To avoid injuries it is necessary that the operator is aware of such situations and takes adequate care. It is the owners responsibility to ensure that every user of the 3D Printer is informed about risks and preventions and that the safety precautions are observed. Access to this manual must be provided at all times.\\ |
| - | The safety advices given in the following are meant to protect the operator of the HT500. It is the owner's responsibility to ensure that anybody working with or on the 3D Printer is familiar with this chapter and observes the given information.\\ | + | The safety advice given in the following is meant to protect the operator of the HT500.\\ |

| - | Inside the build chamber, the heating elements generate the necessary ambient temperature for warp-free printing.

| - | The extruder nozzles are heated to melt the filament strands and may **exceed temperatures of 300°C (572°F)**.\\ | + | The extruder nozzles are heated to melt the filament strands and may reach **temperatures of 500°C (932°F)**.\\ |
| - | Do not open the build chamber during or immediately after completion of a print job. The print table heating shuts down after finishing a print and cools down to chamber temperature. **Always wait** at least 10 minutes before removing the printed object. This is also to avoid stress cracks due to sudden temperature drop.\\ | + | \\ |
| - | If, for reasons of avoiding damage (e.g. collisions), it becomes necessary to interrupt the printing process and to open the build chamber before the cool down time has passed, **wear adequate protective gloves** when touching any interior. | + | Touching heated components may lead to grade 1 burning injuries, in case of the nozzles of grade 2 of limited size.\\ |
| + | \\ | ||
| + | To avoid burning injuries: | ||
| + | * **Do not open** the build chamber during or immediately after completion of a print job. | ||
| + | * **Always switch off** the preheating and wait until the print bed temperature indicated on the touchscreen has dropped below 50°C (122°F) before removing the print bed. This is also to avoid stress cracks due to sudden temperature drop. | ||
| + | * Some tasks require handling at operating temperature (e.g. changing the nozzle tip). **Wear adequate protective gloves** when handling hot components. | ||
| + | * Observe the procedures and waiting times stated in this manual. | ||

Always wear **adequate protective gloves** that are resistant to chemical substances (e.g. PVC, NBR).\\ | If it is necessary to perform works on the cooling system, such as refilling coolant or exchanging defective hoses, avoid direct skin or eye contact.

| + | === Noise === | ||
| + | The HT500 3D Printer is build to be operated in a professional environment such as workshops and laboratories. It is not suited for the operation in an office. During print jobs, it does not exceed 60dB(A), which is considered "unauspicious" for long-term exposure.\\ | ||
| + | Special noise protection equipment is not required. | ||
| + | |||
| + | === Fumes === | ||
| + | Molten plastics may emit unpleasantly smelling fumes. The HT500 3D Printer is equipped with an activated charcoal filter element to reduce such fumes. It is mainly to reduce smells and **does not** protect from toxic fumes that evaporate from overheated plastics. Such fumes can be **perilous**.\\ | ||
| + | It is vitally important not to exceed the temperature limits stated for a printed [[knowledge-base#materials|material]]. Overheating is indicated by discoloration and coking. | ||
