First, the Autodesk Inventor software (Autodesk Inc., San Rafael, CA, USA) was used to draw 3Dpictures of the test specimens. Since most slicing software accepts .stl files and .obj files, the Inventor files were converted to .stl format. Then the file was delivered to the slicing software for parameter adjusting. KiSSlicer was used as the slicing software. The experimental factors of the slicing software were categorized into control factors and fixed factors. The fixed factors included printing speed of 37.5 mm/s, platform temperature of 60 °C and the rectilinear type of filling pattern. The raster angle of 45°/45° was chosen, as shown in Figure 1 . The controlling factors included filling percentages of 10%, 20%, 33.3%, and 50%, and printing nozzle temperatures of 185 °C, 195 °C, 205 °C, 215 °C, and 225 °C. To minimize the effect on the results of the experiment, this experiment was mainly based on the parameters set by the slicing software, as shown in Table 3 . The quality of a 3D-printed object depends on the quality of the initial 3D model of the object; therefore, the image acquisition step was essential for the quality of a 3D-printed object. The three different requirements of printing quality were: (i) low surface roughness, (ii) good mechanical properties, and (iii) short printing time. This study discusses the mechanical properties of printing quality.

Ultralight Ultrasonic Probe for Mouse Studies

The challenge for awake and mobile experiments in the mouse is its small size compared with rats. Our setup consists of a new ultralight ultrasonic probe (described above) mounted in a magnetic probe holder, and a metal frame fixed on the mouse head (Fig. 1 a,b). All these elements have been designed to minimize size and weight. The metal frame fixed directly on the skull of the mouse (Fig. 1c1 ) is a rectangle (12 × 23 mm) with an imaging window (6 × 21 mm), cut from a galvanized steel plate, a magnetic material. This property is used for rapid clip-on fixation of the probe holder to the metal frame. For this purpose, four small but strong magnets (Supermagnete, Gottmadingen, Germany, Q-05-1.5-01-N, 1 × 1.5 × 5 mm, NdFeB, adhesive force: 140 g) were built into the base of the probe holder (Fig. 1 a), enabling magnetic fixation between the metal frame and the probe holder (Fig. 1 b). The probe holder was designed in Autodesk Inventor software (Autodesk, Inc., San Rafael, CA, USA) and made by a 3-D printer (MakerBot, New York, NY, USA).

The layout of the device was designed by Autodesk Inventor Software (version 2021.2.1, Autodesk, CA, USA). The device enclosure was designed to be attached to the skin around the user’s wrist similar to a regular watch. The enclosure was designed to use every space effectively with the size of 37 mm × 63 mm × 30 mm (displayed in an inset of Figure 1 a).
The 3D-printer and Ultimaker Cura software (version 4.12, Ultimaker, Utrecht, The Netherlands) were used to construct the device (Autodesk layout displayed inFigure 1 e) from the PETG filament and then attached to the commercial nylon watch bands.

Geometric models of test specimens necessary to perform tests have been made according to ISO 527-2-1A (Overall length = 170 mm) and ISO 179-1 (80 × 10 × 4 mm, unnotched Charpy) standards with AUTODESK Inventor software (Inventor: 2018.3 Build: 284, Autodesk, Inc., San Rafael, CA, USA). Preparation of samples for 3D printing manufacturing purposes required making small corrections in specimen models by increasing thickness by 0.15 mm, which corresponds with the thickness of the first layer used to attach the print to the printing table.

Modelling Stirred Tank Reactor Electrocoagulation

The modelling of the stirred tank reactor was conducted in steps. First, the modelling was carried out using the numerical Computational Fluid Dynamics (CFD) analysis of fluid flow during the electrocoagulation process. The purpose of this step was to estimate the physical behavior of fluid flow using numerical methods. The Rocky program was applied to simulate the aggregation of molecules carried by hydroxides onto the liquid surface. Next, the geometry of the mixer, fluid capacity, and baffles in the form of electrodes were modelled as separate regions using Autodesk Inventor software. Next, these geometries were imported into the ANSYS Fluent environment (ANSYS Inc., Canonsburg, PA, USA) to perform preprocessing and discretization. Complex interfaces between contact fluid fields and boundary conditions were made directly in the ANSYS software geometric module. The mesh was generated in order to discretize the computational domain for small control capacities, where basic fluid mechanics equations were approximated with numerical computing.

The multilayer microfluidic device was designed by using Inventor software (Autodesk, München, Germany). The device featured: one PDMS (Sylgard 184, Dow Corning Corp., Midland, MI) microchannel layer that was plasma bonded (PDC‐002, Harrick Plasma, New York, USA) to a 1.5# glass coverslip, which had been patterned with ITO electrodes (glass–ITO, 30–60 Ω, Diamond Coatings, West Midlands, UK); a semipermeable PET membrane with a pore size of 0.4 µm and a thickness of 12 µm (it4ip, Louvain‐la‐Neuve, Belgium); one PDMS interlayer; a platinum‐patterned PET (Sigma‐Aldrich, Buchs, Switzerland) electrode layer; a PDMS hanging‐drop and medium‐reservoir layer. As it is difficult to completely remove the hydrogel and cells from the microfluidic channel and brain compartment, this study opted for disposing off the devices after use. Detailed information on the platform fabrication and assembly is reported in the Supporting Information.

To produce
the MESIF chip, a casting mold corresponding to the housing structure
was designed using Autodesk Inventor software (Figure S2E ) and milled on a poly(methyl methacrylate) (PMMA)
plate using a CNC micromilling machine. To cast the housing structure,
PDMS prepolymer was prepared as described above and poured into the
chip mold and then cured at 70 °C for 1 h in the oven. After
curing, the cast was peeled off the mold and was ready to fit the
MESIF material pieces inside (Figure S2F ). Likewise, a mold for the chip cover lid (76 × 26 × 0.75
mm3) was prepared using the same procedure into which the
holes (ø 4 mm) for the environmental contacts were manually inserted
with a press puncher.
For assembling the MESIF chip, the prepared
three components (MESIF piece, PDMS housing, and lid) were individually
activated by plasma treatment (Plasma Flecto10, PlasmaTechnology)
for 30 s at 300 W and 0.2 mbar. Then, the MESIF piece was placed in
the corresponding empty space in the PDMS housing, covered with the
PDMS lid (Figure S2H ) and the assembled
chip was cured at 90 °C for 30 min for permanent bonding.

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.
