How To Identify The Quality Of 3D Printing Supplies

The following is the material experts for the development of 3D printing materials and summarizing the experience constantly, now share out so that we learn to adopt:

3D printing supplies is the following several major quality problems exist:

A, raw material quality; fluidity and viscosity are two main indicators; second is the raw material is in the process of occurrence of some chemical changes.

Two, the accuracy of consumables. Mainly supplies can be controlled within the range of tolerance.

Three, whether the material containing impurities.

The user is not a professional, to identify material mainly from the following aspects to observe.

A naked eye

1.1 please open the seal, carefully observe the supplies if there is a difference, the color is uniform;

1.2 careful observation, now if there are tiny bubbles inside;

1.3 if supplies are transparent, please carefully observe the material color is uniform; generally uneven color, that it supplies some changes have taken place in the production.

1.4 wire are black or any other color spots magazine. Eye is the most basic foundation, after small Ge suggest that you learn advanced skills to understand the accuracy of reason even the same 3D printer also can greatly improve the accuracy of the problem.

Two, precision

The test precision of 2.1 hand. Open 1-2 meters long supplies, with the thumb and index finger gently pinching supplies, then slowly to boost supplies. If there is uneven thickness or material material surface is not smooth, feel is very easy to perceive.

2.2 test instrument. Using vernier caliper to measure the digital display, multi position measurement is in the range of tolerance control in.

2.3 measurement methods. The measurement of 1-2 meters in length, diameter tolerance test is uniform; in each test point, range of rotation measurement 3-4 circle, the main wire, whether "circle", namely: whether effective control of wire diameter.

Three, to observe the quality of printing supplies

3.1 to observe the uniformity of substrate print lines. A general printer in print began to do the uniform degree of the nozzle in the observation of substrate, substrate. In general, more uniform, supplies precision control in the range.

3.2 sound judgment. If the supplies in normal operation, the gear feed supplies, if uneven, it will issue a "hanghang" sound.

3.3 printing consumables quality judgment. Observation of printing consumables in the internal structure of the uniform degree. Whether there are bubbles, spots and other issues.

3.4 viscosity judgment. Supplies must have viscosity in the printing process, or print will crack or break off phenomenon. Considering many kinds of material supplies, printer materials are different, there will be incompatible phenomenon. In order to ensure the smooth printing, the best on the substrate coated with some glue. Otherwise, because the printer in the printing process and the model of friction and collision caused by interruption of print.
