En el mundo de la tecnología de impresión 3D, El volumen de compilación es un concepto central que define el tamaño físico máximo que una impresora 3D puede producir. This article will take you through the importance of build volume and its application in 3D printing, for consumers to refer to when making purchases.
What is Build Volume?
Build Volume refers to the maximum physical size that a 3D printer can produce in a single print job, usually defined by three measurement values: width (X-axis), depth (Y-axis), and height (Eje Z). En breve, Build Volume is the “workspace” of a 3D printer.
Popular explanation:
Comparing a 3D printer to a magic box, the build volume is the size of the largest toy that can be manufactured in one go. If the toy is larger than the box, it needs to be manufactured in blocks before assembly.
The importance of a build volume lies in the fact that it determines the size of the objects that can be created at once . For industries such as automotive, aeroespacial, and healthcare, a larger build volume allows for the production of larger, more complex parts without assembly, which can save time and improve the structural integrity of the final product. A build volume is critical to choosing the right 3D printer. It not only limits the size of the objects that can be printed, but also affects the efficiency and cost of printing. Por ejemplo, a large build volume allows for larger parts to be printed at once, reducing the need for assembly, but may also mean higher material consumption and longer printing times.
Nota:
Generalmente hablando, the larger the size of the printer, the higher its purchase cost and required material cost. Además, large printing tasks not only take longer, but also have a greater risk of failure during the printing process. Por lo tanto, although a large build volume is very valuable for specific application scenarios, it does not mean that it is necessary or suitable for all projects.
Practical Application
When exploring the limitations of different 3D printing technologies on build volume, we can start with three mainstream technologies: MDF (fused deposition modeling), SLA (stereo light curing), and SLS (selective laser sintering), and analyze their differences in build volume.
MDF (Modelado por deposición fundida)
FDM technology uses thermoplastic materials to build objects by melting and stacking them layer by layer through a heated nozzle. The advantage of this technology is that the operating environment is clean and safe, the material is non-toxic, and it is suitable for use in office and home environments. Sin embargo, the build volume of FDM technology is relatively small , and the build volume of desktop or vertical 3D printers is usually up to 300 X 300 x 600mm. Además, parts printed by FDM often have visible layer lines, rough surfaces, and require subsequent polishing.
SLA (Stereo Light Curing)
SLA technology uses liquid photosensitive resin to construct objects by curing the resin layer by layer with a UV laser beam. SLA technology can achieve excellent surface quality and 50 micron resolution, suitable for manufacturing small castings and molds. The build volume of SLA is usually limited The build volume of desktop or vertical 3D printers is up to 300 X 335 x 200mm. SLA technology has difficulties in handling large parts, and some resins require additional post-curing.
SLS (Sinterización por láser selectiva)
SLS technology uses high-power lasers to fuse small particles of plastic, metal, cerámica, or composites into solid objects. Unlike FDM, SLS does not require support structures because the powder acts as its own support material. SLS technology can produce complex parts with moving internal features, and the finished parts have smooth surfaces comparable to injection-molded plastics. SLS has a relatively large build volume , with industrial-grade vertical 3D printers having a build volume of up to 165 X 165 x 300 mm. Sin embargo, SLS printers are more expensive and have slower printing speeds.
Conclusión
Building volume is an indispensable concept in 3D printing, which affects the possibility, eficiencia, and cost of printing. With the development of technology, we can foresee that building volume will no longer be a limitation, but the starting point of 3D printing innovation. Understanding building volume is crucial for choosing the right 3D printing technology, optimizing the printing process, and exploring new application areas.
