About

Additive Days is an initiative created by B2N with the mission of promoting additive manufacturing and showing its potential in industry, science, education and society.

Over the years the event has established itself as a platform for exchanging knowledge, presenting innovation, and bringing together business, academia and the professional community.

The mission

To show the potential of additive manufacturing across industry, science, education and society.

Initiator

B2N created Additive Days in 2018 and has organised every edition since.

Additive Days is our platform for promoting the latest trends and possibilities in the world of 3D technologies. Through the event we want to bring the audience together with engaging speakers and real stories, to show valuable applications of 3D printing, and to share hands-on experience from the industry. Our main goal is not simply to present technologies, but to build and unite a community of people and companies working with innovation, 3D technologies and additive manufacturing.

FAQ

01 What is Additive Days?
Additive Days is an international 3D printing and additive manufacturing event — a conference, exhibition, expo zone and workshops, held in Sofia since 2018. It exists to show what the technology actually does in industry, medicine, architecture, education and art. It is created and organised by B2N, the official representative for Bulgaria and the Balkans of leading additive manufacturing companies.
02 When and where is the next edition?
The fifth edition is in preparation for 2027 in Sofia — dates, venue and programme will be announced on the site and in the newsletter. The fourth edition took place on 10 September 2026 at Sofia Tech Park, as the additive manufacturing zone within Robotics Strategy Forum 2026, in collaboration with BAMAS.
03 Is there an entry fee?
No — entry is free. Registration is required, though, because seats in the hall and in the workshops are limited. Register in advance to secure a place and receive the programme by email.
04 How do I register?
Through the registration page — enter your name and email and you will get a confirmation. If you prefer, simply write to hello@additivedays.com.
05 Who is the event for?
Engineers, doctors and dental technicians, architects, designers, entrepreneurs, teachers and students — and anyone curious about what can be built layer by layer. The programme deliberately mixes industrial applications with medicine, education, architecture and art, so it rewards both the specialist and the newcomer.
06 What does the programme include?
Four things that run together: talks by Bulgarian and international specialists, an expo zone where manufacturers show machines and materials live, an exhibition of objects printed by authors and studios, and hands-on workshops. The exact 2027 programme is announced ahead of the event.
07 What language are the talks in?
The programme is bilingual — talks are given in Bulgarian or English, with the language marked per session. Several speakers come from abroad, so English is common for the international sessions. The site itself is bilingual too.
08 How do I become an exhibitor or partner?
Write to hello@additivedays.com with a short description of your company and what you would show. The expo zone has hosted up to 13 exhibitors in a single edition, among them Ultimaker, Formlabs, BigRep, Raise3D, Artec 3D, MarkForged and Altair, while partners include EOS and Meltio.
09 What happened at the previous editions?
Four editions so far. 2018 — the first Balkan 3D printing conference: 36 speakers from 11 countries, 13 exhibitors, 8 workshops, the "3D Happiness" exhibition with 17 authors, and 450 visitors. 2020 — "Beyond the hype": 22 speakers from 10 countries, 13 workshops, 11 exhibitors and 700 visitors. 2025 — a mini edition at Sofia Tech Park with over 1,000 visitors. 2026 — the additive manufacturing zone within Robotics Strategy Forum, in collaboration with BAMAS, with an expo of 9 partners, a forum lecture and around 200 visitors.
10 Who organises the event?
B2N created Additive Days in 2018 and has organised every edition since. In 2026 the edition was realised in collaboration with BAMAS, within Robotics Strategy Forum.
11 How do I get to Sofia Tech Park?
The event address is 111 B Tsarigradsko Shose Blvd, Sofia — the campus is reachable by car and by public transport heading towards Mladost / the airport. The Contacts page carries a map you can start navigation from directly.
12 Is it suitable for children and families?
Past editions have had a kids programme — in 2018 the eight workshops included ones for children and teachers, and in 2020 the kids programme ran with SteamPowered. Whether 2027 carries a separate kids programme will be clear when the programme is announced, but the expo zone and the exhibition are engaging at any age.
13 Will there be materials after the event?
Yes. Photos, highlights and press coverage from each edition are collected in the site archive — the galleries from 2018, 2020, 2025 and 2026 are already there, along with the brochures and the media coverage.
14 How do I follow the news?
Subscribe to the newsletter in the footer — we send the programme, the speakers and the practical details, without spam. The site can also be installed as an app on your phone or computer from the footer button, so it stays one tap away.
