Our in-house professional SLA 3D printing service provides highly detailed, smooth resin parts that closely replicate injection moulded finishes. Using advanced SLA resin materials, we produce functional prototypes and components with exceptional accuracy, tailored to meet specific application requirements across industries.
Stereolithography (SLA) is a precision 3D printing technology that cures liquid resin using a controlled laser, producing finely detailed parts with excellent surface smoothness. SLA printing is ideal for components where accuracy, visual quality, and intricate geometries are essential. Our in-house material range covers several advanced engineering resins, each designed to fulfil distinct functional needs, from stiffness and strength to flexibility and visual clarity.
Below you will find the full list of SLA resins available through our additive manufacturing service:
Rigid 4000 is a glass-filled resin that delivers high stiffness and excellent dimensional stability. Its mechanical properties make it particularly suited for applications where components must maintain precise geometry under load.
Applications:
Field insight: Rigid 4000 provides a balance between stiffness and fine detail reproduction, often used in functional validation before moving to full-scale production tooling.
Rigid 10K offers extremely high modulus and minimal creep, making it the stiffest resin option in our SLA range. Its advanced mechanical profile allows it to perform reliably in demanding engineering environments.
Applications:
Field insight: We often see Rigid 10K selected by mechanical engineers working on airflow parts, bracketry, and fixtures where zero flex is critical.
Tough Resin simulates the mechanical performance of ABS thermoplastics, combining impact resistance with moderate elongation. It is well suited for functional testing where parts may undergo stress, flexing, or repeated assembly.
Applications:
Field insight: Tough Resin allows design teams to fully evaluate fit, movement, and durability before committing to hard tooling, saving both time and cost in development cycles.
Flexible 80A replicates rubber-like materials, providing excellent flexibility, tear strength, and elongation. It enables production of elastomeric components directly from CAD models.
Applications:
Field insight: Flexible SLA materials are often used for product design validation where tactile feel and compression properties need to be assessed in the prototype stage.
Standard Clear Resin is designed for general-purpose prototyping where transparency, visual quality, and fine feature detail are the primary requirements.
Applications:
Field insight: Designers often use Clear Resin for early concept visualisation, especially when internal features or assemblies need to be inspected visually.
Selecting the correct SLA resin ensures that prototypes and parts perform as intended during both development and functional testing. For instance, a medical device developer may require Flexible 80A for seals, while a tooling engineer may prefer Rigid 10K for fixturing components that must retain dimensional stability over time.
Field insight: Material selection early in the design process helps identify potential design weaknesses and allows for real-world functional validation, reducing development risk.
SLA resin materials are widely adopted across industries for both prototyping and limited production runs.
Industries and uses:
Example case study:
A product design consultancy developing a wearable medical device used Flexible 80A to prototype silicone-like straps and Rigid 4000 for the device housing. This approach allowed full fitment testing and early-stage user trials before committing to final moulded production.
Our SLA printing capability delivers highly accurate, finely detailed parts suitable for both functional validation and short-run production. The combination of diverse resin options and in-house control allows us to support complex geometries and tight tolerances without the delays of external subcontracting.
Rigid 10K offers the highest stiffness in our SLA resin portfolio, designed for engineering components that must resist flex, creep, and deformation under sustained loads.
Yes. Engineering resins such as Tough (ABS Like) and Rigid 4000 are frequently used for mechanical and functional testing, including snap fits, assemblies, and fixture prototyping.
Standard Clear Resin provides good transparency suitable for visual models and fluid flow studies. Additional polishing or coating can further enhance optical clarity for display parts.
SLA parts can serve as end-use components in specific low-volume or specialised applications, particularly when dimensional accuracy and surface finish are priorities. Materials like Rigid 10K and Tough Resin are most commonly used for this.
SLA resin printing is widely utilised in product design, medical device development, aerospace, automotive, electronics, and any sector requiring detailed, accurate prototypes with superior surface finish.
