Open-Source 3D Printed Diffusion MRI Phantoms

Check if the same lab product or an alternative is used in the 5 most similar protocols

An open protocol for producing 3AM phantoms has been developed and released as part of an Open Science Framework project (available in the Supporting Information and hosted at osf.io/zrsp6). Required materials include an FDM 3D printer, a dual‐component “porous filament” material, a vacuum chamber, and a set of watertight containers. The protocol was used to produce all phantoms for this study.
All phantoms were designed using the open‐source Ultimaker Cura software and were printed with an Ultimaker 3 Extended 3D printer (Ultimaker, Geldermalsen, the Netherlands) loaded with GEL‐LAY filament. Unless otherwise noted, phantoms were printed with printing parameters recommended by the material vendor (Table 1), and the same pattern of parallel lines of material in each layer.
After printing, phantoms to undergo dMRI scanning were immersed in 1 L of room‐temperature tap water (~23°C) for 168 hours, then 20 mL of surfactant was added to decrease surface tension and allow the water to more easily enter the pores. The container was placed in a vacuum chamber at 1 bar for 48 hours to remove air bubbles. Finally, the phantoms were stacked in a test tube with distilled water for imaging (Figure 1C,D). Phantoms that undergo dMRI are kept in water at all times after preparation.

3D Printing Kidney Phantom Models

Check if the same lab product or an alternative is used in the 5 most similar protocols

The resulting models were printed using the Ultimaker 3 Extended 3D printer (Ultimaker B.V., Utrecht, Netherlands), a fused deposition modelling (FDM) printer capable of dual-extrusion. Polylactic acid (PLA) was used to print the phantom walls, and polyvinyl alcohol (PVA) was used as a water-soluble support. To reduce print times and the amount of required support material, all kidney models were divided into two halves, as shown in Fig. 2D. After printing, the PVA support structures were removed by repeated rinsing with water. After drying, the matching halves were glued together. If necessary, phantoms were sealed by coating with epoxy resin to prevent leakage of the filled phantom.

3D Printed PLA Vascular Stents with NPR

Check if the same lab product or an alternative is used in the 5 most similar protocols

The PLA vascular stents with NPR structure were prepared by Ultimaker 3 Extended FDM 3D printer (Ultimaker B.V., Geldermalsen, Netherlands). The Ultimaker 3 Extended 3D printer has a dual extrusion system, which can print two different materials. The nozzle 1 prints the natural PLA material, and the nozzle 2 prints the water-soluble support material Polyvinyl Alcohol (PVA). After printing, soaking the three-dimensional solid in water will remove the support materials and leave the required three-dimensional solid products. The 3D printing filaments of PLA and PVA were purchased from Esun (Shenzhen Esun Industrial Co., Ltd., Shenzhen, China). The natural PLA is colorless and slightly transparent and has the density of 1.24 g/cm³, the melting index of 5 g/10 min (190 °C/2.16 kg), the tensile strength of 65 MPa, the elongation at break of 8%, the bending strength of 97 MPa, the flexural modulus of 3.6 GPa, the impact strength of 4 kJ/m². PVA is soluble in water and has the density of 1.25 g/cm³, the tensile strength of 22 MPa, the elongation at break of 360%.

Ni-NiO Particle Compact Fabrication

Check if the same lab product or an alternative is used in the 5 most similar protocols

The starting material for the particle compact in all cases was a physical mixture of nickel oxide (Sigma Aldrich, 44 µm, 99% purity) and the activated nickel metal particles ground together briefly (ca. 5 min) using a mortar and pestle. Several weight ratios of the metal/metal oxide were tested. Also controls, that employed a different protocol, described in the Results section, were performed. None of the control protocols created Ni metal, self-supporting objects.
In one example a roughly ‘rectangular’ compact, 3 cm × 1 cm × 2 mm deep, was created by hand shaping a 1:1 weight mix of Ni:NiO. The shape was formed on top of a section of perforated Grafoil (4 cm × 2 cm) ‘support’ (Figure 1). In other cases a tensile specimen, with the dimensions ratios employed for the ASTM International standard flat ‘dog bone’, compact roughly 3 cm long was created by filling a mold produced using a standard desktop 3D printer (Ultimaker 3 Extended 3D printer, using 3 mm PLA filament, Ultimaker B.V., Utrecht, Netherlands), positioned on top of a perforated 0.3 mm thick Grafoil, a ‘paper consistency’ material composed (99.9%) of compressed Graphite flakes with a surface area of 22 m²/gm [13 (link),14 (link)]. Before firing, the mold was removed, yet the shape was retained with no binding agent.

3D-Printed Hemipelvis Model for SCFE Deformity Correction

Check if the same lab product or an alternative is used in the 5 most similar protocols

A 3D-printed model of hemipelvis was generated using a CT scan of a patient with chronic SCFE deformity (Fig. 2). CT scan was obtained from the Hospital Medical Imaging Department server as an anonymized digital imaging and communications in medicine (DICOM) file. The DICOM file was imported into the 3D Slicer software [The Slicer community, Boston, MA, USA]. Segmentation was completed with an automated thresholding protocol within the software to isolate the skeletal element of the hemipelvis and proximal femur. A printable Standard Tessellation Language (STL) file was exported from 3D Slicer and 3D printing was carried out using the Ultimaker Cura program and the Ultimaker 3 Extended 3D printer [Ultimaker B.V., Utrecht, Netherlands]. The 3D model was printed with the factory standard printing protocol using Ultimaker PLA (polylactic acid) filament.
To confirm the degree of achievable correction with our described surgical technique, the 3D model was used by the senior surgeons to plan the osteotomy cuts and deformity corrections illustrated in Fig. 3.

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.
