The world of materials for 3D printing has grown huge, as has the growing global catalog of transformative innovations that we are now gifted with. And while there are many different filaments and alternative sources to draw from, there are just as many problems, concerns, and drawbacks that are specific to each project, printer, and user.
Companies like Taulman3D specialize in helping users do something simple: create more 3D printed things – right. However, they provide us with a huge amount of information on the go, and it’s always a highlight when one of their new products shows up – which is quite common compared to other manufacturers.
Founded by Thomas Martzall, the filament manufacturing company consists of a team that is knowledgeable about materials and chemicals and continues to strive for new innovations and horizons for filaments, each with unique characteristics suitable for a wide variety of users looking for specific ones Elements for their own requirements.
Taulman is currently announcing the release of TECH-G, a PETG filament designed to provide even higher strength with limited elongation.
PETG filaments are becoming increasingly popular and are a modified version of the simpler PET, a non-toxic thermoplastic polymer resin used to make clothing and products such as containers. PETG filaments are an attractive and viable option because of their low melting temperature and their durability and flexibility in the finished state. PETG is a good alternative to ABS or nylon and usually offers transparency as well.
While PLA and ABS have traditionally been used, and especially by engineering firms, for “initial form and fitness assessments”, the Taulman team was aware that the overall strength of these filaments would limit the usefulness and potential of 3D models many times over.
“In the case of PLA, it was the brittleness of medium-sized or larger parts that severely restricted the functional test,” explains the Taulman team. “With ABS, the limit has always been tensile strength.”
TECH-G technical data for 3D printing:
- Tensile Strength – 5,900+ PSI
- Elongation – 3%
- IZOD notch – 2.14 ft-lbf / in
- Color – clear (colorless without added coloring)
- Odors – none
- Transmission – 90%
- Printing temperature – 235 ° C – 240 ° C.
TECH-G is a clear, odorless virgin polymer found in standard 1kg spools. It is available in both 1.75mm and 2.85mm sizes. In fact, almost as transparent as T-glass we reported on earlier in the year, this is a material known as co-polyester. The Taulman team suggests several tips for using with TECH-G, such as:
- Users should use lower fans when printing PLA polymers
- The best printing surface for a glass finish is printing on heated glass at 72 ° C.
- For a quick release bed, users should wipe a glass heated to 45 ° C with 50% PVA and 50% water
- Print temperatures vary slightly with nozzle size, but the average is 238 ° C.
- If too much is printed at too high a temperature, bubbles will appear in the printed thread, and if too cold the thread will appear cloudy
Earlier this year, TECH-G was released in a test phase where users can try it out and give Taulman feedback on its performance. After its release, Taulman sees TECH-G as a new and easier to use material for 3D printing. It offers higher tensile strength and just the right stretch for functional tests. TECH-G is FDA compliant with CFR 177.1315.
