SLA 3D Printing

Maximum part size depends on the selected manufacturing process and available equipment. For FDM, Stratnel can produce parts up to approximately 1 metre in each dimension, subject to part geometry and machine availability.

Larger components may be divided into sections, printed separately, and assembled. Stratnel can design and print dedicated assembly fixtures to help align such sections accurately.

SLA, SLS, and vacuum casting are generally used for smaller components, often around 200 mm, although actual capacity depends on the selected equipment, geometry, and process. Please share your design so that we can confirm feasibility.

Stratnel offers a broad range of polymer materials. The appropriate material depends on the application, operating environment, required properties, and manufacturing process. Typical options include:

• FDM: ULTEM™ 9085, PA6-CF, ASA, PETG, ABS, PLA, PC-ABS-FR, and other engineering thermoplastics.
• SLS: PA12 (Nylon) for rigid parts and TPU 88A for flexible parts.
• SLA: Standard, tough, clear, and other application-specific photopolymer resins.
• Vacuum casting: Tough, clear, glass-filled, flexible, and other polyurethane resin systems.

Share your application and performance requirements with Stratnel, and we can recommend a suitable process and material. Relevant material datasheets can also be provided.

The achievable accuracy depends on the printing process, material, part geometry, orientation, size, and post-processing requirements. Unless otherwise agreed, our indicative process tolerances are:

These are general process guidelines and do not constitute a tolerance commitment for every feature. Please identify all critical dimensions and tolerances in a drawing when requesting a quotation so that Stratnel can review their feasibility and agree on an appropriate inspection plan.

Measurements are typically taken using calibrated vernier callipers and/or a height gauge on a surface plate. Our standard inspection generally covers selected, readily measurable dimensions across the three principal axes; it is not a complete inspection of every dimension in the drawing or CAD model. Full dimensional inspection or inspection of additional characteristics can be arranged when agreed before production.

Production lead time depends on current machine availability, the size and geometry of the parts, print duration, order quantity, material, post-processing, inspection, and packaging requirements. Finishing processes such as painting may add a few days to the schedule.

We will provide an estimated dispatch date when quoting or confirming your order.
