Questions about instant quoting
What people ask most before uploading a file.
- What is an instant quote?
- It is a price that comes from your file right away, without forms or back-and-forth emails. At PREMSA the quote starts when you drop your STEP, STL or 3MF: you see the part in 3D, its dimensions and its manufacturability check within seconds.
- Is the price instant for every process?
- Yes. For CNC machining and FDM 3D printing, price and lead time appear instantly. Only some complex geometries or parts with a technical drawing go to engineering review before the price is confirmed.
- Which files can I upload?
- STEP or STP (recommended), STL and 3MF to see your part in 3D; DXF or DWG for flat parts; and PDF or images for the drawing. No CAD file yet? You can request a manual quote.
- Do I need an account?
- Not to start: upload your file and see your part without signing up. To save the quote we ask for your email, and you can continue as a guest or create an account.
- Is there a minimum order?
- No. You can quote a single part, and when you change the quantity you see the unit price drop as setup is spread across more parts.
- How do I pay?
- Online, by card (or SPEI transfer in Mexico). Companies with approved credit pay on their terms.
- Do you ship outside Mexico?
- Yes, to 52 countries. Import duties are paid by the receiver, but you see an estimate before paying, and we prepare the customs paperwork.
- Are my files confidential?
- Yes. They are stored encrypted, only the staff quoting and making your part can see them, and we sign NDAs with your template or ours.
Instant quotes for custom parts: what they are and how they work
An instant quote is a price that comes from your file, not from an email thread. At PREMSA you upload your 3D model (STEP, STL or 3MF) to the online quoting platform and within seconds you see the part spinning in 3D, its exact dimensions and eight manufacturability checks.
Pricing is immediate for CNC machining —milling and turning— and FDM 3D printing, calculated for your part with the material, finish and quantity you choose. Only some complex geometries or parts with a technical drawing go to engineering review before the price is confirmed.
Quote from a single part, change the quantity and watch the price drop, download the PDF if you need it and pay online. We manufacture in Monterrey, Mexico, and ship to 52 countries with customs paperwork included.
