Currently, it is possible to have applications using 4D printing, also known as shape-morphing systems, which uses 3D deposition, but the material is deformable; this is perfect for printing assemblies that include parts within others, impossible to obtain by traditional methods. However, it is necessary to point out that with technology, there are also low-cost alternatives, which in most cases it is advisable to verify the benefits considering the spare parts and technical support. There are technology tools that are open source, such as Cura® software, which is compatible with many low-cost 3D printing and control hardware that can be implemented in these printers, which means having modular and scalable systems.
Calibrating the 3D Printer
Published in Rafiq Noorani, 3D Printing, 2017
Filament settings do not change anything on the 3D printer; instead, it is useful and provide information to calculate how much a part would cost when being printed. This value is based on how much plastic filament the part takes to be made. Through communication settings, Cura communicates to the printer. The baudrate, which was also set in Marlin, can be adjusted here. It also includes the serial port which will be connected to the 3D printer. SD Card settings lends the choice of the location of the SD to save files autonomously. It can also show short file names on the display of the printer.

For each participant, three hand measurements were taken using a caliper: the palm width (second to fifth metacarpal head), the thickness (at the third metacarpal head), and the space between the index and thumb fold (see Figure 2). These were inserted into the online platform by the physician (MR). Then, the STL was downloaded and sent to the engineer (RT), who would proceed with the 3D printing on our institution’s 3D printer (Ultimaker S5, Ultimaker BV, The Netherlands, www.ultimaker.com). This is a dual extrusion high-end entry level fused deposition modeling machine. This type of machine works by extruding layers of melted material in a certain path on a build plate or on top of previously extruded material. An open-source software called Cura (Ultimaker Cura 4.11, Ultimaker BV, The Netherlands, www.ultimaker.com) was used for slicing (converting the STL to g-code for the 3D printing process). We used thermoplastic polyurethane (TPU95), a smooth rubber-like food, and dishwasher safe material, which is generally considered suited for objects involving skin contact.
Direct rapid prototyping from point cloud data without surface reconstruction

As shown in Tab. 2, the processing times range from 129 second to 402 second. With the traditional process, a CAD model needs to be created from point cloud data using software, such as ImageWare, or X design. Then, the CAD file will be refined and converted into STL model using modeling software, such as NX Siemens, or SolidWorks. Slicing software, like Cura, Slic3r, is required to slice the STL model and export G code for 3D printing. Such processes require professional knowledge and skills. Compared to the traditional process, the processing time using the direct 3D printing system is dramatically reduced.

The Windows 10 based desktop PC controls the 3D printer and CNC milling machine. The 3D printer control requires Cura open-source 3D printer slicing software. In Cura, 3D printing settings such as nozzle temperature, printing speed, layer height can be modified. The CNC milling machine control requires the Grbl Controller software sending ‘G-code’ to the machine. In the Grbl Controller, milling parameters such as feed speed and spindle speed can be changed.
