The Blood Sprayer
Driven by a passion for authentic storytelling, we embarked on a journey captured in this exclusive behind-the-scenes video. Our mission? To bring a unique cinematic effect to life. As we set out to create a relentless, gore-drenched blood spray that seamlessly integrates with our actor's gripping chainsaw scene, we encountered challenges that pushed the boundaries of our DIY filmmaking skills. This video is not just a how-to guide, but an unfiltered glimpse into our determination to craft impactful cinema. Join us as we share the genesis of this project and navigate the unexpected obstacles that arose along the way, finding ingenious solutions in the eleventh hour. For DIY filmmakers seeking hands-on, real-world insights, this video is a treasure trove of lessons learned and creative triumphs. Witness how we achieved the awe-inspiring blood rain effect and meticulously crafted a blood squib, using innovative SFX tools and a 3D printed blood sprayer to deliver a realistic and cinematic blood splatter tool. This journey exemplifies the art of practical effects and prop design, offering invaluable knowledge for aspiring filmmakers in the realm of horror film effects.
The Blood Sprayer Designs
MK I
This is our initial attempt at the Blood Sprayer, a three-part design consisting of the Body, Lid, and Cap. We carefully designed the threads to connect seamlessly to a garden hose. This innovative setup enables easy filling of the chamber with imitation blood. By attaching a garden hose on one end and a custom spray connector on the other, you can achieve a captivating spray effect as the water mixes with the fake blood. This not only enhances the visual impact but also optimizes output while conserving resources. However, we encountered an issue with the seal between the Body and Top. The force of running water against the full blood chamber resulted in excess pressure, causing the lid to give way.

MK II
Our second iteration of the Blood Sprayer, known as MK II, introduces a simplified design that significantly reduces 3D printing time. This version eliminates the need for a separate chamber, as we discovered that a water bottle shares the same thread pitch as a garden hose. To set it up, fill the bottle three-quarters full and securely attach it to the device using the threaded mechanism, preventing any potential pressure-related accidents. Connect the specialized sprayer and the hose. As the water from the bottle combines with the 'blood', it will flow out through the sprayer. Initially, the liquid will remain clear as the two substances have not yet mixed. When the water is turned off, the remaining pressure in the line will be released through the sprayer, generating a dense squib effect that persists until the pressure subsides. Please note that this design may have minor leaks resulting in some drips, potentially causing the user to get wet. Exercise caution around sensitive equipment. Feel free to download and utilize this design, or take the opportunity to make improvements.
