Technical data sheet
Overview & applications.
WJ PC/ABS HX is a polycarbonate-ABS alloy filament. It brings together the stiffness and heat resistance of polycarbonate and the toughness and easier processing of ABS, with noticeably lower warpage than plain PC and better surface quality on large parts.
Typical applications
Automotive interior and functional panels – electronic device housings – structural parts needing both stiffness and impact resistance – medium-load mechanical parts – tooling, jigs and fixtures.

Technical data sheet
Data source & test conditions.
| Topic | Data source & test conditions |
|---|---|
| Data status | Typical reference values; not independently re-tested by WJ on this batch. |
| Test standards | ISO 1183 (density) – ISO 11357 (melting temperature) – ISO 75-2 (heat deflection and Vicat) – ISO 527 (tensile) – ISO 178 (flexural) – ISO 179 (Charpy impact). |
| Specimen orientation | X·Y: printed flat on the build plate. Z: printed standing upright so that the load acts across the layer stack. |
| Conditioning | Specimens conditioned to ISO 291, 23 °C / 50 % RH, before testing. |
| Printing conditions | Specimens printed with the parameters in Section 3: 100 % infill, three or more perimeters, 0.4 mm nozzle or larger. |
| Status of this sheet | Indicative. WJ is building its own test programme; values will be replaced with WJ in-house data as it becomes available. Contact us for the current status before design release. |
| Topic | Guidance |
|---|---|
| Typical, not minimum | Typical reference values for standard specimens under the stated conditions; not finished-part performance. |
| Orientation matters | Values marked X·Y apply to specimens printed flat on the build plate. Z values are measured on parts printed standing up and are typically lower than X·Y. Design for the direction that carries the load. |
| Reinforced grades are anisotropic | Fibre-reinforced grades show a larger X·Y to Z difference than unfilled grades. Where the Z value is much lower, orient the part so that the load runs along the layers. |
| Not a certificate | This sheet is not an inspection certificate, a Declaration of Conformity or a certificate of analysis. Batch-specific CoA, RoHS / REACH declarations and safety data sheets are issued separately on request. |
Technical data sheet
Storage, handling & safety.
| Topic | Guidance |
|---|---|
| Storage before use | Sealed bag with desiccant, 15 – 25 °C, below 50 % RH, away from direct sunlight and UV. Shelf life 24 months in the sealed bag. |
| Storage after opening | Engineering grades absorb moisture noticeably. Reseal with desiccant immediately after use and re-dry before critical prints: 70 – 80 °C for 4 – 6 h, or follow the grade-specific schedule in Section 3 where one is give |
| Symptoms of moisture | Popping and hissing at the nozzle, steam bubbles, rough extrusion, weak layer bonding and loss of impact strength. Dry the spool before changing any printing settings. |
| Nozzle wear | Carbon- and glass-fibre reinforced grades are abrasive. Use a hardened steel, carbide or ruby nozzle: a brass nozzle can wear out within a few hundred grams of reinforced filament. |
| Annealing | Where a grade is annealed (Section 3), move the print straight into a cold oven, ramp slowly, hold, then cool inside the oven. Never anneal filament on the spool – most spools deform above 90 °C. |
| Handling | Keep the spool on its holder and avoid sharp bends at the extruder inlet. Cut reinforced filament leaves sharp fibre ends – wear gloves when handling. |
| Ventilation | Printing releases a noticeable odour and measurable VOC, particularly with PA, PPA, ABS and PPS grades. Print under extraction or in a filtered enclosure. Not for use in enclosed occupied spaces. |
| Fire and disposal | Combustible solid. Keep away from open flame and hot surfaces. Spool, bag and carton are recyclable; offcuts are not biodegradable and should go to plastics recycling. |
| Personal protection | No special protection required for normal use. Wear gloves when handling hot parts or cut filament and safety glasses when cutting. Use an organic-vapour respirator for prolonged printing in a confined space. |

The data in this document are typical values obtained from tests on standard specimens as described in Section 5. They are provided for material comparison and selection only and do not constitute a specification, warranty or guarantee of performance. Properties of an actual printed part depend on printer hardware, slicing parameters, part geometry, build orientation, ambient conditions and post-processing. Fibre-reinforced grades are strongly anisotropic and must be qualified by the user for the intended load case. WJ reserves the right to amend this document without notice. The buyer is responsible for verifying that the material is suitable for the intended application, including any regulatory, electrical or food-contact requirement.
