3D Printing Quote Checklist: 12 Details to Include When Requesting a Quote

Quick answer: For an accurate 3D printing quote, include your 3D file in STL, OBJ, or STEP format, the units and overall size, quantity, material, printing technology, what the part will be used for, critical dimensions, colour, surface finish, strength needs, deadline and delivery location, and billing details such as your GSTIN. The more complete your request, the more accurate the price and the faster your parts reach production. 3Ding's instant quote captures most of these details automatically and shows the price in seconds.

A 3D printing price depends on more than the shape of your part. Material, quantity, finish, and timeline all change the cost and the production plan. When a request is missing key details, the quote has to be revised, and every revision costs you time.

Use this checklist to get an accurate quote on the first try. If you use 3Ding's instant quote, most of these details are handled for you, and you see the price in seconds.

1. Your 3D File: Where Every Accurate Quote Starts

The 3D file is the foundation of every quote. It tells the provider the exact volume and size of your part, which drives most of the price.

• STL is the most widely used format for 3D printing.

• STEP keeps exact geometry from your CAD software, which is ideal for engineering parts.

• OBJ works well for models exported from design and modelling tools.

If your order has several parts, name each file clearly, for example "enclosure-top.stl" and "enclosure-base.stl", so nothing gets mixed up. Our guide to 3D printing file formats explains each format in more detail.

With 3Ding's instant quote, upload any of these three formats and the price is calculated from your file straight away.

2. Units and Dimensions: The Missing Detail That Can Shrink Your Part 25 Times

STL files carry no units. A part designed in inches can be read as millimetres and quoted at a fraction of its real size. Always confirm the units and check the overall dimensions (length, width, and height) in the quote preview before you continue.

Size also tells the provider whether the part fits in one piece on their printers.

With 3Ding's instant quote, the 3D preview lets you check the part on screen before you continue.

3. Quantity: Why 1 Part and 100 Parts Are Priced So Differently

Quantity changes the price per part and the production plan. Printing one prototype is very different from printing 100 identical parts.

State how many you need now, and mention if you expect repeat orders. Knowing the full picture helps the provider plan production and keep your parts consistent from batch to batch.

4. Material: The Choice That Decides Strength, Heat Resistance, and Price

Material affects strength, heat resistance, flexibility, appearance, and price. If you know what you need, name it:

If you are unsure, describe how the part will be used (see point 6) and compare materials in the quote.

With 3Ding's instant quote: switch between materials and colours and watch the price update instantly. Our PLA vs ABS vs PETG guide can help you decide.

5. Printing Technology: FDM or Resin, Which One Does Your Part Need?

The two most common technologies are FDM and resin printing. FDM is practical for functional parts, enclosures, brackets, and larger prototypes. Resin printing suits small, detailed parts that need a smooth finish.

If you are not sure which one fits, ask for both in your quote so you can compare price and quality. Our FDM vs SLA vs SLS vs MJF guide explains the differences.

6. Part Use: The One Line That Helps You Get the Right Material

A short description of the part's job helps the provider recommend the right material and print orientation. Include details such as:

• Will it carry a load or be screwed to something?

• Will it be near heat, outdoors, or in contact with water or chemicals?

• Does it need to flex, snap together, or fit another part?

• Is it a functional part, a prototype for review, or a display model?

One or two lines are enough, and they can save you from choosing a material that won't last.

7. Critical Dimensions and Fits: Flag What Must Be Exact

If some features must be accurate, such as holes for bearings, mounting points, or parts that slot together, point them out. A simple PDF drawing or a marked-up screenshot showing the critical dimensions is very helpful for engineering parts.

For parts that must fit together, mention the fit you want, whether tight, sliding, or loose, so the provider can advise on clearance.

8. Colour: A Small Detail That Can Change Availability and Price

Colour can affect material availability and price. State the colour you need, or say if any colour is fine. If the part must match a brand colour or an existing product, mention that clearly.

9. Surface Finish: Straight Off the Printer or Ready for Display?

Mention how the part should look and feel. A functional bracket may be fine straight off the printer with supports removed. A display model or customer-facing product may need a smoother surface or further finishing.

If you plan to paint, glue, or assemble the parts yourself, say so, because it can change how the provider prepares them.

10. Strength: Describe the Load, Not the Print Settings

For FDM parts, strength depends on wall thickness, infill, and orientation. If the part needs to be especially strong, light, or rigid, include that in your request.

You don't need to know the exact print settings. A plain statement such as "this bracket holds a 2 kg motor" gives the provider what they need.

11. Deadline and Delivery: Work Back from the Date You Need Your Parts

Share the date you need the parts by and where they should be delivered, including the PIN code. This helps the provider confirm production time and choose the right shipping option.

With 3Ding's instant quote: the production time appears with the price, so you can plan before you pay.

If you are close to the provider, ask whether self-pickup is available, as it can save both time and shipping cost.

12. Billing Details: Get Your GST Invoice Right the First Time

If you are buying for a business, include the company name, billing address, and GSTIN so the invoice is correct the first time. Registered businesses generally need a GST invoice to claim input tax credit. If your company uses purchase orders, mention the PO number in your request.
