Aortha Sandwich CAD-CAM Blocks- Black Grey Sky

Supports Customised Orthotic Design

What Aortha Tri-Density Sandwich EVA CAD-CAM Does and How Does It Works?
The block acts as the raw material from which a custom foot orthotic is milled. A digital orthotic design is transferred to compatible CAD-CAM equipment, which removes material from the block to create the required shape, contours and functional zones.
Its tri-density construction places EVA layers of different Shore A hardness values together in one block. The firmer black Shore A80 layer can provide a more supportive or durable base, while the softer grey Shore A20 and sky-blue Shore A30 layers can contribute cushioning and accommodation, depending on how the orthotic is designed and milled. The final performance of the device depends on the prescription, orientation of the block, milling depth, geometry, finishing process and footwear in which the orthotic will be used.
Common Problems It May Help Address
When incorporated into an appropriately assessed and prescribed orthotic device, this material may be selected for designs intended to manage:
- Localised areas requiring cushioning or pressure redistribution.
- Foot fatigue associated with prolonged standing or walking.
- Support requirements linked to altered foot mechanics or instability.
- The need to combine a firm orthotic base with softer patient-contact layers.
- Comfort requirements in clinical, daily-wear or activity-specific orthoses.
This block is a fabrication material rather than a treatment by itself. Clinical outcomes depend on assessment, prescription, manufacturing accuracy and patient adherence.
Applications and Suitability
Typical applications
- Custom foot orthotic manufacture.
- CAD-CAM and CNC milling workflows.
- Multifunctional orthoses requiring different firmness zones.
- Clinical, rehabilitation, daily-wear or activity-specific orthotic designs.
- Prototype and small-batch orthotic laboratory production.
Typical users
- Podiatrists.
- Orthotists.
- Orthotic laboratory technicians.
- Footwear and medical-device production teams.
- Clinicians working with appropriately equipped fabrication facilities.
Who It May Not Suit
- Consumers looking for a ready-to-wear insole or finished orthotic.
- Users without suitable CAD-CAM milling equipment and workshop extraction.
- Applications requiring a material specification different from the stated Shore A80, A20 and A30 combination.
- Cases where a qualified practitioner has advised that EVA is unsuitable for the intended orthotic prescription.
- Production environments that cannot safely machine, collect and dispose of foam dust and offcuts.

Usage Instructions
- Assess the patient and create an appropriate orthotic prescription and digital design.
- Confirm that the block dimensions and three-density arrangement suit the intended device and milling strategy.
- Orient and secure the block in the CAD-CAM or CNC milling system according to the machine supplier’s instructions.
- Select tooling, spindle speed, feed rate and cutting depth suitable for EVA foam and the equipment being used.
- Mill the orthotic while using appropriate dust extraction and workshop controls.
- Inspect the finished device for surface quality, dimensions, layer position and structural integrity.
- Complete any necessary grinding, shaping, covering and final fitting before patient use.
Benefits
Functional versatility
Three firmness levels allow the orthotic designer to combine support, cushioning and accommodation within one milled device.
Reduced preparation
The pre-bonded sandwich format can remove the need to assemble multiple separate EVA layers before milling.
Patient-specific production
The block can be shaped according to digital scan data and an individual clinical prescription rather than a standardised insole form.
Workshop clarity
Contrasting colours help technicians identify layer position during setup, machining, quality checks and finishing.
Contraindications and Warnings
- This is a professional fabrication material and is not a finished medical device or ready-to-use insole.
- Orthotic prescription, manufacture and fitting should be completed by suitably trained personnel.
- Do not use a block that is damaged, contaminated, distorted or showing separation between layers.
- Confirm machine compatibility, workholding and cutting parameters before starting production.
- Use suitable local extraction and personal protective equipment when machining EVA, in line with workplace procedures.
- Keep the material away from excessive heat, open flames and incompatible chemicals.
- The suitability of the finished orthotic must be checked for the individual patient, intended activity and footwear.
Frequently Asked Questions
What is this CAD-CAM block used for?
It is used as a milling blank for producing custom foot orthotics with CAD-CAM or CNC equipment. The finished device is shaped from a digital prescription created for an individual patient or application.
What does tri-density mean?
Tri-density means the block contains three EVA layers with different Shore A hardness values. This enables a technician to incorporate firmer and softer material zones into one orthotic, depending on its orientation and the milling design.
What are the densities of the three layers?
The black layer is Shore A80, the grey layer is Shore A20 and the sky-blue layer is Shore A30. Shore A values describe material hardness, with the higher number representing the firmer layer in this combination.
Who is this product intended for?
It is intended for podiatrists, orthotists, orthotic laboratories and trained technicians who manufacture custom foot devices. It is not designed for direct consumer use without professional fabrication and fitting.
Can it be used to make orthotics for daily wear?
It may be used to produce an orthotic intended for daily wear when the material combination suits the clinical prescription and footwear. The practitioner should confirm fit, comfort, function and available shoe space before routine use.
Can the block be used for sports or rehabilitation orthotics?
It can be considered for activity-specific or rehabilitation designs where its density profile meets the required prescription. The finished orthotic should be assessed for the intended load, footwear, movement pattern and frequency of use.
Does the block treat plantar fasciitis or heel pain?
The block itself does not treat a condition because it is only a manufacturing material. A clinician may choose it as part of a custom orthotic design intended to support a wider management plan for heel pain, plantar fascia symptoms or other biomechanical needs.
Does it need to be laminated before milling?
The three densities are already supplied together in a sandwich block, so separate assembly of those layers is not normally required. Additional top covers or finishing materials may still be added if specified in the final orthotic design.
What size is the block?
The block measures 350mm × 300mm × 35mm. Check these dimensions against the intended orthotic size, pair layout, machine bed and workholding method before machining.
How should the correct layer orientation be chosen?
Layer orientation should be decided as part of the digital design and clinical prescription. Consider where firmness, cushioning and accommodation are required, then confirm that the planned milling depth will position each layer correctly in the completed device.
