FDM for Injection Moulding

“The FDM mould allowed us to get injection moulded parts in days rather than weeks. This is critical in our industry where the next race meet acts as our testing ground and marketing arena. “
Ken Nunn, Southways Consulting

The Project: This High Performance Throttle Body Adaptor is designed for use in high performance vehicles and must be injection moulded in order to fulfil its design requirements. An FDM injection mould allowed several shots to be produced while waiting for the CNC tool.

The Client: VCM Suite Australasia Pty Ltd ( manufacture software systems for the home and professional workshop for use in the high performance tuning of a range of vehicles.

The 3D Printing Process: Tooling and injection moulding has traditionally been a time consuming and expensive exercise; however if you need an injection moulded part in a hurry, FDM can help. FDM moulding is cost effective, fast and completely repeatable. Instead of machining a mould out of Ureol, aluminium or steel, a mould is created with Fused Deposition Modelling (FDM) at technology.

“We built to mould in ABS M30 which was then treated to make it suitable for high pressure plastic injection moulding,” says Simon Bartlett, Engineering Manager Objective3D. “Polyurethane was then injected into the mould with complete success. The FDM ABS-M30 mould was used over 30 times with no loss of quality. If the mould had been built out of Polycarbonate, even more shots would have been resourced from this fast, and inexpensive mould.”

The benefits of this type of tooling could completely revolutionise the prototyping industry, by reducing time to market and tooling costs. See Table for more details.

While further trails are needed to accurately compare the various tooling methods and to test the true limits of this type of FDM mould (in ABS and PC), the projected savings (both time and financial) makes this a process that could save companies thousands of dollars during the Research and Development phase of their project.

“FDM moulding allowed us to dip our toes into the market without the costly spend,: said Greg Brindley, Director, VCM Suite Australasia Pty Ltd. “We discovered that the market was larger than we expected and that the part was accurate and required no modifications. For only a minimal spend, we had parts in days and it gave us the confidence to proceed.”

“The mould produced accurate identical parts which were durable and functional. While the mould may have a limited life, the product it produced is just as good as anything from a CNC injection mould,” said Ken Nunn of Southways Consulting who was commissioned by VCM Suite to oversee the project.

Ray Piper, Director of Beza Patterns added “The FDM mould is cheap and a great way to get to market quicker. FDM moulds certainly have a place in the production schedule.”

Delivering High Quantities of Prototypes Fast

Objective3D Direct Manufacturing produces parts using a range of additive and conventional manufacturing technologies. We offer tailored solutions for your project’s needs. If your project requires larger quantities of small parts – fast, Laser Sintering is the best technological solution for you. Per-part pricing is reduced as quantities increase, but there are more advantages to using Laser Sintering for small prototypes than price alone.

Laser Sintering (LS) provides strong, versatile and geometrically intricate components made from filled and un-filled nylon materials that are ideal for fit and form verification and functional testing. Prototypes made with LS are created quickly and offer robust solutions for your project.
FAST Delivery Laser Sintering can provide sturdy, functional prototypes as little as 24 hours. Multi-component designs can be incorporated into single structures, allowing engineers to produce complex features and geometries in one print, and eliminating the need…

3D scanning and reverse engineering streamline original furniture design and production

MU Form Furniture Design is an Oakland-based company that designs, manufactures and distributes furniture products for the modern home and business. The company is never short of orders since good and original design is sought after by architects and interior designers.

The main material MU Form works with is high-quality bent ply, which is one of the most widely used materials in this industry due to its ability to create a variety of shapes for chairs, stools, and tables.

The company’s specialists seek to create great designs that pose a challenge for other manufacturers to copy or replicate.

“Our designers are tasked to develop furniture designs that require a significant amount of trial and error by developing physical prototypes of chairs and stools,” says Mark Leong, CEO of MU Form.

To produce a new original piece of furniture, MU Form would normally ship a physical prototype model to a factory overseas so they reverse engineer the model by using a router duplicator to create a …

Commodore Ute to US: 100,000 votes needed!

According to The Age Drive and an article by Barry Park, we are again set to export our Commodore Ute to the US.

The article is as follows:

US website rallies to GM's Twitter call of 'If you ask for an El Camino ute, we'll do it'.

An off-the-cuff quip from General Motors' newly appointed chief marketing officer could be just the thing to help Holden's cause to sell the Commodore ute in the US.

Joel Ewanick, who made the jump from Hyundai to the US car maker late last year, recently joined the social networking service Twitter. He soon started interacting with Chevrolet fans, with many of them asking for the car maker to re-introduce a vehicle based on a cross between a truck (ute) and a car.

In response to one passionate request for a new-age El Camino, Ewanick wrote: ''Well, we need you and 100,000 more of your best friends.''
