Translucent Blood Red PLA Prime is made from virgin NatureWorks Ingeo 3D850 resin with colorant only and no fillers. Compared with traditional PLA, it has more heat resistance and toughness, good adhesion, and less warping or curling, and it prints with your existing PLA profiles. Use it for prototypes and display models. All grades of PLA have limits: if a part needs high strength and high heat resistance, look at our other materials.
Translucent Blood Red also comes in Standard PLA.
Recommended print settings
- Hotend: 215–235°C. That may be hotter than you're used to for PLA, because our 100% virgin resin needs slightly higher printing temperatures.
- Bed: 40–60°C. A heated bed is recommended but not required.
- Part cooling fan recommended, up to 100%
- Build surfaces and adhesives: glass, PEI, WELD3D Bed Adhesion Spray, painter's tape or glue stick.
- PLA Prime absorbs moisture from the air. If it under-extrudes, strings or pops at the hotend after exposure to humidity, dry it at 55°C for at least 3 hours.
PLA Prime comes in most of our Standard PLA colors: see all PLA Prime colors.

4. First-aid measures
| Inhalation | Move to fresh air. Call a physician immediately. |
| Eye contact | Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Call a physician immediately. |
| Skin contact | Adverse effects are not expected from accidental skin contact following occupational exposure. After contact with skin, wash immediately with plenty of water. If skin irritation persists, call a physician. Cool skin rapidly with cold water after contact with hot polymer. DO NOT attempt to remove hot polymer from skin or contaminated clothing as skin may be easily damaged. Call a physician immediately. |
| Ingestion | Drink water as a precaution. Never give anything by mouth to an unconscious person. Do not induce vomiting without medical advice. Call a physician immediately. |
| Most important symptoms | No data available |
| Note to physicians | Treat symptomatically. |
5. Fire-fighting measures
| Suitable extinguishing media | Suitable extinguishing media: Foam, Water, Carbon dioxide (CO2), Dry chemical. Alcohol resistant foams are preferred if available. General-purpose synthetic foams (including AFFF) or protein foams may function, but much less effectively. Unsuitable extinguishing media: None known. |
| Special hazards | Under fire conditions: Cool containers / tanks with water spray. Water mist may be used to cool closed containers. Fine dust dispersed in air may ignite. Risks of ignition followed by flame propagation or secondary explosions shall be prevented by avoiding accumulation of dust, e.g. on floors and ledges. Flammability: Autoignition temperature: 388 °C. Flammable limits in air - lower (%): Not applicable. Flammable limits in air - upper (%): Not applicable. |
| Protective equipment | As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. |
| Further information | Dispose of fire debris and contaminated extinguishing water in accordance with official regulations. |
6. Accidental release measures
| Personal precautions | Spilled filament or pieces may cause a slipping hazard. Ensure adequate ventilation. |
| Environmental precautions | Do not flush into surface water or sanitary sewer system. Keep out of waterways. |
| Cleaning up | Pick up or sweep up and place in a suitable container for disposal. |
7. Handling and storage
| Safe handling | Use personal protective equipment. Avoid contact with skin and eyes. Low hazard for usual industrial or commercial handling. Workers should be protected from the possibility of contact with molten material during fabrication. Avoid dust formation. If small particles are generated during further procecssing, handling, or by other means, combustible dust concentrations in air may form. |
| Fire and explosion | Dust from grinding or sanding can form an explosive mixture with air. Take precautionary measures against static discharges. |
| Storage | Store at temperatures not exceeding 50 °C / 122 °F. Keep cool. No special restrictions on storage with other products. |
| Incompatibilities | Oxidizing agents, Strong bases |
8. Exposure controls / personal protection
| Exposure limits | None established. This material can generate Particulates Not Otherwise Classifiable (PNOC). The Occupational Safety and Health Administration (OSHA) PEL/TWA for PNOC is 15 mg/m3 for total dust and 5 mg/m3 for the respirable fraction. The American Conference of Governmental Industrial Hygienists (ACGIH) TLV/TWA for PNOC is 10 mg/m3 for inhalable particulates and 3 mg/m3 for respirable particulates. |
| Engineering controls | Provide exhaust ventilation if dust or fumes are generated during processing. |
| Personal protection | Engineering measures: Where reasonably practicable this should be achieved by the use of local exhaust ventilation and good general extraction. Provide appropriate exhaust ventilation at places where dust is formed. Eye protection: Safety glasses with side-shields. Goggles. Skin and body protection: Impervious clothing. Respiratory protection: Respirator must be worn if exposed to dust. Wear respirator with dust filter. Respiratory protection is needed if any of the exposure limits in Section 3 are exceeded. Consult an industrial hygiene professional prior to respirator selection and use. Use a postive-pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air-purifying respirators may not provide adequate protection. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres. Hand protection: Preventive skin protection. Hygiene measures: Avoid contact with skin, eyes and clothing. Special hazard: Workers should be protected from the possibility of contact with molten material during fabrication. |
| Hygiene | Do not eat or drink while working. Handle in accordance with good industrial hygiene and safety practice. |
