Enclosed vs. Open Frame 3D Printers: Which is Right for You?

When choosing a 3D printer, one of the first decisions you’ll need to make is whether to go with an enclosed or open frame design. Both have their pros and cons, and the best choice depends on your specific needs, environment, and level of experience. In this post, we’ll break down the key differences between these two types of 3D printers to help you make an informed decision.

Enclosed 3D Printers

Enclosed 3D printers have a built-in case or housing that surrounds the print area. This design offers several advantages:

  1. Temperature Control:
  • Consistent Environment: The enclosed design helps maintain a stable temperature around the print area, which is crucial for materials like ABS that are prone to warping.
  • Improved Print Quality: The consistent environment reduces the risk of drafts and temperature fluctuations that can negatively affect print quality.
  1. Safety:
  • Protection from Hot Components: An enclosure keeps users, especially children and pets, from accidentally touching hot components like the print bed or extruder.
  • Fume Containment: Some materials emit fumes when heated. An enclosed printer can be fitted with filters to reduce the release of these fumes into your workspace.
  1. Noise Reduction:
  • Quieter Operation: The enclosure helps dampen the sound of the printer in operation, making it a better choice for home or office environments where noise can be a concern.
  1. Aesthetic Appeal:
  • Clean Look: Enclosed printers often have a more polished appearance, which can be important if the printer is in a visible location.

However, enclosed printers also have some downsides:

  • Higher Cost: The additional materials and engineering involved in creating an enclosure can make these printers more expensive.
  • Limited Size Options: Enclosed printers often have a smaller build volume compared to open frame models because the enclosure limits the maximum size of the print bed and height.
  • Maintenance and Access: Accessing the print area for maintenance or adjustments can be more cumbersome with an enclosed printer.

Open Frame 3D Printers

Open frame 3D printers are designed without an enclosure, leaving the print area exposed. This design also has its own set of advantages:

  1. Affordability:
  • Lower Cost: Open frame printers tend to be less expensive than their enclosed counterparts, making them a great option for beginners or those on a budget.
  1. Accessibility:
  • Easy Access: Without an enclosure, it’s easier to monitor the print process, make adjustments on the fly, and perform maintenance.
  • Larger Build Volume: Open frame designs often allow for larger print areas, which is ideal for those who need to create big models or multiple parts in a single print run.
  1. Customization:
  • Modularity: Open frame printers are typically easier to modify and upgrade. Hobbyists who enjoy tinkering with their equipment often prefer this design.
  1. Cooling Efficiency:
  • Natural Ventilation: The lack of an enclosure allows for better natural cooling, which can be beneficial for printing with certain materials that don’t require a controlled environment.

Despite these benefits, open frame printers have their limitations:

  • Environmental Sensitivity: Open frame printers are more susceptible to drafts and temperature fluctuations, which can negatively impact print quality, especially with certain materials.
  • Safety Concerns: The exposed hot components pose a safety risk, particularly in environments with children or pets.
  • Noise Levels: Without an enclosure, these printers can be noisier, which might be disruptive in a shared space.
  • Aesthetic Impact: Open frame printers may look more industrial or DIY, which might not be ideal for all settings.

Which Should You Choose?

Choosing between an enclosed and an open frame 3D printer boils down to your specific needs:

  • Go for an enclosed printer if you:
  • Plan to print with materials that require a stable temperature, like ABS or Nylon.
  • Want a quieter, safer, and more aesthetically pleasing printer.
  • Need to control fumes or protect the print area from environmental factors.
  • Opt for an open frame printer if you:
  • Are looking for a more affordable option or have a limited budget.
  • Value easy access to the print area for adjustments and maintenance.
  • Want the flexibility to print larger models or modify your printer.

In the end, both types of printers can produce high-quality prints, but your decision should be guided by your specific needs, budget, and environment. If you’re just starting out and are unsure, you might start with an open frame printer and upgrade to an enclosed model as you gain more experience and refine your printing requirements. Those of you who are avid printers know there is more to this discussion than we covered here today. These things will be discussed in further detail down the road.
