3D Printing (Additive Manufacturing) Practice Test

The 3D Printing (Additive Manufacturing) Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests 3D printing and additive manufacturing knowledge — the seven ISO/ASTM process categories, design for additive manufacturing, materials and post-processing, and slicing, print quality and safety — written to ISO/ASTM 52900, SME additive manufacturing certification topics, NIST additive manufacturing research and NIOSH 3D printing safety guidance for 2026. Score 70% or more on its 20 questions to earn a verifiable 3D Printing Readiness certificate (SOA-3DP). Every question is based on published standards and research — including Additive Manufacturing Certification (Fundamentals and Technician) (SME), ISO/ASTM 52900:2021 Additive manufacturing – General principles – Fundamentals and vocabulary (ISO / ASTM International), Additive manufacturing research and standards (NIST) — and each answer is explained with its source.

Yes. Science of Apps has a free 3D Printing (Additive Manufacturing) Practice Test built on the current exam outline for 2026 and 2027. It covers processes and technologies, design for additive manufacturing, materials and post-processing and slicing, quality and safety, scores you instantly and issues a verifiable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a 3D Printing Readiness certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Additive Manufacturing Certification (Fundamentals and Technician) (SME); ISO/ASTM 52900:2021 Additive manufacturing – General principles – Fundamentals and vocabulary (ISO / ASTM International); Additive manufacturing research and standards (NIST); Additive manufacturing (3D printing) safety (NIOSH (CDC)). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Processes and Technologies (ISO/ASTM categories and Machines); Design for Additive Manufacturing (Overhangs, Orientation and Features); Materials and Post-Processing (Polymers, Metals and Finishing); Slicing, Quality and Safety (Slicer settings, Defects and Hazards). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

3D printing technician, Additive manufacturing engineer, Product designer, Maker-space or lab manager and Manufacturing engineering student. It suits anyone who wants a quick, verifiable way to show 3D Printing knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

ISO/ASTM 52900 groups additive manufacturing into seven categories: material extrusion (e.g. FDM), vat photopolymerisation (SLA, DLP), powder bed fusion (SLS, metal laser melting), material jetting, binder jetting, directed energy deposition and sheet lamination.

Design for additive manufacturing (DfAM) means shaping parts to suit how they are printed: limiting unsupported overhangs, choosing build orientation, setting wall thickness and clearances, and using freedoms such as lattices and part consolidation.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
