FAQ

Our team is available Monday to Friday, 10:00 AM – 6:00 PM KST (UTC+9). For inquiries outside business hours, leave a message via the 1:1 inquiry form or email support@creallo.com and we'll respond in order. 
 

A 3D model (STEP, STL, etc.) is required for production.
If you only have 2D drawings (DWG, DXF), we can provide a simplified quote, but actual manufacturing requires a 3D model. We recommend preparing a 3D file before submitting your request.

There's no minimum order quantity — we accept orders starting from a single unit.

However, a minimum order value (MOV) applies per manufacturing process. If your part cost falls below this threshold, the difference appears as a separate "Additional Fee" line item, clearly itemized before you confirm payment.

To reduce or avoid this fee, consider increasing your quantity or combining multiple parts that share the same material and finish into a single order.

The MOV table below is shown in KRW. For customers receiving quotes in USD, the KRW amount is converted at the exchange rate applied at the time of order.

Our AI-powered DFM (Design for Manufacturability) analysis automatically reviews your file at the quoting stage — flagging issues like wall thickness, tolerances, and feature geometry before production begins.  

• Pass / Proceed — No issues detected. You can proceed directly to payment.  
• Warning / Needs Attention — Potential issues flagged. You may proceed once you've reviewed the highlighted risks and agreed to continue.  
• Fail / Cannot Proceed — The design cannot be manufactured as submitted. Please revise your file based on the feedback and re-upload.  
• Detailed Review Required — The AI could not automatically determine manufacturability. Click the "Final Review Request" button before payment. Manual review typically takes 15 minutes to 1 business day depending on model complexity. 

For more complex parts, our engineering team provides a manual review with actionable recommendations. This means fewer surprises, faster turnaround, and lower risk of rework. 

Available finishes vary by process and include options such as sanding, painting, anodizing, plating, and bead blasting. For painted parts, Creallo supports Pantone color matching — use the Creallo Pantone Color Finder to check available colors and apply them directly within the real-time quoting system to see pricing and lead time instantly. Note that hand-mixed colors may have slight variations from the reference.

Contact us within 7 days of receiving your order with clear photos and a description of the issue. You can reach us by clicking the Contact Us button (circular icon, bottom right of the page).

Our team will review the documentation and guide you through the return process. Once confirmed, we will arrange re-production or a refund as quickly as possible.

Upload your CAD file (STEP, STL) to our online platform. For 3D printing and Vacuum Casting, you'll receive an AI-generated instant quote in seconds — including real-time pricing and DFM feedback as you adjust materials or quantities. For CNC processing, sheet metal and injection molding, submit a quote request and our team will respond within 24 hours. 

Creallo is certified under ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 27001 (Information Security Management). Every order goes through in-process quality inspection and, where applicable, final inspection with photographic documentation before shipment.

For critical dimensions, we can provide an inspection report on request. 

Yes. Most of our commonly used materials — including aluminum alloys, stainless steel, and engineering-grade plastics — are sourced from suppliers whose materials comply with RoHS and MSDS directives. Upon request, we can provide material certificates of conformity or third-party test reports. Please specify your target standard when submitting your quote so we can confirm compatibility upfront. 

Yes. Material mill certificates, certificates of conformity, and inspection reports (including dimensional reports and photographic inspection records) are available upon request. Please let us know your documentation requirements via 1:1 inquiry window or email.

All files uploaded to our platform are encrypted in transit and at rest. Creallo is ISO 27001 certified — the international standard for information security management — and we have recorded zero data breaches. NDA agreements are available upon request before you share any files. Your design data is never shared with third parties without your explicit consent. 

Economy pricing is lower than Standard, but ships slower. Standard costs a bit more but turns around faster than Economy. For Expedited requests, your account manager will confirm feasibility and pricing case-by-case at the time you ask — depending on shop capacity, expedited turnaround isn't always available.

Instant quotes generated through our online tool are available immediately. Quotes that need manual review from our team are typically turned around within 1 business day.

Files over 50MB can be submitted through a support ticket, which allows uploads up to 100MB. If your file is still too large even for that, you can email us at support@creallo.com instead.

To help us process your request faster, please include:

1. One part per file (don't combine multiple parts into a single file)
2. Manufacturing process
3. Material
4. Any finishing/post-processing needs
5. Quantity and target lead time

If there's a mismatch between your 3D model and 2D drawing, we won't automatically default to either one — your account manager will flag the discrepancy and follow up with you directly. If you want manufacturing to follow the 2D drawing, please update your 3D model to match it and resubmit.
