Choosing between an enclosed vs open 3D printer is one of the first decisions users face when entering the world of FDM 3D printing. While the core printing technology may be the same, the frame style affects everything from material compatibility to print quality and long-term success.
Below, we explain how enclosed and open-frame printers compare, using practical examples and insights based on our experience.
Key Differences Between Enclosed and Open 3D Printers
Enclosed 3D printers have a fully enclosed build chamber with doors or covers on all sides. Open 3D printers leave the build area exposed, often using a simple frame with no side panels or top cover.
Enclosures help stabilize temperature during printing, reduce warping for sensitive materials, and keep out dust or air currents. They also add a physical barrier that can improve safety in some environments. In contrast, open printers are easier to access for tinkering, often lighter, and typically cost less.
Pros and Cons of Enclosed 3D Printer vs Open
This is where the debate of enclosed vs open 3D printer becomes more relevant for actual use cases.
Pros of Enclosed 3D Printers
Better thermal control for materials prone to warping like ABS, nylon, or polycarbonate
Improved part consistency and strength for larger prints
Safer around curious hands or enclosed workspaces
Reduced noise and odor in closed environments
Cons of Enclosed 3D Printers
More expensive
Harder to modify or repair
Slightly more limited in build volume at the same price point
Pros of Open 3D Printers
Lower initial cost
Easier access to the print bed and components
More community support for modifications
Better ventilation for materials like PLA or wood-infused filaments
Cons of Open 3D Printers
Poor performance with warp-prone filaments
Increased risk of failed prints due to airflow or drafts
Less protection from contaminants and damage
Can be louder and less safe in shared spaces
Tradeoffs when Deciding on Enclosed and Open 3D Printers
Based on our hands-on experience, cheap open printers often struggle with large prints even when using such materials as PLA or PETG. A few recurring problems include thin heated beds bowing under thermal stress, weak frames vibrating during tall prints, and uneven part cooling that leads to corner lifting. These mechanical issues can lead to failed prints that have nothing to do with slicer settings or filament quality.
When to Choose Enclosed vs Open 3D Printer for Your Project
For small, simple parts in PLA, an open printer is often good enough, especially when budget matters. In fact, many users first choose open printers for cost reasons. These models are often DIY kits that require tuning and patience, but offer savings in exchange.
However, if you are printing with high-shrink materials, large parts, or functional components that demand stability, we recommend an enclosed printer. Controlled temperature and environmental isolation lead to better consistency and fewer failures, especially on longer prints.
In our 3D printing service company, we rarely print materials beyond PLA or PETG on open machines. Even for PLA, large footprints can present challenges as they require stable frames and heavier beds.
How Frame Style Impacts Material Choices
The enclosure can directly affect what materials you can use reliably. Below is a simple comparison of material performance across printer styles:
This table simplifies many nuances, but the key takeaway is that enclosed printers give you more material flexibility and print reliability.
To improve adhesion when printing large parts with warp-prone materials, one helpful tool is a 3D print brim, especially when using an open printer.
Other Factors to Consider while Choosing a 3D Printer Enclosed vs Open
Beyond the printer frame, keep in mind the following:
Print size - Larger prints benefit more from enclosure
Print location - Open printers are noisier and release more odor
Maintenance - Open printers are easier to modify
Safety - Enclosed printers may be better in shared spaces
If you are going to 3D print multiple jobs using various materials, having both types may be useful. However, if you need only one machine, make your decision between enclosed 3D printer vs open based on print size, material types, and workspace environment.
Practical Considerations
The debate of 3D printer enclosed vs open is not just about appearance. Each option fits a different need. For those with a limited budget or those printing in PLA, open printers offer flexibility and value. For advanced users or production jobs, enclosed 3D printers may offer more reliable results across a wider material range.
