HPPS Foamed Silicone Insulation

Unlock new capabilities by adding HPPS to your 3D printer. Take on larger and more complex projects in demanding materials without the fear of warping while consuming significantly less electricity, reducing chamber warm-up times, and protecting your investment.

Since 2023, the High Performance Panel System (HPPS) has set the gold standard in 3D printer insulation. Deployed across seven continents, HPPS continues to deliver consistent, proven performance in the most demanding environments.

HPPS 2.1 for X1C/E & P2S

HPPS 2.1 for X1C/E & P2S

The classic HPPS reinvented, increasing chamber temperatures by +10 to 15°C, improving chamber temperature consistency, and reducing time-to-hot chamber performance while lowering power consumption by up to 35%. HPPS delivers the superior heated chamber experience without the associated risks, power consumption, and thermal emission of a heater. It is manufactured from our unique, aerospace-derived foamed silicone insulation material — the same material we use to insulate systems that fly all over the world (though we still wish it made our printers fly too!). In production since 2023, HPPS has surpassed 700 units sold on 7 continents.

HPPS 2.1 for H2S/D/C

HPPS 2.1 for H2S/D/C

HPPS for the Bambu Labs H2 Series delivers substantial reductions in thermal emissions, significant power savings, and dramatically improved thermal stability. “Big HPPS” began as an internal project to evaluate the impact HPPS would have on an H2D running engineering-grade materials. The most immediate benefit was the sharp reduction in heat radiating from the printer, along with a chamber temperature that would consistently rise to 60°C when set to 40°C with recirculation enabled — an immediate demonstration of the system’s sheer efficiency.

In side-by-side comparisons printing real-world ASA parts, we consistently measured 30–40% reductions in power consumption and up to 40% faster time-to-chamber-hot performance.

Quite frankly, we wouldn’t run an H2 without HPPS if there’s any possibility you’ll be printing higher-temperature materials.

And yes — the foamed silicone insulation is extremely durable. It has saved us more than once during accidental door and top-glass impacts.

HPPS: The Gold Standard in 3D Printer Insulation

UILB

HPPS delivers unmatched thermal performance and stability, raising Z-axis chamber temperatures by 10–15 °C without exposing hardware to extremes. Strategically located & formulated, it retains heat where needed while allowing airflow for cooling and has proven reliability across 300,000+ hours of high-temperature printing.

Thermal Performance

HPPS foamed silicone insulation was created to safely insulate our X1C print farm with minimal ignition risk. Leveraging aerospace- and medical-grade foamed silicone, we developed a high-performance solution that quickly gained traction. Since 2023, we’ve refined its performance and consistency, operating on a cost-plus model in order to maximize adoption. HPPS is proudly based in New Hampshire, USA.

Unique Foamed Silicone

HPPS delivers transformative energy efficiency for passive and heated chambers, cutting 20–40% of power use and easing HVAC load. HPPS for H2 turns a printer that once felt like a space heater into a thermally contained machine. Built for real-world durability, it protects front and top glass—one customer even survived a 1/2” impact wrench drop with no damage, prompting additional orders for workplace safety.

Efficiency & Durability

We built HPPS for a quick & repeatable deployment for users with 1 to 100 machines. Unlike a DIY solution, the HPPS install is intuitive & rapid (under 3 minutes per machine); requiring no measurement, cutting, or added adhesive. HPPS is built to just, work.

Deployability

HPPS 2 is Foamed-Silicone for all

HPPS pricing is designed around a fixed, cost-plus pricing model. At it's core HPPS is a community-centered project designed to allow the best foamed-silicone insulation to be available without spending 2-3x our pricing. Originating from aerospace, HPPS is the gold standard in professional 3D Printer insulation.
