<p>I am doing laboratory experiments and need to print some components.</p>

<p>I am working with different aqueous (water) solutions containing sulphuric acid (H<sub>2</sub>SO<sub>4</sub>), hydrochloric acid (HCl), and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), separately and in combination. The pH of the solutions are in the range 0 to 7. Temperatures don't exceed 40° Celsius.</p>

<p>In another application we have aqueous solutions containing high concentrations of FeCl<sub>3</sub>, HCl and in some cases H<sub>2</sub>O<sub>2</sub> at temperatures of up to 180° Celsius.</p>

<p>Which 3D printing filament materials can you recommend for these applications?</p>

I would suggest trying a Nylon, PETG or a PolyCarbonate filament as I know these are more resistant to acids than PLA or ABS. As far as strength of the parts, all FDM plastics will work well</p>\n<h1>Application 2 (Temp &gt; 180 °C)</h1>\n<p>This temperature range is above the glass transition temperature of the PLA, ABS, PETG and Nylon are all well below 180 °C and therefore aren\'t worth considering. Your best option is PolyCarbonate, or PolyCarbonate-ABS which are both fairly high (roughly 140-150 °C).
