Draft V2 Resin - Print Fast, Prototype Faster

February 25, 2021

The Formlabs materials innovation team is always hard at work bringing new resins and improving on current ones. One of the most notable resin improvements recently is Draft V2 Resin.

You can now print faster than Draft V1, and at the same time print at higher resolutions. Overall, you can print up to 4-5 times faster than standard resins like Black, Grey, White, and Clear.

Differences between Draft V1 and V2 at a glance:

	Draft V1	Draft V2
Print quality (layer height)	300 microns	100, 200 microns
Colour	Blue	Light Grey
Speed	Fast	x4-5 faster than standard resins
Compatibility	Form 3, Form 3L, Form 3B, Form 3BL, Form 2 (LT Tank Required)	Form 3, Form 3L, Form 3B, Form 3BL, Form 2 (LT Tank Required)
Post curing	Not required	Optional to bring about better material properties

How much faster is Draft V2 in practice?

Speed Analysis is based on 4 large identical parts:

Comparison Table

* Sliced and prepped for the Form 3 *	Grey V4 Standard Resin - 100 microns	Draft V2 - 100 Microns	Draft V2 - 200 Microns	Draft V1 - 300 microns
Resin used	277.09 mL	275.19 mL	276.48 mL	278.68 mL
Print time	24.75 hours	9.75 hours	5 hours	6.91 hours
Speed	11.2 mL / hour	28.22 mL / hour	55.30 mL / hour	40.33 mL / hour
Speed compared to Grey V4	NA	252% faster than Grey V4	494% faster than Grey V4	360% faster than Grey V4

Print Quality

The print quality between Draft V1 and V2 is obvious. V2 is much better because it can print at finer layer heights so parts don't have visible layer lines.

How does it compare to standard resin? You be the judge! Below you can see a side by side comparison between grey standard resin (100 microns) and Draft V2 (200 microns), to us this surface finish is great for prototypes while offering great time savings.

Conclusion

Draft V2 should be your go to resin when you need something printed the same day in good print quality and when finer resolutions (25, 50 microns) are not needed. Draft V2 is perfect when you are doing true rapid prototyping.
