What does the required PC configuration depend on?
It mainly depends on the size of the STL file and the number of parts you want to split.
Larger or more complex models require more CPU power, more RAM, and fast storage to process efficiently.
The minimum screen resolution is 1920x1080.
Driver Requirements
Up-to-date GPU drivers, Split3r relies on OpenGL for hardware-accelerated 3D rendering. Please ensure your graphics drivers (NVIDIA, AMD, or Intel) are updated to the latest version to avoid display issues or crashes.
Local Storage Requirement
Split3r must be installed on a local drive, we advise the default: C:\Program Files\Split3r_x.x.x, (x representing the version number), and all files to be processed should also be stored locally, not on a cloud-synced folder such as Dropbox, OneDrive, or Google Drive.
During a split session, Split3r launches multiple Blender instances simultaneously and generates a large number of intermediate files that can be quite heavy.
Cloud sync services will attempt to upload these files in real time as they are being written, which leads to file access conflicts, severe performance degradation, and crashes.
Best practice: Copy your STL files to a local folder such as C:\Users\[YourName]\Documents\Split3r before processing.
Once the split is complete, you can move the results back to your cloud storage if needed.
What kind of PC is suitable for small STL files (under 4–5 MB) split into 4 to 8 parts?
For light STL files and simple cuts, Split3r does not require a high-end system. A standard configuration is sufficient:
CPU: Intel Core i5 or equivalent
RAM: 8 Gb
Storage: 256 Gb SSD
Graphics: Integrated GPU (Intel/AMD), OpenGL-compatible
This setup handles basic operations smoothly.
What configuration is recommended for large STL files (around 30 MB or more) split into dozens or hundreds of parts?
For heavy models or advanced splitting operations, a more powerful system is recommended:
CPU:
Minimum: Intel Core i7
Recommended: Intel Core i9 or equivalent AMD Ryzen (higher frequency = faster processing)
RAM:
Minimum: 16 Gb
Recommended: 32 Gb for optimal comfort. If you plan to work on very large STL (500Mb and more) 64Gb or 128Gb RAM maybe needed.
Storage: 1 Tb SSD (NVMe preferred)
Graphics: OpenGL compatible GPU with 4–8 GB VRAM
If you plan to work on very large STL (500Mb and more) 64Gb or 128Gb RAM maybe needed.
Can I use Split3r on a laptop?
Yes, as long as the laptop includes:
a NVMe SSD,
and a GPU that supports OpenGL.
Low-power CPUs (U-series) will work but are noticeably slower than H or HX models.
Do I need a dedicated graphics card?
Split3r can run with integrated graphics, but for large models or intensive 3D visualization:
a dedicated GPU (NVIDIA or AMD) offers significantly better performance and smoother rendering.
What configuration should I choose to be future-proof for several years?
For all types of STL files, including very large ones, we recommend:
Core i9 / Ryzen 9,
64 Gb RAM,
1 TB NVMe SSD,
OpenGL GPU with 6–8 GB VRAM.
This ensures fast calculation times and smooth 3D visualization.
Does Split3r use the GPU for computations?
The GPU is used primarily for 3D visualization.
Splitting operations rely only on the CPU and system RAM.
