The collection of industrial design at Museum of Architecture and Design is extremely diverse. It contains practical and decorative items made of different materials, from textile, wood and metal to glass and various artificial materials. They were made for very different purposes: electronics, health industry, room furnishing, sports, games, public spaces, and other. Products associated with successful Slovenian companies and with the development of modern industrial production in Slovenia are particularly outstanding. Companies such as Stol, Iskra, Gorenje, Rogaška, Steklarna Hrastnik, Dekorativna and Elan have significantly influenced the development of design in Slovenia and, consequently, enforced notable designer names.

Among prominent designers represented in the collection there are the fathers of Slovenian design: Albert Kastelec, Oskar Kogoj, Niko Kralj, Janja Lap, Slavko Marcen, Saša Mächtig, Ferdo Pak, Davorin Savnik, Branko Uršič, Dušana Uršič and others. These are followed by the middle generation with Vladimir Pezdirc, Igor Rosa and Janez Smerdelj. Among the representatives of contemporary design production, we find the Gigodesign company, Bojan Klančar, Jure Miklavc and Rok Oblak. Museum of Architecture and Design takes special pride in beautifully designed microphones, tape recorders, oscilloscopes and other electronic devices designed by Mark Turk, an exceptional designer in the field of electro-acoustics. In 2009, the museum also acquired a large collection of Iskra phones, counters, radio and television sets, small household appliances, hand tools and similar items with an organized campaign to collect items produced by Iskra.

In addition to Slovenian products, the collection is regularly updated with items participating in the Biennial of Industrial Design. The international event, organized by the museum for almost 50 years, has enriched the collection with names such as Ron Arad, Konstantin Grcic, Karol landlord, Marina Paul, Judith Rataitz and Richard Sapper, and company names such as Alessi, Authentics, Zanussi, Lamy, Rodenstock and many others.

Biennial of Industrial Design (BIO) is one of the few international design events which has been promoting contemporary trends in international design with a selection of well-designed products since 1964. Due to the initiative of professional organizations and individuals, BIO was founded in 1963 by former City Council of Ljubljana, Chamber of Commerce of Slovenia and The Cultural Assembly of Slovenia, and a year later the first exhibition BIO 1 was held. The Biennial has been a part of the Museum of Architecture and Design since its creation in 1972.

Museum of Architecture and Design is the only institution in Slovenia that holds a collection of visual communications. The collection began to take shape at the launch of the museum in 1972 and now comprises about 9,000 units. It consists of posters, books, catalogs, magazines, newspapers, annual reports, brochures, corporate identity, calendars, signs, information graphics, packaging and other printed matter. Among the 340 designers there are Janez Trpin, Peter Kocjančič, Grega Košak, Jože Brumen, Majda Dobravec, Uroš Vagaja, Matjaž Vipotnik, Janez Suhadolc, Jani Bavčer, Kostja Gatnik, Miljenko Licul, Ranko Novak, Novi kolektivizem, Luks studio in and various younger creators. We can also find international authors such as Ivan Picelj, Dalibor Martinis, Boris Bučan, Shin Matsunaga, Per Arnoldi, Giovanni Pintori, Paul Rand and others.
