface finish of a given part using a commercially available PolyJet based printer, the Objet 260 Connex1 from …”

With advances in additive manufacturing, particularly in the area of three dimensional (3D) printing, it is becoming possible to generate small quantities of functional components. As with all manufacturing technologies, the ability to reproducibly generate parts with defined dimensional accuracy and surface finish is of key importance. This work characterises the ability of one such technology, PolyJet 3D printing, to produce such parts. In order to characterise the output from the manufacturing technique, a test part was designed and manufactured in three alternative materials representative of alternative grades across a commercial range. The designed test part consisted of positive and negative feature types printed both in the direction of, and normal to, the print head traverse direction. The test parts were characterised in terms of dimensional accuracy in three dimensions and also in terms of surface finish. Differences in dimensional accuracy and surface profile were observed depending on the orientation of the feature relative to the print head travel direction.

Mechanical properties of traditional engineering materials are typically coupled to each other, presenting a challenge to practitioners with multi‐dimensional material property requirements. In this work we demonstrate continuous, independent control over multiple mechanical properties in composite materials realized using additive manufacturing. For the first time, we experimentally characterize composites additively manufactured from rigid plastic, soft elastomer, and liquid constituents, demonstrating materials which span four orders of magnitude in modulus and two orders of magnitude in toughness. By forming analytical mappings between relative concentrations of constituents at the microscale and resulting macroscale material properties, we enable inverse material design; we showcase the method by printing artifacts with prescribed toughness and elasticity distributions. We place the properties of these composites in the context of biological tissues, showing they have promise as mechanically plausible tissue mimics.This article is protected by copyright.
