Wax-based 3D printing relies on a simple principle with demanding execution: paraffin or another printing wax is melted, delivered as a liquid and deposited with precision. The section between the wax reservoir and the print head is where things most often go wrong. If the wax cools on the way, it thickens, flow becomes irregular and the line can clog, interrupting the print. JINGCHENG's paraffin wax hose, also known as the 3D printer wax hose, is an electrically heated hose commonly used in 3D printing equipment, heat resistant up to 230°C. 3D printing is a young industry, and JINGCHENG's wax hose has been upgraded generation after generation together with customers' machine models and technology, reaching a very high degree of matching with the printers and very stable quality.
Wax solidifies quickly: a few degrees of cooling can turn liquid wax into a plug.
Viscosity drives print quality: stable wax temperature means stable flow and consistent deposition.
Small bores are sensitive: narrow delivery lines block faster when wax starts to set.
Machine uptime: a blocked line means cleaning, restart and lost build time.
The heating layer is made of uniformly braided heating elements that minimize the temperature difference along the inner wall, so the molten wax stays at an even temperature from inlet to outlet with no cold sections where it could set.
High-insulation-efficiency materials are selected with the outer surface temperature in mind. The printer spends less energy holding the line temperature and the hose surface stays safer inside the machine enclosure.
Because the hose has evolved with customers' printer models and technology upgrades, JINGCHENG can match length, bore, connectors and sensors closely to a specific machine, for both new designs and replacement parts.
A Type J or Type K thermocouple, Ni120, PT100 or PT1000 sensor can be integrated so the printer controller holds the wax at its set temperature.

Data source: JINGCHENG 2025 Electrically Heated Hose Catalog. Heat resistance up to 230°C; higher temperature on request. Confirm the rating at your operating temperature with our engineers when ordering.
Each JINGCHENG electrically heated hose is assembled to the buyer's specification. The catalog order form covers the following items:
Parameter | Options listed in the catalog |
|---|---|
Supply voltage | 380 Vac, 220 Vac, 110 Vac, 12 Vdc or other |
Temperature sensor | Type J thermocouple, Type K thermocouple, Ni120, PT100, PT1000 or other |
Hose length | 3 m, 4.5 m, 5 m, 6 m, 10 m or other |
Inner diameter | Φ8, Φ12, Φ16, Φ19, Φ25 mm or other |
Working pressure | 4 MPa, 10 MPa, 20 MPa, 35 MPa or other |
Heating power | 110 W/m, 150 W/m, 170 W/m, 200 W/m or other |
End fittings | US, British or metric threads, or other |
Wiring | Pin number, wire color and function at the controller end and the gun/tool end |
A typical code such as JCH-200-16-B-3X220-P2-8 is read as follows: 200 = working temperature 200°C; 16 = inner diameter Φ16 mm; B = inner tube type (B stainless steel corrugated tube, TB PTFE hose with stainless steel braid, T PTFE hose, X special material); 3X220 = supply (220 = 220 V single phase, 3X220 = three-phase four-wire 220 V); P2 = sensor (P2 PT100 two-wire, P3 PT100 three-wire, K Type K, J Type J, W no sensor, T special sensor); 8 = working pressure 8 MPa.
Ambient temperature -40°C to +55°C, relative humidity not above 85%
Atmospheric pressure 86 kPa to 106 kPa; voltage range 12 Vac to 380 Vac
No gases that corrode metal or damage insulation, no conductive media and no severe mold in the surroundings; other environments are handled as custom builds
Connect the hose strictly according to its technical data and the pin table delivered with it.
Never twist the hose sideways during or after installation; torsion can lead to leakage, flow loss, hose damage or fire.
Keep bends generous; over-bending can damage the hose and cause short circuit, leakage or fire.
Let only authorized, trained operators handle the hose, ideally a dedicated team.
Unauthorized modification or adjustment voids the warranty.
For any situation not covered by the instructions, contact JINGCHENG engineers for installation guidance.
Send your inquiry by phone, fax or the website inquiry form.
Our engineers confirm the most suitable specification as the basis for quotation.
You receive a quotation and confirm with a purchase order.
The hose is produced in our factory to the confirmed specification.
Every hose is inspected for defects and packed.
The order is shipped to your designated address.
Wax and set point: state the wax type and the temperature at which it must be delivered (standard up to 230°C).
Bore and length: choose an ID from 1/4" to 1" to suit wax flow, and measure the route inside the machine from reservoir to print head.
Electrical data: supply voltage, power per meter and the sensor type the printer controller reads.
Interfaces: thread standard at both ends (US, British or metric) and the connector pin assignment.
Installation: route the hose without twisting and keep bends generous, especially close to the fittings.
