Return to the homepageThis page is the single source of truth for the equipment limits we publish. We name the fleet because it is more useful than a generic claim about a process. The final choice of machine, material, orientation, nozzle and support follows a review of the actual geometry and the environment the part has to survive.
Every figure below is a manufacturer specification for the machine named, not a measurement taken by us. It is not a guarantee of part performance. Parts are reviewed individually because geometry, material and build orientation change the result.
Machine capability is only one side of the decision. Compare FDM and resin printing by the part’s function, detail and surface requirements.
Each machine has a distinct job. The fleet table is a starting point for choosing where a part belongs, not a substitute for the review that connects a model to a material and its intended use.
| Machine | Role | Envelope | Nozzle range or panel | Chamber or resin |
|---|---|---|---|---|
| Bambu Lab H2D | Dual-nozzle, enclosed, heated chamber | 350 × 320 × 325 mm | 0.2–0.8 mm | 65 °C actively heated |
| Bambu Lab H2S | Single-nozzle, enclosed, heated chamber | 340 × 320 × 340 mm | 0.2–0.8 mm | 65 °C actively heated |
| Bambu Lab X2D | Dual-nozzle, enclosed, heated chamber | 256 × 256 × 260 mm | 0.2–0.8 mm | 65 °C actively heated |
| A1 farm | Open-frame array, parallel capacity | 256 × 256 × 256 mm | 0.2–0.8 mm | Open-frame |
| Elegoo Saturn 4 Ultra 16K | MSLA resin, fine detail and smooth surfaces | 211 × 118 × 220 mm | 16K mono LCD | ABS-Like 3.0 |
This is the best published limit available across the named fleet. It does not mean that every dimension, material, nozzle, support strategy and orientation can be combined on every job. We resolve that combination during technical review.
| Single-piece X (mm) | Single-piece Y (mm) | Single-piece Z (mm) | Nozzle maximum (°C) | Bed maximum (°C) | Chamber maximum (°C) | Nozzle range or panel | Layer range (mm) |
|---|---|---|---|---|---|---|---|
| 350 | 320 | 340 | 350 | 120 | 65 | 0.2–0.8 mm | 0.06–0.4 mm |
A material only belongs on a heated-chamber machine when its catalogue record says it requires one. That flag, rather than a family name, is what keeps a material choice tied to the actual grade and its printing requirements. An open-frame machine is not substituted where the selected material needs a held chamber.
The materials catalogue is the authority for the individual grades. If you know the service environment but not the material, include that in your request and we will recommend a route through the fleet.
A geometry that does not fit within the relevant single-piece envelope is not silently forced into a machine. We first look at whether the part can be divided into segments that locate predictably, then propose keys and bond faces that preserve the features that matter. Seam location is part of the review, especially when a surface mates with another part or carries a visual requirement.
Segmenting changes the object. It can add assembly steps, make orientation decisions more consequential, and move a seam into an area that needs a different design. The design guide explains the questions we work through before agreeing that approach.
