Fabrication additive vs impression 3D : améliorez votre expérience de paintball

• How it Works: Imagine a hot glue gun controlled by a computer, building an object layer by layer.
• Strength and Quality: Similar to building with LEGO bricks—sturdy for simple shapes but may have visible layer lines.
• HR Tactical Innovations Use: We use FDM sparingly, primarily for high-cost prints where the value isn't justified for SLS or MJF printing. It's also suitable for reducing costs on low-stress parts where visible layering won't compromise visual aesthetics.

• How it Works: Picture a bed of fine powder transformed into an object by a laser, like crafting with sand.
• Strength and Quality: Robust and smooth prints—think of it as building sandcastles with solid sand.
• HR Tactical Innovations Use: SLS is a preferred method for many of our components, especially those that require durability and precision.

• How it Works: Think of a snowy landscape turned into an object using agents and heat, similar to shaping a snow sculpture.
• Strength and Quality: Strong parts with a good surface finish—like crafting with compacted snow.
• HR Tactical Innovations Use: MJF is an excellent choice for parts that require strength, surface finish, and cost-effectiveness. It's often used for larger components and those with moderate complexity.

• How it Works: Visualize a pool of liquid resin sculpted into an object by a laser, like working with liquid glass.
• Strength and Quality: Incredibly smooth and detailed prints—perfect for intricate designs.
• HR Tactical Innovations Use: SLA is employed for parts that demand the highest level of detail and aesthetics, ensuring that every fine detail is captured. We also use SLA smooth resin for airtight fittings that may not be visible or for clear printing.

Tumble polishing involves using abrasive media to remove imperfections and create a smoother surface finish on SLS and MJF 3D prints. It's efficient and provides uniform results.

Vapor smoothing, on the other hand, utilizes solvent vapor to melt and fuse outer print layers, achieving an ultra-smooth finish, especially suitable for complex geometries.

Dyeing SLS or MJF printed parts with Rit Dye is a method to change the color of the parts while maintaining their texture and surface finish. This process involves submerging the parts in a hot dye bath, which allows the dye to penetrate the material. It's an effective way to customize the color of your parts.

Pros:

• Easy and cost-effective method.
• Allows for coloring parts uniformly.
• Works well for porous and textured surfaces.

Cons:

• Limited color options based on available dyes.
• Requires careful temperature control and timing.
• Can be messy, so wear gloves and protect your workspace.

Painting SLS or MJF printed parts with acrylic spray paint offers a wide range of color choices and allows for intricate detailing. This method involves applying thin, even coats of paint to the parts' surfaces. It's suitable for achieving vibrant colors and specific color patterns.

Pros:

• Offers a broad spectrum of color options.
• Allows for detailed and customized designs.
• Can achieve various finishes, including glossy or matte.

Cons:

• Requires surface preparation (sanding and priming) for best results.
• May involve masking for intricate designs.
• Requires adequate drying time between coats and after finishing.
