House interior details

Manufacturer of interior details sent a few different designs to print to have a better view and feel for further manufacturing decisions.

Wall clock designs were printed on a large-scale 3D printer which is based on FDM technology. PolyMax PLA material was chosen specifically for its ease to print and very similar properties to ABS plastic. Handles were printed on "Zortrax M200" machines with HIPS plastic because of its impact resistance and easy to post-process.

Whole printing project took only 2 working days with 4 different wall clock designs and more than 20 knobs. The duration of printing shows very good opportunities with additive manufacturing for quick pre-manufacturing processes to determinate compatibility and design choices.

3D printing material: PolyMax PLA and HIPS

3D printing technology: Fused Deposition Modeling

Product size (mm): clocks up to 260 x 260 x 30 / knobs up to 30 x 30 x 60

 

Mandible guides

By medical institution's inquiry, specific lower jaw guides were printed for pre-operation purposes.

By surgical team needs, fully functional 3D models were modeled by engineer using computer tomography images. Created 3D models were printed using state of the art SLS 3D printer which is widely considered one of the best 3D printing technologies to produce high complex, accurate and very strong parts. Because of the plastic powder base, support requirement is compeltely eliminated and because of the said purpose, guides were printed using medical grade nylon (poliamide) plastic material.

Industrial grade SLS 3D printing technology has almost no design limitations and is a great option to produce complex, unique, small series parts considering high need of accuracy, surface quality and strength.

3D printing material: PA2200

3D printing technology: Selective Laser Sintering

Product size: ~ 150 x 150 x 80

 

3D scanning of impellers

According to the customer's order, we made impellers 3D scanning. The scan was made using an extremely accurate Artec Space Spider 3D scanner capable of scanning up to 0.05 mm. Despite the thin-walled nature of the wings, the final result of the model was particularly precise and detailed.

The scanned files have been used by the customer for reverse engineering processes that allow computer-controlled adjustment, product development, and the development of impellers production projects. 3D scanning accelerates the duration of the creation of computer models and the accuracy of these models because drawing a manual measurement of such a product would be very long, difficult and imprecise process.

Object size (mm): 135 x 65 x 55; 150 x 85 x 65;

Metal Gear Wheel

The client contacted us, having worn gear wheel with weary gear teeth. At his request, we restored and printed a new metal gear wheel.

First of all, the recovery of the gear wheel was carried out using 3D modeling software. The gear wheel has been measured and accurately restored to the relevant standards. Since the original part was made of metal, the printing of the plastic, in this case, did not fit, because the part was supposed to be extremely strong. For this reason, we chose stainless steel for printing. The printed metal gear wheel in the mechanism has completely replaced the worn-out old gear wheel.

Since such gears are usually sold in a complete set with the whole mechanism, its acquisition from trading venues is really expensive. In this case, 3D printing allowed the customer to quickly and with low cost get the necessary part without much effort.

3D printing material: Stainless steel

3D printing technology: DMLS (Direct Metal Laser Sintering)

Product size (mm): Ø25 x 6.8
