Our history

October 2005

A humble beginning

Prototype Solutions Group, Inc. opened its doors for business in October 2005 in Menomonie, WI. With combined experience in prototyping and product development, five founders including Alan Anderson, Kurt Bengtson, Tom Budd, Scott Hearley and Karen Halvorson-Falk, set out to create a full-service rapid prototyping firm.

With a humble beginning, PSG leased a 10,000 square foot facility (once a potato chip factory) and started serving clients with three CNC machines, six casting tanks, one 3D printer, and one paint booth. With just three employees in the first four months of operation, PSG was off to a successful start working with small businesses to Fortune 500 companies and government agencies.

July 2008

Leased no more!

In just three short years, PSG purchased the facility in July 2008.

2009–2011

Expansion of capabilities

Several manufacturing machines were added to the production floor in these few years:

  • Purchase of first 5-axis CNC mill in 2009
  • Acquisition of pad printing business in 2010
  • Purchase of first FDM machine in 2011
  • Purchase of 150 watt laser system in 2011
  • Acquisition of a model shop from a local manufacturer in 2011
February 2012

Busting at the seams

As employee count grew quickly it wasn’t too long before manufacturing space was limited. Expansion began in February 2012 with the addition of 14,000 square feet to nearly double the amount of manufacturing space.

September 2013

Cast away

PSG purchased a new heated casting tank for additional casting capabilities. This new tank is 4 feet in diameter and 6 feet long.

December 2015

Going live!

PSG invests in live tooling capabilities to increase efficiencies and versatility to the CNC shop.

October 2016

Large frame SLA

With the purchase of the ProX 800, PSG increased their SLA build envelope size to 25.6" x 29.5" x 21.65".

2019 -2022

CNC demand

To keep up with the demand for CNC services and to expand machining capabilities, PSG purchases five new machines within three years:

— 3x DMG-MORI CMZ 1100 Vertical Mills

— 1x DMG-MORI CLX 450 TC Lathe

— 1x DMG-MORI CLX 450 Mill Turn

2021-2022

Investing in quality

PSG invests in quality by developing a Quality Management System and purchasing Keyence quality equipment to increase inspection capabilities.

July 2022

Prototek acquires PSG

PSG is acquired by Prototek Holdings LLC ("Prototek"), a leading North American digital manufacturing provider of CNC machining, sheet metal and industrial 3D printing. Prototek operates in 11 facilities across the US, with over 300 employees and more than 250,000 square feet of manufacturing workspace. This new partnership will allow PSG to offer the same great service with additional manufacturing capabilities and capacity to better serve client needs.

Present
