How to learn 3D printing: plain explanations, a study path and a test
Ask about 3D printing and manufacturing: what infill is, how FDM differs from SLA, where to start. The AI assistant EDi Mentor explains in short sentences, gives the exact term and is told to test you with one question. Ask how to learn and it is told to build a study path as a PDF. Its screen and answers are in Bulgarian.

What a personal 3D printing tutor is
How to learn 3D printing depends on where you are and what you want to print. EDi Mentor is an AI assistant on EduFacturing for students and beginners: it explains manufacturing technologies in plain words, gives the exact term and tests you, and when you ask how to learn, it builds a study path.
The mentor is told to rely on the EDi Brain knowledge base and to look up specific numbers in the EduFacturing rules; like any AI assistant it can be wrong. Of the 54 assistants it is the cheapest: one question costs 2 credits, and the next one up costs 5.
It is part of Ultra: at most 750 questions a month if you spend no credits on other assistants. If a run fails, the credits are returned.
What the mentor does when you ask
Explains simply, then gives the term
Short sentences, an everyday example and then the exact term, in Bulgarian and English in brackets.
Tests you with one question
The mentor is told to end the explanation with a control question for you, unless you asked otherwise.
Builds a study path as a PDF
When you ask what and how to learn, the assistant is told to make a PDF: topics in order, why each is needed, how many minutes it takes and a total in hours, up to 20 steps.
Makes a quiz with a key
When you ask for a quiz the assistant is told to make a PDF: up to 25 questions, up to six answers per question and the right answers at the end.
When to learn 3D printing with a mentor
The mentor helps when you learn alone and have nobody to ask.
A student or a beginner with a printer
Examples from the screen, in Bulgarian: what infill is and why it is not 100%, and how FDM differs from SLA.
Someone looking at manufacturing
An example from the screen: why metal parts are cast rather than always milled.
A parent or a teacher
A self-check quiz and a study path for home. For a whole class lesson there is EDi Classroom.
When you want a study plan
You ask how to learn; the assistant is told to make a study path as a PDF that you tick off topic by topic.
Where the mentor gets its knowledge and numbers
The mentor is told to take topics from the EDi Brain knowledge base and numbers from the EduFacturing rules.
It searches EDi Brain
The mentor is told to explain on top of the knowledge base about technologies, materials and manufacturers, not from memory.
It takes the numbers from the rules
When a specific number or rule is needed, it is told to look it up in the EduFacturing rules.
It leads step by step
It is told not to hand over homework answers: to lead you towards the answer and end by asking you.
It tests you and is told not to do your homework
It leads you, it does not do your homework
The assistant is told to lead you step by step towards the answer.
It tests, it does not only talk
The assistant is told to end with a question, and the quiz has a key at the end.
The cheapest assistant
Two credits a question, while the next one up of the 54 assistants costs five.
The mentor is not a video course with grades. It does not track your progress: the study path is a PDF that you tick off yourself, the times in it are a guide and the links to lessons are not checked automatically. The assistant is told not to hand over homework answers. For some answers it also makes a reference sheet (“Spravka”) as PDF and CSV: it is signed EDi Engineer Reference (in Bulgarian) and carries an engineering note.
The answers are written by AI and may contain mistakes: check what matters. The screen and the answers are in Bulgarian. Files are deleted after 24 hours.
Questions about how to learn 3D printing
How to learn 3D printing?
Ask the assistant how to learn from scratch. It is told to make a study path as a PDF with topics in order, a reason and minutes for each, up to 20 steps. Then you ask about each topic.
What is infill in 3D printing?
Infill is what fills the inside of a printed part, set as a percentage. The mentor explains why it is usually not 100%, in plain words, gives the term and is told to ask you one question.
How to get started with 3D printing?
Tell the assistant what you have and what you want to print. It explains step by step and is told to ask a control question; it looks up numbers and limits in the EduFacturing rules.
Does it work in English?
No. The screen and the answers are in Bulgarian. In a test on 10.10.2026 an English question to another assistant, DFAM, also got a Bulgarian answer.
