/ 01What is Ergono3D?
Ergono3D is a browser-based custom insole design platform that generates 3D-printable insoles and exports print-ready STL files — no CAD software, no foot scanner, and no manual modeling required.
The platform is built for makers, clinicians, orthotic labs, and studios. Describe your foot needs through a short guided survey, review an interactive 3D preview, fine-tune the parameters, and download a print-ready STL compatible with Bambu Lab, Prusa, Creality, and similar FDM printers.
/ 02Do I need CAD software, a foot scanner, or specialist knowledge?
No. Ergono3D is specifically built to remove those barriers. The guided input flow uses smart defaults so you can reach a working 3D insole preview without any CAD experience, scanner hardware, or biomechanics background.
You only need to engage with parameter controls when you want to go further than the defaults.
/ 03How does the workflow go from input to a print-ready STL?
The workflow has four stages:
Step 1 — Smart Input: Complete a short activity-based survey describing foot needs and use case.
Step 2 — Parameters Control: Accept smart defaults or fine-tune arch height, heel cup, posting, skives, flange, and forefoot geometry.
Step 3 — STL Scale & Fit: The platform automatically scales and validates the model for printability.
Step 4 — Dashboard: Download the STL, manage design history, and track compute credit usage.
/ 04Can I preview and adjust the insole before downloading the STL?
Yes. Ergono3D includes an interactive 3D insole preview with real-time model updates. You can review and iterate on the geometry before committing to a download.
The Free Preview Trial gives you 5 preview compute credits at no cost so you can fully evaluate the design before paying. STL download is then A$9.90 one-time, or included in the Lite and Pro credit plans.
/ 05Can I save, re-open, and manage my designs in the Dashboard?
Yes — on paid plans. The Dashboard lets you re-download STL files from previous designs, track compute credit usage and remaining balance, and view design history and export records.
Design saving and the history dashboard are included in the Lite Starter Plan (A$69.90) and Pro Standard Plan (A$199.90). The Free Preview Trial does not include design saving.
/ 06How is Ergono3D different from a generic foam insole or size-scaled template?
Ergono3D generates geometry that responds to individual foot needs — it is a parametric insole design workflow, not a simple size scale of a generic template. The design can be adjusted for arch profile, heel cup depth, posting angles, skives, and other orthotic features that generic insoles do not offer.
The output is a custom 3D-printed orthotic insole, not a foam insert.
/ 07What insole design parameters can I control in Ergono3D?
Core adjustable parameters available on the Lite plan include:
- Arch — height and profile shape
- Heel Cup — depth and lateral/medial wall geometry
- Forefoot — forefoot plate and metatarsal support
- Skives — medial and lateral skive corrections
- Flange — flange width and coverage
- Posting — rearfoot and forefoot posting angles
The Pro and Studio plans also unlock advanced parameter adjustments beyond the core set.
/ 08What do arch height, heel cup, posting, skive, and flange actually mean?
- Arch height — how high the medial arch rises to support the foot's longitudinal arch.
- Heel cup — the raised wall around the heel that stabilises the calcaneal fat pad.
- Posting — a wedge built into the heel or forefoot section to correct pronation or supination angles.
- Skive — a localised bevel or reduction in the insole surface, commonly used for pressure relief or biomechanical correction.
- Flange — the sidewall extension that wraps up along the medial or lateral border of the foot.
/ 09Can I use Ergono3D without biomechanics or orthotics knowledge?
Yes. The guided input flow and smart defaults are designed so beginners can produce a functional insole design without specialist knowledge. Parameters are labelled in plain language, and you only need to engage with advanced controls when you want more precise customisation.
See the Understanding Insole Design Parameters guide for accessible explanations of every control.
/ 10Where is the best guide to understanding all insole parameters?
The dedicated resource is the Understanding Insole Design Parameters guide on the Ergono3D blog. It is the most complete reference for arch support, heel cup, posting, skives, flange, and forefoot geometry in the context of how Ergono3D generates each shape.
For the broader workflow context, also read the Step-by-Step Guide.
/ 11What 3D printers are compatible with Ergono3D STL files?
Ergono3D exports a standard STL file compatible with all major slicer software — Bambu Studio, PrusaSlicer, Cura, and OrcaSlicer. The platform specifically names Bambu Lab, Prusa, and Creality as target printers, but any FDM printer that has sufficient build volume for the insole footprint and can handle flexible TPU filament will work. The STL format is machine-agnostic.
/ 12What 3D printing material should I use for custom insoles?
Ergono3D recommends TPU (thermoplastic polyurethane) for printing custom insoles. TPU is a flexible, durable filament that provides the cushioning and load-bearing properties needed for a functional orthotic insole.
The pricing page includes TPU hardness guidance to help you choose between softer and firmer variants for different applications. For the finished insole, a top cover layer — such as EVA foam, Poron, or fabric — is also recommended for comfort, sweat management, and grip.
/ 13Do I need special slicer settings for 3D-printed insoles?
The STL file from Ergono3D is pre-scaled and validated for printability — load it into your slicer and apply your standard TPU profile. Key considerations:
- Use your printer's recommended TPU profile (slower speeds, lower retraction)
- Check that the insole fits within your build volume
- Infill and wall settings affect stiffness — review the parameter guide for guidance
/ 14What does the Free Preview Trial include?
The Free Preview Trial is A$0 — no credit card required. It includes:
- Advanced survey & activity-based setup

/ 18How do compute credits work?
Credits are the unit of usage for generating and updating custom insole designs:
- 1 credit generates a new insole and unlocks 5 free design updates
- After those 5 updates, 1 more credit = 5 additional updates
- On the Lite plan: per credit = 1 STL export + 5 updates
Credits are valid within your plan's window — 3 months for Lite and Pro; 6+ months for Studio.
/ 19Is Ergono3D a subscription, or can I pay only when I need a file?
Ergono3D is not a recurring subscription. The model is:
- Free preview — no payment needed to evaluate the design
- A$9.90 one-time download — pay only when you need the STL
- Credit packs (Lite / Pro) — buy credits for ongoing design capacity
- Studio Pack — contact pricing for high-volume workflows
/ 20Where should I check the latest plan terms and pricing?
