Institute of Technology Carlow Students Build Prototype F1 Racecar

Car manufacturing is probably the most machine intensive industry out there. Naturally, this makes it an ample space to tinker with 3D prints and designs. In that same vein, students at the Institute of Technology Carlow have developed a prototype F1 car using a combination of CNC machining and 3D printing. The students built the prototype under the tutelage of Dr Cathal Nolan, a mechanical engineering lecturer.

The team itself is comprised of 3rd year mechanical engineering students. They divided themselves up into various sub-groups based on the core components of the design. Design elements included chasis, suspension, braking system and the body. Aside from the printers and the CNC devices, the students also had access to Solid works and Ansys CAD tools.

The students hope to enter their design in UK`s Formula Student competition. As part of the competition, they will showcase their design to a hypothetical manufacturing firm. Generally, Formula Student cars are capable of achieving an acceleration of 60 mph in 3.5 seconds. While no exact specs for this car were available, it must be capable of similar speeds if they hope to enter it into the competition.

Another group of students from TU Darmstadt 3D printed their new design for the same competition. They are using a specialised aluminum alloy to make the model 50% lighter than their previous ones. Over 600 universities are participating in the Formula Student competition. It is only natural that multiple universities are employing AM tech in their projects.

We`ve previously covered some of the most interesting ways 3D printing and cars have found common ground. Even though this is an emerging phenomenon, 3D printing and cars will no doubt be ubiquitous in due time. Generally, firms print parts of cars and assemble them as opposed to 3D printing the majority of the car.

At this stage, fully 3D printed cars are a niche phenomenon, although they do exist. Examples in the F1 circuit are rarer but 3D printers do provide certain coveted parts.

Fully 3D printing a car may not be that far off but there are certain criterion the technology needs to meet before this is feasible. The main obstacles to further implementation arise from build-space issues and developments in metal printing. Till such time, 3D printing will remain relegated to producing bits and pieces.

UHMW-PE Plastic Rod

UPE plastic,full name UHMWPE (ultra high molecular weight polyethylene) is a kind of thermoplastic engineering plastic with excellent properties of linear structure, with a molecular weight of more than 1.5 million.mainly have ESD UPE SHEET,CONDUCTIVE UPE.

Small density, good wear resistance, self - lubricity, impact resistance, corrosion resistance and so on.

Advantages:

1. Average molecular weight about 5,000,000 to 9,000,000;

2.The best abrasive assistance of all plastics , which 4 times higher than that of nylon 66 or teflon and 6 times higher than that of carbon steel;

3.Extremely high impact stength ,which is twice as high as PC ,5 times as high as ABS,it also retaines high toughness at liquid nitrogen temperature (-196'C);

4.Low friction coefficient ,lubricity is equal to that of Teflon ;

5.The best impact energy absorption value of all plastics ,with very good sound reduction effect ;

6.High chemical stability ,capable of resisting various types of corrosion and organic media within certain temperature and concentration range;

7.Strong adhensive resistance which is only second to Teflon;

8.UHMW-PE Plastic is safe , healthful and non-toxic and be can used in contact with food and drugs ;

9.Low density than any other thermoplastic ;

10.Excellent electrical insulation and static resistance ,good resistance to high energy radiation;

11.Moderate mechanical strength,stiffness and creep-resistant property'

12.Outstanding machining property ,very low water absorption .


Deficiencies:

Compared with other engineering plastics, UHMW-PE Plastic is resistant to heat resistance, stiffness and hardness, but can be improved by means of "filling" and "crosslinking".

From the point ofheat resistance, the melting point of UHMW-PE Plastic is approximately the same (136 ℃) and ordinary polyethylene, but because of its big molecular weight, melt viscosity high, so the processing difficulty is big.

Applications:

Papermaking industry : suction box boards ,scrapper,molding plate ,beating ,gear .

Mining industry : charging barrel ,abrasive and adhensive -resistant back lining for warehouses.

Chemical industry : acid pump ,fliter plate , worm gear ,bearing .

Food industry :packing machinery parts ,bottle guide ,screw .wear plate ,slide away ,stud weld ,roller and other transmission parts.

Tenxile industry : buffer board

Food processing industry : chopping block ,refrigerating plant

Wharf:anti-collision board

Specification: the thickness of UHMW-PE Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width can exceed 1200mm, and the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 600mm* 1200mm, and the commonly used specification of 10-180mm is 1200*3080mm. UHMW-PE Plastic can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.

Color: Black and white, can also be made another color, and the color order is 500KG.


Modified varieties: UHMW-PE Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.

Product certification: most environmental certification reports and safety reports forraw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
