> Ron Clemons and Mike Miller needed info on bureaus using 8100 resin. I
>have beta tested this resin for DuPont and I am currently using it in my SLA
>500 machine. My customers are very pleased with this resins flexibility. It
>lets them do snap fits over and over many more times than with the other more
>brittle resins. Side wall quality at .004 and .006 is excellent. This is also
>a very fast resin, my Ec is 7.3 and Dp is 5.9. Even though this resin is
>flexible it still has rigidity at the thicker wall thicknesses, so customers
>that do not need flexible materials can still have their parts made from 8100
>resin and be satisfied. If you do need to swap out vats between 7100 and 8100
>it only takes about a half an hour because the two resins are very
compatable. This resin also machines well and sands very smooth. Clean
up using TPM and ISP alcohol is very easy. Support removal is really
easy, a putty knife wilI slide right under the base and lift off the
>part with out any chipping. If any one has any other questions feel free to
>ask. I will do my best to answer your questions. If you need parts built call
>(724) 337-3836 or e-mail robert.speer@alcoa.com we do build for customers

> PROACTIVE FINANCE GROUP, LLC TO PURCHASE BFGOODRICH'S REMAINING INTEREST
>IN DTM Corporation
> (PR Newswire; 01/11/99)
>
>
>
> Agreement Approved by DTM Board of Directors
>
> AUSTIN, Texas, Jan. 11 /PRNewswire/ -- DTM Corporation (Nasdaq: DTMC)
>announced today that its Board of Directors has approved the purchase of
>3,157,190 shares of its common stock by Proactive Finance Group, LLC from
>its controlling shareholder, The BFGoodrich Company (NYSE: GR). BFGoodrich
>and Proactive have entered into an agreement for Proactive to purchase
>BFGoodrich's shares of DTM common stock and a $907,000 receivable due to
>BFG from DTM. Financial terms of the transaction have not been publicly
>disclosed. The sale remains contingent on Proactive's receipt of financing,
>as well as other customary conditions. The sale is expected to be completed
>in February. Since the time of DTM's initial public offering in May 1997,
>BFGoodrich has indicated that its investment in DTM was not strategic and
>that it intended to sell its remaining interest at some point.
>
>Effective upon the sale of the shares to Proactive, the BFGoodrich
>executives who are members of DTM's Board of Directors, Les C. Vinney,
>Robert D. Koney Jr. and Marshall 0. Larsen, will resign. Three persons
>nominated by Proactive, Anthony Mariotti, Samuel A. Myers and Larry
>Goldstein, have been appointed to fill the resulting vacancies.
>
>Anthony Mariotti, a Proactive Principal, stated, "We support management's
>plan for future growth and we believe that many of the elements for
>successful operations are in place. We intend to help position DTM to
>enhance shareholder value."*
>
>John Murchison, III, DTM's President and CEO, stated, "The management of
>DTM looks forward to working with a more entrepreneurial investor like
>Proactive. Proactive's investment in DTM comes at a time when we believe
>that we are beginning to see improved operating conditions. While results
>are not yet finalized, we believe that we met our goals and achieved a
>profit in the fourth quarter. This would be DTM's first quarterly net
>income. We also believe that top line growth was achieved for the quarter
>and the year. While much work still must be done and many risks remain,
>this would represent three consecutive quarters of revenue growth on a year
>over year basis. The Sinterstation Model 2500plus, our new and improved
>selective laser sintering system, enhanced our fourth quarter gross
>margins. Substantially all fourth quarter products sales were of products
>that we were not selling a year ago."*
>
>Since BFGoodrich will no longer provide its guarantee after the purchase of
>its shares by Proactive, DTM must replace its current $2.0 million bank
>credit line.
>
>This new credit line, if available, is expected to bear higher costs. At
>this time there is no balance outstanding on DTM's bank line of credit.
>However, DTM borrowed and repaid $1.3 million in the fourth quarter.
>
>Additionally, the $907,000 owed to BFGoodrich that is to be acquired by
>Proactive is currently non-interest bearing. Proactive has indicated to DTM
>that upon closing of the transaction it intends to formalize this balance
>into interest bearing debt.
>
>Proactive Finance Group, LLC is a privately held financial services and
>investment firm based in Austin, Texas.
>
>The BFGoodrich Company provides aircraft systems and services and
>manufactures performance materials that are sold to customers worldwide and
>used in thousands of consumer and industrial products.
>
>DTM Corporation develops, manufactures and markets the Sinterstation(R)
>family of rapid prototyping products for application in the rapid
>manufacturing marketplace. The Sinterstation(R) systems, and materials are
>based on proprietary and patented SLS(R) selective laser sintering
>technology. The Company's products are used to accelerate the design,

>cause actual results to differ materially and adversely from those set
>forth in the forward-looking statements, including, without limitation:
>
>- -- DTM has been unprofitable since inception; -- The Company's current

>Nasdaq National Market, further reducing liquidity;
>
>- -- Additional capital sufficient to finance the business may not be
>available or if available might cause significant dilution;
>
>- -- Quarterly fluctuations in operating results and the difficulty in
>predicting results of operations may adversely affect stock prices;
>
>- -- DTM may not emerge as a market leader, or even a major market
>participant and its markets may not develop;
>
>- -- The shareholder class action litigation pending against the Company;
>
>- -- Price reductions, reduced margins and loss of market share may occur as
>a result of increasing competition;
>
>- -- The Company's dependence on a single product that is priced at the high
>end of the range for today's rapid prototyping products has caused it to be
>adversely affected in a soft market; -- The Company's intellectual property
>and proprietary rights may not be valid or infringe the rights of others;
>- -- DTM may fail to manage or experience future growth;
>
>- -- Key personnel may leave; -- Suppliers may cause disruptions; -- DTM has
>significant international operations with the inherent exposures; --
>Actions by controlling shareholder could adversely affect stock prices; --
>Potential liabilities resulting from undetected errors or defects in
>Company products; -- Possible issuance of preferred stock could adversely
>affect common shareholders;
>
> -- Sales of a large block of stock and sales of shares issuable pursuant
>to employee stock options could adversely affect stock prices; and
>
>- -- The Company's stock price could be volatile, regardless of DTM's
>financial performance.
