How to Prepare a Better RFQ for SLS 3D Printing

Introduction

A good SLS quotation starts before pricing. The quality of the RFQ shapes the quality of the manufacturing review, the usefulness of the engineering feedback, and often the success of the first build.

When a request includes only a CAD file and a quantity, valuable context is missing. The supplier may still provide a number, but the quotation is less likely to reflect what the part really needs.

What a Strong RFQ Should Clarify

A strong quote request helps define:

What the part is for
Which features are critical
Whether the build is cosmetic, functional, or pre-production
Which material tradeoffs matter most
What finishing is actually required

This leads to a more useful quote and a better first-pass result.

What to Include in Your RFQ

1. A Clean, Current File

Start with the latest correct file revision in a standard manufacturing format. If the design includes multiple parts, make sure assemblies and variants are clearly labeled.

2. Intended Use

This is one of the most important notes you can add. Is the part for:

Visual review
Assembly validation
Functional testing
Pilot production
End-use low-volume application

The answer can change the recommended material and finishing route significantly.

3. Critical Features

If one fit, latch, wall, or mounting point matters more than everything else, say so. Without that note, the part may be reviewed as a general print instead of an application-specific engineering component.

4. Material Priority

You do not always need to specify an exact material, but you should explain what matters most:

Higher stiffness
Better flexibility
Better impact resistance
A stable general-purpose nylon
A reinforced structural feel

That allows the supplier to respond with a recommendation instead of just a price.

5. Finish and Hardware Expectations

Clarify whether the part should remain as-printed, be dyed, receive extra finishing, or support threaded hardware. These choices affect both cost and downstream usefulness.

6. Quantity and Timing

Low-volume SLS is especially useful when quantity is moderate and lead time matters. Stating both quantity and target timing helps define the right production path.

Final Takeaway

The best SLS RFQs do more than ask for price. They explain the engineering goal clearly enough that the supplier can provide useful review and appropriate recommendations.

If you want a better first build, start with a better RFQ.
