EU Declaration of Conformity for 3D Printers: requirements and checklist

By Ing. Jaroslav Křepelka, Owner, DoC solutions s.r.o. · Updated 29 October 2026

In short: A desktop 3D printer is declared under the Low Voltage Directive 2014/35/EU, the EMC Directive 2014/30/EU and the RoHS Directive 2011/65/EU, or the Radio Equipment Directive 2014/53/EU instead of LVD and EMC for Wi-Fi models. From 20 January 2027 the Machinery Regulation (EU) 2023/1230 expressly keeps "additive printing machinery" in its scope, unlike other office machinery, so 3D printers placed on the market from then need a machinery declaration as well.

3D printers sit on the border between IT equipment and machinery: they are mains-powered electronics with heated parts, but they also have motors that move the print head and bed. Until 2027 most desktop printers have been declared as electrical equipment; the new Machinery Regulation changes that.

This page covers desktop FDM (filament) and resin (SLA, MSLA) printers for consumer and prosumer use. Industrial additive manufacturing systems need a full machinery assessment and are outside this page.

Which EU legislation applies

Legislation	Applies?	In the DoC?	Notes
Low Voltage Directive2014/35/EU	Applies	In the DoC: Yes	Mains-powered printers and those with a mains power supply. Not cited separately for Wi-Fi models, where RED covers safety.
EMC Directive2014/30/EU	Applies	In the DoC: Yes	Stepper drivers, heaters with PWM control and switch-mode power supplies. Not cited separately for Wi-Fi models.
Radio Equipment Directive2014/53/EU	Depends on model	In the DoC: Yes	Printers with Wi-Fi or Bluetooth. RED then covers safety, EMC and radio, and printers that connect to the internet or a cloud service must also meet Delegated Regulation (EU) 2022/30 on cybersecurity since 1 August 2025.
RoHS Directive2011/65/EU	Applies	In the DoC: Yes	Restriction of hazardous substances in electrical and electronic equipment.
Machinery Directive2006/42/EC	Depends on model	In the DoC: Yes	Until 19 January 2027. Article 1(2)(k) excludes information technology equipment and ordinary office machinery insofar as they are covered by the LVD, and desktop printers have generally been treated that way. Assess and document your position.
Machinery Regulation(EU) 2023/1230	Applies	In the DoC: Yes	From 20 January 2027. Article 2(2)(p) excludes "ordinary office machinery, except additive printing machinery for producing three-dimensional products", which brings 3D printers placed on the market from that date into the regulation, with its essential health and safety requirements, risk assessment and machinery declaration.
Cyber Resilience Act(EU) 2024/2847	Depends on model	In the DoC: No	Connected printers are products with digital elements: vulnerability reporting from 11 September 2026 and full requirements from 11 December 2027.
WEEE Directive2012/19/EU	Applies	In the DoC: No	Producer registration in every EU country where you sell and the crossed-out wheeled bin symbol.

Typical harmonised standards

A harmonised standard gives presumption of conformity only in the version cited in the Official Journal of the EU. Always check the current list for each directive before you issue or update a declaration (European Commission: harmonised standards); the versions below are the ones commonly used at the time of writing, and the right selection depends on your product.

Safety

There is no dedicated harmonised standard for desktop 3D printers. Manufacturers usually apply EN 62368-1 for electrical safety and complete it with a risk assessment for the mechanical and thermal hazards, which becomes a formal requirement under the Machinery Regulation.

EN 62368-1Safety of ICT equipment (the LVD list cites the 2014 edition; the current edition is EN IEC 62368-1:2024 + A11:2024)
EN ISO 12100:2010Safety of machinery — general principles for design — risk assessment and risk reduction
EN 62471:2008Photobiological safety, for the UV light source of resin printers

EMC

EN 55032:2015 + A11:2020Electromagnetic compatibility of multimedia equipment — emission requirements
EN 55035:2017 + A11:2020Electromagnetic compatibility of multimedia equipment — immunity requirements
EN 61000-3-2:2014 and EN 61000-3-3:2013Harmonic currents and flicker

Wi-Fi models (RED)

ETSI EN 300 328 V2.2.22.4 GHz Wi-Fi and Bluetooth
ETSI EN 301 489-1 and EN 301 489-17 V3.3.1EMC standard for radio equipment — wideband data transmission systems
EN 18031-1:2024Cybersecurity for internet-connected radio equipment (cited with restrictions)

Hazardous substances (RoHS)

EN IEC 63000:2018Technical documentation for the assessment of electrical and electronic products with respect to the restriction of hazardous substances

Common mistakes in 3d printer declarations

No plan for the Machinery Regulation
3D printers placed on the market from 20 January 2027 fall under Regulation (EU) 2023/1230. Stock arriving in 2027 needs a machinery declaration, a risk assessment and instructions that meet the regulation.
Hot and moving parts not addressed
Hot ends above 200 °C, heated beds and moving axes are the main hazards. Enclosures, interlocks, warnings and thermal-runaway protection in the firmware belong in the risk assessment.
Thermal runaway protection missing
A failed thermistor can let the heater run unchecked and cause a fire. Firmware protection should be enabled and documented in the technical file.
Resin printer UV and chemical hazards ignored
Resin printers need a photobiological assessment for the UV source and instructions on handling resins, which are classified chemicals with their own labelling.
Wi-Fi models declared under LVD and EMC
A printer with Wi-Fi is radio equipment: RED applies instead, with its radio standards and, for cloud-connected printers, the cybersecurity requirements.

What you need besides the declaration

Technical documentation: Safety, EMC or radio test reports, the risk assessment for mechanical and thermal hazards, the firmware safety functions, and RoHS documentation. Keep it for 10 years.
Instructions: Assembly, safe operation, ventilation and maintenance instructions and safety warnings in the language of each EU country where the printer is sold.
Economic operator in the EU: An importer, authorised representative or responsible person established in the EU (Article 4 of Regulation (EU) 2019/1020).

Frequently asked questions

Is a 3D printer machinery under EU law?

From 20 January 2027 the Machinery Regulation (EU) 2023/1230 expressly keeps additive printing machinery in its scope, so 3D printers placed on the market from that date need a machinery declaration. Before that, desktop printers are usually declared under the LVD and EMC Directives.

Which safety standard applies to a 3D printer?

There is no dedicated harmonised standard. EN 62368-1 is usually used for electrical safety, completed with a risk assessment under EN ISO 12100 for mechanical and thermal hazards.

Does a Wi-Fi 3D printer need the RED cybersecurity requirements?

If it communicates over the internet, for example with a cloud printing service, yes: Delegated Regulation (EU) 2022/30 has applied since 1 August 2025.

What does MyCECheck check on a 3D printer declaration?
