RGD450+TangoPlus is an advanced rubber-like material that can be printed with a smooth surface by ENNOIA Company (Besançon, France) using the Connex3TM Object500 3D printer (Stratasys Ltd.©, Israel). It is a composite material of RGD450 and TangoPlus (Stratasys Ltd.©, Israel). Materials of different shore hardness were printed and tested (Table 1 ). Although the size of the printed RGD450+TangoPlus specimens was 40 mm × 40 mm, the size of the tested RGD450+TangoPlus specimens was only 15 mm × 15 mm. Figure 2 shows the printed RGD450+TangoPlus specimens. The tested specimens maintained directional consistency during testing. The direction was fixed according to the biaxial test system and was defined as A and B.

The CAD models were translated to the printer in a printable Standard Tessellation Language (STL) format. First, the STLs of the 11 cubic samples (C00–C100) were transferred to the PolyJetTM printer Connex3 Objet500 (Stratasys Ltd., EdenPrairie, MN, USA). Then, 11-cubes in sets of two were printed, each set with a different material for the grid structure: solid bio-compatible MED610 (Stratasys, EdenPrairie, MN, USA) with a Shore hardness of 83-86 (Scale D) and flexible TangoPlus (Stratasys Ltd., EdenPrairie, MN, USA) with rubber-like properties with a Shore hardness of 26-28 (Scale A). SUP706 (Stratasys Ltd., Eden Prairie, MN) was chosen as the support material. The samples were printed with different matrix thicknesses as designed in the CAD software, yielding a specific partial volume contribution C% of the MRI-signal generating material to the voxel.
The spherical tumour models were printed using a different material for the grid structure, TangoPlus, VeroClear and VeroMagenta (Stratasys Ltd.). The general properties of VeroClear and VeroMagenta were similar to those of MED610 but not approved biocompatible. The same support material as for the cubic samples, SUP706, was used.

Two methods and four materials were used to fabricate the soft actuators. Two methods are: (1) the traditional casting process, (2) 3D printing using the Objet350 Connex3 printer (Stratasys, Minnesota, USA) and the Agilista printer (Keyence, Japan). Four materials are: (1) the Dragon Skin 10 (Smooth-on Inc., PA, USA), (2) the Ecoflex (Smooth-on Inc., PA, USA), (3) the TangoPlus or TangoBlackPlus (Stratasys, MN, USA), which mainly consists of propenoic acid, ethyl ester, and trimethylbicyclo, and has a hardness of Shore A26-A28 and an elongation at break of 170–220%, and (4) the AR-G1L (Keyence, Japan), which mainly consists of silicone and acrylate monomer, and has a hardness of Shore A35 and an elongation at break of 160%.

The .STL file of the final digital dataset was delivered electronically to the Laboratory of Rapid Prototyping at the University of Strathclyde, Glasgow, where the 3D printing was carried out using the Object Eden 350V printer (Stratasys, Rehovot, Israel). Two materials were used for manufacture. The models of the biliary tree with gallbladder and the hepatic artery were manufactured using TangoPlus (Stratasys, Rehovot, Israel), and the models representing the hepatic veins, liver tumour and the portal vein were printed using TangoBlack (Stratasys, Rehovot, Israel). Each structure was printed en-bloc, surrounded by a gel-like support structure to protect overhanging parts of the model during the printing process (Figure 3). Once printed, the models underwent post-manufacture processing which included removal of the support structures with pressured water jet, and painting.

Polyjet printing is a technology that is capable of fabricating complex multimaterial geometries by jetting and curing various photopolymer68 (link). We used two commercially available soft photopolymers (i.e., Agilus and TangoPlus) and a rigid photopolymer to fabricate viscoelastic kirigami using a commercial 3D printer (Objet500 Connex3, Stratasys, see Supplementary Information section A, B and C) . To reach an effective strain rate and achieve high-speed mode of buckling, we developed a costume-made test bench with a low-friction Teflon substrate allowing us to adjust the speed of stretch in the range of 1 to 5000 mm/s. We then analyzed our experiments by tracking the embedded particles (i.e., black dots and monochrome patterns) on the surface of kirigams using Matlab codes and analyzed the snap-back of kirigami unit cells in 3D using a Python code (see Supplementary Information section D) .

The head of an Alderson Rando phantom (The Phantom Laboratory, Salem, NY, USA) was utilized for the fabrication process. Because the phantom is dark in colour, powder spray was applied to obtain a better resolution and 3D image accuracy. Next, the optical image data of the phantom were acquired with the use of an Artec Spider 3D scanner (Artec Group, Luxembourg) and exported to the workstation. The surface image data were reconstructed, and a customized 3D bolus was designed with the Geomagic Design X version 2014 software package (Geomagic Inc., Morrisville, NC, USA). A 5-mm-thick customized bolus of the nose was designed by isotropic expansion from the surface.
The designed bolus was printed with the use of a Stratasys Objet500 Connex3 with the use of PolyJet technology (Stratasys Ltd., Eden Prairie, MN, USA) with the malleable ‘rubber-like’ printing material, Tango Plus (Stratasys Ltd.), to reduce patient discomfort and unwanted air gaps.Fig 1 shows the overall processes involved in the bolus fabrication.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
