The advent of 3D printing technologies has enabled scientists to design and create complex, customized devices for use in experimental settings. Many companies have developed plug-and-play 3D printers with remarkable precision and accuracy. However, the adoption of these technologies in the field of neuroscience has been comparatively slow. This webinar provides an introduction to the world of 3D printing, offering neuroscientists a clear path to incorporating this technology into their research.
Speaker
Meredith L. (Jones) Shand
This webinar presented by Curtis Neveu, PhD, provided an overview of how 3D printing can be integrated into a wide range of neuroscience research. Neveu began by describing the role of 3D printing within additive and subtractive manufacturing and highlighted how additive methods enable the creation of customized research tools. He continued by covering key advantages of 3D printing, including cost savings, customization, and the use of relatively inexpensive materials. Neveu then discussed limitations of the technology, noting that successful printing often involves significant trial and error.
Neveu reviewed current 3D printing applications in neuroscience, ranging from building mechanical devices to advanced techniques such as two-photon printing for producing microscopic components. He introduced computer-aided design (CAD) as an essential component for a successful print. Several CAD programs were highlighted, including free options such as SketchUp, Blender, and FreeCAD, as well as the industry-standard software SolidWorks. Neveu also provided an overview of common 3D printing methods—fused deposition modeling (FDM), stereolithography (SLA), and selective laser sintering (SLS)— and outlined how each method may be suited to different research needs.
The session concluded with practical tips for improving print quality and troubleshooting common issues, such as uneven layers, holes, stringing, and melting. Environmental factors like humidity were discussed alongside design strategies such as minimizing support structures, using high infill when feasible, and ensuring proper build plate adhesion.
Although 3D printing may feel intimidating to many biological scientists, Neveu made the technology more accessible through clear explanations and practical examples. For instance, researchers can print custom holders for vibratome slicing, or design brain matrices for sectioning at highly specific angles. Additionally, 3D printing offers a cost-effective avenue for custom rodent implants that facilitate imaging experiments. Overall, this webinar provided an accessible introduction to the range of 3D printing techniques and highlighted practical strategies for integrating this technology into neuroscience research, particularly in histological and optogenetic applications.
