Draft V2 Resin - Print Fast, Prototype Faster

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.
