What Microjet does

Microjet (株式会社マイクロジェット) is a privately held Japanese company specializing in industrial and life-science applications of piezoelectric inkjet technology. Founded in the Nagano Prefecture (HQ in Shiojiri) with a Tokyo sales branch in Kokubunji, the firm markets picoliter-to-nanoliter liquid dispensing systems built around two proprietary head families: the in-house GlassJet glass-and-PTFE single-nozzle heads (CV under 2%, viscosities 0.5-150 mPa·s, surface tensions up to 73 mN/m) and the PipeJet disposable nanoliter heads sourced from Hamilton under what appears to be an exclusive Japanese arrangement. These heads feed a broader catalog of complete systems grouped by application: printed-electronics (LaboJet, NanoPrinter, DevicePrinter, PerovsJet for perovskite solar cells, Perovsprinter), biotechnology (LaboJet-Bio, LaboJet-2000Bio, BioSpot, BioSpot Arc, NanoJet, x.sight single-cell dispenser, b.sight bacterial dispenser), 3D printing (MateriART binder/material jetting), and droplet-observation peripherals (DropMeasure, JetScope, IJK, PJK) plus support modules (IJH, PJH head units, CLEANJECTOR cleaning system, SF-100STC/SF-400/MSF pressure controllers, INKTESTER DIGITAL, HCL1).

Microjet's revenue model blends hardware sales (inkjet heads, complete systems, peripherals, JetMeasure software) with high-margin technical services — head selection, ejection evaluation, prototype drawing, droplet observation, equipment rental, and consulting — complemented by InkJet Academy seminars, white papers, and specialized technical books. Customers are primarily Japanese industrial R&D organizations and academic institutions, with five named university/governmental lab references (AIST, Shinshu University, University of Tsukuba, Kobe University, Hokkaido University) representing published research collaborations rather than disclosed commercial volume. The company pursues a sales-led direct engagement model via its website (catalog requests, demos, quotations) and distributes the Spanish-made CLEANJECTOR cleaning system in Japan on an exclusive basis.

Leadership is anchored by founder/CEO Shuichi Yamaguchi, who holds a PhD in engineering and serves concurrently as representative director of 3D Printer Soken and board member of Japan 3D Printer Association — embedding Microjet in Japan's specialty inkjet and additive-manufacturing ecosystems. The firm is independently owned with no disclosed external funding, parent company, or acquisitions, and reports no AI/ML strategy beyond classical image-processing-based droplet measurement automation.

Core offering

Microjet designs, manufactures, and sells proprietary piezoelectric inkjet heads (GlassJet picoliter glass nozzle series and PipeJet nanoliter disposable resin series) along with complete inkjet systems for printed electronics (LaboJet, NanoPrinter, DevicePrinter, PerovsJet), biotechnology (LaboJet-Bio, BioSpot, x.sight, NanoJet), droplet observation (DropMeasure, JetScope), and 3D printing (MateriART). The company also provides technical services including head selection consulting, ejection evaluation, drawing/prototyping experiments, equipment rental, and training seminars.

Product overview

Microjet is an inkjet technology R&D partner specializing in industrial and life science applications of piezoelectric inkjet technology. The product portfolio is organized into two main axes: (1) Single-nozzle and multi-nozzle inkjet heads (GlassJet glass nozzle heads for picoliter dispensing with high chemical resistance, and PipeJet disposable nano-liter heads from Hamilton), and (2) Complete inkjet systems categorized by application domain — Printed Electronics (LaboJet, NanoPrinter, DevicePrinter, PerovsJet, Perovsprinter for perovskite solar cell and electronic device coating), Biotechnology/Bio-LS (LaboJet-Bio, LaboJet-2000Bio, BioSpot, BioSpot Arc, NanoJet, x.sight single-cell dispenser, b.sight bacterial dispenser), Droplet Observation (DropMeasure, JetScope, IJK, PJK, JetMeasure), and 3D Printing (MateriART). Supporting peripherals include head controllers (IJH, PJH), cleaning systems (CLEANJECTOR, HCL1), pressure control units (SF-100STC/SF-400/MSF), and the INKTESTER DIGITAL printing evaluation system. The company also offers technology services (head selection, ejection evaluation, drawing/prototyping, droplet observation, equipment rental, consulting) and professional seminars/training programs.

Direct peers

• Xaar: UK-based manufacturer of industrial piezoelectric inkjet printheads for graphics, packaging, ceramics, and 3D printing. Direct head-to-head competitor to Microjet's GlassJet/PipeJet lines in industrial dispensing applications.
• Fujifilm Dimatix: Industrial inkjet printhead and system manufacturer (subsidiary of Fujifilm) serving printed electronics, photovoltaics, and life sciences. Highly comparable to Microjet's printed electronics and biotech inkjet systems.
• Microdrop Technologies: German specialist in piezoelectric drop-on-demand inkjet heads and dispensing systems for industrial, biotech, and microdosing applications. Closest peer in scale and niche specialty positioning.
• SCIENION: German specialist in piezo-based ultra-low-volume dispensing for diagnostics, life sciences, and microarrays. Directly competes with Microjet's BioSpot, x.sight, and b.sight biotech product lines.
• TTP (The Technology Partnership): UK-based technology developer of precision inkjet and microfluidic dispensing systems including the LabTech and Fluidicent product lines for life sciences and industrial applications.

Broad incumbents

• Konica Minolta (Industrial Inkjet): Major Japanese conglomerate with an industrial inkjet printhead business (Konica Minolta IJ Technologies). Competes with Microjet in industrial heads but as part of a much broader imaging and healthcare portfolio.
• Ricoh (Industrial Inkjet): Japanese conglomerate with industrial inkjet printheads (Ricoh Industry) and additive manufacturing offerings. Comparable head technology but competing from a much larger diversified base.
• Stratasys: Large public 3D printing OEM with material jetting and PolyJet technologies. Comparable to Microjet's MateriART binder/material jetting 3D printer, but competing at vastly different scale.

Others

• Hamilton Company: US-based manufacturer of precision fluid handling whose PipeJet technology Microjet distributes in Japan as its disposable nanoliter head. Supplier and technology partner rather than competitor.

Emerging players

• Arrayit Corporation: Smaller US-based microarray and inkjet-based diagnostic platform company. Partial overlap with Microjet's bio-dispensing applications but at a different scale and life sciences focus.
