Active listening is not just about hearing, but also about showing and expressing that you are listening. To practice active listening for 3D printing, it is important to prepare by being in a quiet and comfortable environment free from distractions and interruptions. Additionally, it is important to be open-minded and curious about the other person's perspective and experience. While the other person is speaking, focus on their words, tone, and body language. Avoid interrupting, judging, or jumping to conclusions. Instead, use non-verbal cues such as nodding, smiling, or leaning forward to show your interest and attention. After the other person finishes speaking, ask open-ended questions to check your understanding and to encourage them to elaborate or explain. You can also paraphrase or summarize what they said to confirm or correct your interpretation. Once you have clarified the message and the emotions of the other person, you can express your own thoughts, feelings, and needs in a respectful and constructive way. Additionally, you can offer suggestions, solutions, or compromises if appropriate to resolve the 3D printing issue or to move the project forward.
